Engines |
|
| Q: | ENGINE WILL NOT START OR STARTS BUT THEN STOPS |
| A: | 1. Check there is sufficient fuel in the tank. 2. Check the oil level (the oil alert will stop the engine if it is too low or the engine is on too great an angle) 3. check the on/off switch is set to ON. 4. Check there is no foreign matter (particularly water) in the carburettor 5. If the engine will only run smoothly on part choke, it is usually that the main jet is partially blocked due to stale fuel residue or water deposit. |
| Q: | HOW DO I KEEP THE DUST FROM MY AIRCLEANER? |
| A: | Important: only genuine air cleaner parts get the best out of your engine! When replacing the SUBARU cyclonic-aircleaner element, a smear of grease around the entire circular base makes the perfect dust-proof seal. Remember to clean the dirty grease build up from the air horn during the next scheduled service. |
| Q: | HOW DO I SET THE TIMING ON EX ENGINES |
| A: | Align gold links on timing chain with timing dots on cam gear and crankgear. |
| Q: | HOW OFTEN SHOULD I CHANGE THE OIL ON MY SUBARU DIESEL ENGINES? |
| A: | DY23 and DY27: Although the owner's handbook specifies no oil change is required before 100 hours of running time has occurred, it is preferable to change the oil at 50 hour intervals. DY30,DY41 AND DY42 The owner's handbook specifies changing the oil at 50 hours and this is sufficient. NOTE: On all models, it is imperative to change the oil at regular intervals, plus clean the filters. |
| Q: | HOW OFTEN SHOULD I CHECK THE OIL LEVEL ON MY NEW ENGINE? |
| A: | Regardless of make, model or size of engine, it is imperative that the oil level be checked frequently, e.g. after every tank full of fuel until the motor has properly bedded rings to cylinder. This is even if the motor has a sensor unit, as the location or angle of the machine can cause false readings. |
| Q: | OIL FOR EH025 AND EH035 SERIES |
| A: | Used on brushcutters, blowers, blower vacs, portable vibe shafts. The owners manual suggests 10w-30 oil. Unfortunately weather temperatures above 20 degrees can cause excess oil in the air filter of these engines. We suggest (as per the service manual) that 30 grade mono be used consistently. |
| Q: | REASONS FOR CARBURETTOR FLOODING? |
| A: | 1. Air vent hole blocked (common on drive units, cement covering carburettor) 2. Foreign matter in carby (make sure tank and filters are kept clean) 3. Pin hole in float 4. Float jammed on stem of carby 5. Incorrect float level NOTE: As all new carburettors are fitted with Neoprene tipped float needles, most flooding problems are caused by numbers 1 and 2 above. When removing float pin, use caution - one end is flat to lock in the leg. This must be pushed away from the centre. |
| Q: | RESTRICTOR ON ENGINES |
| A: | Most small engines such as SUBARU, Honda, Briggs & Stratton, etc. when fitted with a Donaldson or similar type of air cleaner, require some sort of restrictor to prevent the engine hunting. When replacing any part of the intake system make sure the restrictor is fitted. (An exception to this is the SUBARU EH41 and SUBARU twin cylinder motors as they do not need restrictors. |
| Q: | STICKY INTAKE VALVE - DON'T GET STUNG! |
| A: | There are often reports of wasps building nests in the exhausts of small engines. The symptoms indicate a sticky intake valve, whereas it is actually the muffler that is blocked. Usually this problem is usually after a long storage period, though in one instance the muffler blocked over a weekend. |
| Q: | WHAT ARE THE CORRECT TERMINALS FOR CONNECTING BATTERIES TO AN ELECTRIC START MOTOR? |
| A: | The RED WIRE POSITIVE (+) is connected to the POSITIVE (+) terminal of the battery. The BLACK WIRE NEGATIVE (-) is connected to the NEGATIVE (-) battery terminal. |
| Q: | WHAT IS AN OVERHEAD CAM? |
| A: | (OHC) A Camshaft Mounted above the Head to Activate the Valves is driven by a timing (cam) chain. Direct valve activation by a cam eliminates the need of pushrods and rocker arms, and their accompanying lash and inertia. Valves respond quicker, valve adjustment can be more accurate, and engine speed can be higher. OHC Engines Offer Mechanical Advantages over Comparable Size Pushrod Engines: |
| Q: | WHAT IS AN OVERHEAD VALVE? |
| A: | (OHV) Valves Located in the Cylinder Head. Valve actuation is via pushrod and rocker arm. In a four-stroke engine, the intake and exhaust valves are in the cylinder head. The valve stems are either at an angle or parallel, and the valve discs face the piston. |
| Q: | WHAT IS THE BEST OIL FOR 4-STROKE SUBARU ENGINES? |
| A: | The best engine oil for your petrol-powered, 4-stroke SUBARU engine is a high-quality, mono-grade 30W oil and NOT a multi-grade. The rings on new engines will not bed properly if a multi-grade oil is used - you will just end up with a beautifully glazed bore! |
| Q: | WHAT IS THE BEST WAY TO STORE SMALL ENGINES FOR WINTER? |
| A: | 1. Drain fuel from tank and carburettor 2. Remove spark plug and squirt a small amount of engine oil into the cylinder 3. Replace plug and wind motor over 2 or 3 times 4. Bring the piston up on compression stroke. (If in damp conditions, put tape over the intake and exhaust and give unit a light spray with a mix of diesoline and oil or similar.) |
| Q: | WHAT IS THE CAUSE OF ENGINES 'HUNTING'? |
| A: | The most common cause of engines ‘hunting or surging’ is stale fuel evaporating, leaving residue on the main jet or dirty fuel causing partial blockage of the jet. If the motor runs smoothly on partial choke, this usually indicates main jet restriction. **Other causes can be worn or cracked carburettor insulators or poor sealing gaskets. If the carburettor is damaged on the right hand side near the blower housing this will cause the engine to hunt or suge as it will provide increased air flow across the back of the carburettor vent which will upset the fuel level. In this instance a replacement of the insulator will be necessary. |
| Q: | WHICH OIL SHOULD I USE FOR THE SUBARU EH025 & EHO35 SERIES ENGINES? |
| A: | These engines are used on brushcutters, blowers, blower vacs and portable vibrator shafts. The owners manual suggests 10w-30 oil. Unfortunately weather temperatures above 20 degrees can cause excess oil in the air filter of these engines. We suggest (as per the service manual) that 30 grade mono be used consistently. |
| Q: | WHY IS FUEL LEAKING INTO ENGINE CRANKCASE |
| A: | When experiencing fuel in the oil of engines the first step is to check the needle and seat are in good condition. Often leaking can be caused by the fuel tank cap vents being blocked – or in extreme cases, by the tank being fitted with a non-spill cap. |

Flooring Machines |
|
| Q: | CAN THE PORTA-NAILER BE USED TO NAIL VARIOUS THICKNESSES OF TONGUE AND GROOVE FLOORING? |
| A: | Yes. The Porta-Nailer is designed for nailing 33/32" and 25/32" tongue and groove flooring. An accessory nailing shoe is available for nailing 7/16" to 9/16" flooring with the standard 2" Porta-Nail. There is also an angled shoe base available for use with the 401 nailer to nail 25/32" flooring over 3/4" plywood over concrete. |
| Q: | DO YOU HAVE TO GO BACK AND SET UNSEATED NAILS WITH PORTA-NAILER? |
| A: | No. the Porta-Nailer has a ratcheting feature designed to insure every nail is properly seated. The ram of the nailer will not return to its original position until the nail is seated. If the ram does not return, it is telling you that another blow of the hammer is required. |
| Q: | HOW MANY PORTA-NAILS WILL I NEED TO INSTALL MY NEW TONGUE AND GROOVE FLOOR? |
| A: | 1,000 nails will install approximately 18.5 square metres of flooring. |
| Q: | I AM INSTALLING PRE-FINISHED FLOORING, WILL THE PORTA-NAILER MAR OR SCRATCH THE SURFACE OF THE FLOORING? |
| A: | When installing a pre-finished floor, you need to take care in the handling and installation process. The Porta-Nailer is designed not to damage the flooring. The shoe bases are made of a non-marring material and the hammer rubber cap is made of a non-marring material to protect the pre-finished surface. |
| Q: | I AM NAILING INTO THE GROOVE OF THE FLOORING, IS THIS CORRECT? |
| A: | No. You should be nailing into the tongue of the flooring. |
| Q: | WHEN NAILING, HOW MUCH SPACE SHOULD BE ALLOTTED BETWEEN FASTENERS? |
| A: | You should always refer to the flooring manufacturer's specifications for installation requirements. Generally, every 15 to 20 cms is a good rule of thumb. |
| Q: | WHY ARE NAILS BENDING DURING OPERATION OF THE PORTA-NAILER? |
| A: | 1. It is important to keep at least a 5cm (2") clip of nails in the tool. Individual or loose nails can get out of position and when contact is made with the driver blade, bending can occur. 2. Make sure the tool is being used with the pusher in place. Again, tension needs to be placed on the nails in the tool. 3. The end of the driver blade should be flat. If the end (contact surface) of the driver blade has become worn or rounded this could cause a jam or bending of nails. **If you have checked all of the above items and are still experiencing bent nails, open a different box of nails. If bending is still happening, then this most likely points to a wear issue with the actual tool or perhaps the operator's technique. |

General Trade |
|
| Q: | EARLEX SM5 WALLPAPER STEAMER STOPS AND STARTS |
| A: | If the steamer stops steaming for a short period and then restarts a common cause is a build up of calcium or similar deposits on the element, which results in heat retention. It is easily solved by removing the element and scraping off any deposit visible. |
| Q: | HOW DO I PREVENT THE THERMOSTAT ON THE EARLEX WALLPAPER STEAMER FROM OPERATING PREMATURELY? |
| A: | To prevent this happening which will cause the unit to stop steaming for short periods of time, make sure you empty the water out after using. This will help to prevent a built up of scale on the elements which is the major cause of this problem. The life of the steamer will also be extended by not leaving water in the tank. |

Generators |
|
| Q: | CAN I RUN MY GENERATOR AT LOWER SPEED TO CONSERVE FUEL? |
| A: | The power supply required to operate Australian appliances is 240 volts. If the set speed is reduced the voltage is reduced proportionally and can result in damage to the appliance. |
| Q: | My Inverter Generator is running rough, running for short periods then stopping and it's voltage drops after a short period of time. |
| A: | Possibly the Spark Plug requires replacement. We recommend keeping with the original NGK plug. Inverter Generators require resistor type spark plug. The use of a non-resistor type plug will case the generator to malfunction. |
| Q: | WHAT IS 'TOTAL HARMONIC DISTORTION'? |
| A: | There is currently a lot of misleading information in the marketplace regarding “Total Harmonic Distortion” (THD) in relation to generators. Terms such as this, and also “Sine Wave”, are used along with “Clean Power” and “Perfect Wave Form” when referring to the output from generators. One Australian manufacturer is using these terminologies as a marketing tool, advertising their generating sets as “the cleanest power around”, due to their THD percentage. They claim that “most portable generating sets” have over 25% THD. Independent University testing has shown that the Total Harmonic Distortion of CROMMELINS Generators tested is only 6%, well below the “said” 25%! |
| Q: | WHAT TYPE OF SPARK PLUGS SHOULD I USE FOR MY SUBARU INVERTER GENERATOR? |
| A: | When fitting or changing spark plugs in SUBARU Inverter type generators a resistor type spark plug must be used. Use of a non-resistor type plug will case the generator to malfunction. |

Himoinsa |
|
| Q: | 120V BETWEEN EARTH AND NEUTRAL |
| A: | Some Single Phase Generators may be producing voltage of 118 volts between the earth to neutral connections which does not comply to australian standards. This is due to the way the himonsa factory wires up the alternator. Check that the Single Phase wiring is correct. Contact Service for more information. |
| Q: | 240 VOLTS BETWEEN EARTH AND NEUTRAL AT POWER OUTLETS |
| A: | The cause is incorrect wiring. Change the polarity of the L1 and L2 cables either at the main circuit breaker, or if it is only a certain power outlet that is the problem, change the polartiy at the circuit breaker for that outlet. |
| Q: | FAULTY VOLT METER, FREQUENCY METER, AMP METER, HOUR METER |
| A: | The cause is a bad connection or faulty meter. Check cables connections at the faulty meter. Check to see if 240 volts is present at the back on terminals while machine is running. Make sure cables marked 33 and 34 at main RCD have a good connection at terminal. |
| Q: | RCD WILL NOT TRIP OUT ON A 30MA FAULT LOOP IMPEDENCE TEST |
| A: | There may be a bad connection in the GPO circuit, a faulty RCD or a faulty GPO. Solution 1: Make sure the polarity at the outlet and voltage between: Active – earth – (240 volts), Neutral – earth – (0 volts), Active – neutral – (240 volts) Is correct. Solution 2: A bad connection at the M.E.N. (normally found at the main switch) make sure connection is made between earth and neutral. Solution 3: Make sure no voltage is between neutral and earth. If there is, see '120v between earth and neutral’ troubleshooting guide under altenators for more details. Solution 4: RCD could be faulty, change with a new one. Solution 5: Try a different testing instrument. |

The himoinsa generators have 4 starting conditions; only 1 is needed to be detected to start the engine. Solution 1: Disable the starting condition for the low oil pressure. Refer to manaul Crommelins Service for more information. Solution 2: The engine could be the cause and needs to be repaired. |
| Q: | CEM6/7 IS DISPLAYING A ERROR MESSAGE ‘OVERSPEED’ |
| A: | The engine is running too fast. Adjust engine speed at the govenor or if the engine is fitted with a electric govenor, it could be that the speed sensor is unplugged or faulty. |
| Q: | COMMUNICATIONS ERROR IS SHOWING UP ON THE CONTROLLER SCREEN |
| A: | There is a bad connection from the PHG6 module and the display module. Check connection and continuity of the cable between the PHG6 module and the display module. There are 2 cables that join the phg6 module and the display module. The cables at terminals marked ‘canl’ and ‘canh’ on the phg6 module, are connected to the display module terminals ‘canl’ and ‘canh’. Make sure continuity of cables are good and at a low resistiance. At cable terminals canl and canh, double check terminals connections. Micro switches are in the wrong position. Make sure both micro-switches are in the ‘on’ position. If either one of the micro switches is in the ‘1’ position then that could cause the problem. |
| Q: | CONTROL IS SHOWING AN ERROR ‘UNEXPECTED SHUTDOWN’ |
| A: | The unexpected shutdown of the CEM6 is triggered when the engine is running; it does not detect all the engine starting conditions. Refer to starting conditions guide for more information or Contact Crommelins Service. |
| Q: | DISPLAY FOR THE CEM6 / CEM7 IS BLANK AND IS NOT WORKING (WONT SHOW) |
| A: | The battery cable may not be connected. Check battery cable is connected. Battery also might be faulty, so check if the battery is charged and is in good working condition. The isolator may have an open circuit. Check battery isolator is in working order. Make sure the isolator opens and closes the circuit, and is not permanently open. J1 connector is not connected. Check to see if the J1 connector is connected to the control panel. (it is located behind the control panel, and is a 16-pin connector) Blown fuse(s). Open the control panel front cover, and locate fuse F0. Check fuse continuity, replace if fuse is faulty. Check fuse F1 (fuse for keystart switch), if faulty then replace with new. Fuse 0 (F0) – 40A fuse Fuse 1 (F1) – 2A fuse A bad connection behind the display module or the display module could be faulty. Check connections behind the controller to make sure there are good Finally, the display module could be a faulty and may require replacement. |
| Q: | EMERGENCY STOP ERROR DISPLAYING ON SCREEN. |
| A: | The emergency stop button may be engaged. Check to see if emergency button is engaged, if so release the button and hold the reset button for 5 seconds. The emergency stop is permanently open. Check to make sure emergency stop button switch is functional (not always closed). There is a bad connection at controller. Check connections at stop switch, make sure tight and good continuity. Check connection at PHG6 module, terminals ‘pem’ and ‘seta’. |
| Q: | FAILURE TO STOP IS SHOWING UP ON CEM6/7 CONTROLLER SCREEN |
| A: | If there is sudden stop of the genset and oil pressure remains in the engine you will need to disable the starting condition for the low oil pressure. Press V to bring up password screen. Type the maintenance password > Go to paramaters > Go to regulations > Go to P022 (low oil pressure starting condition ) value default is 2. Once P022 is highlighted press V, now the value should then be highlighted. Change the value from 2 to 0 (2 = Automatic Detection, 0 = OFF). Once value is changed to 0, press V to confirm. Turn controller off by the key, turn battery isolator on / off. Turn controller on, problem should now be gone |
| Q: | HOW CAN I WIRE AN EXTERNAL SWITCH ON A CEM6/CEM7 CONTROLLER |
| A: | The CEM6/7 controllers don’t come with an external start/stop switch so one has to be wired in. Please note that it has no dry contacts like an M6 controller. Contact Crommelins Service Dept for a diagram. To wire a external switch: 1) On the PHG6 module (black box located in the electrical panels ) terminal on the top marked ‘ENT 4’ is for a external switch 2) A cable need to go from terminal ENT4 to 'BORNES x3', which is commonly found on the very bottom of the electrical panel (directly underneath the phg6 module). 3) Find the cable marked ‘017’, which should enter terminal 6 on the BORNES x3 (This is where one cable goes to, for the external switch). 4) The other cable needed is from the battery negative which can be found on 'BORNES x3' on terminal 1. 5) Once these two cables form a circuit, the genset will start while in auto mode. *note* battery negative cables are always marked ‘1’ on every unit. |
| Q: | HOW DO I NAVIGATE AROUND THE CEM6/7 CONTROLLER |
| A: | By pressing the ‘V’ button you will bring up a password screen. To enter a 4 digit password, you do it put pressing the up and down keys to change the numbers and X and V to go left to right, when the 4th digit is highlited and password is correct, press V again to confirm password. To access menus on the CEM6/7 controller, highligh the menu and press V to access, and X to return to previous menu. Contact Crommelins Service Dept or refer to your manual to find input passwords. |
| Q: | LOW COOLANT LEVEL FAULT DISLAYING ON CEM6/7 SCREEN |
| A: | If there is LOW COOLANT LEVEL Fault displaying on the screen it could mean low coolant level, bad connection in low coolant sensor circuit or the sensor is faulty Solution 1: There may be a low coolant level, make sure the radiator is topped up to the top. Solution 2: Broken or bad connection from the PHG6 to the low coolant sensor. Low coolant sensor cable is marked “15” and is in the terminal “NA” on the PHG6 module. Check continuity and terminal connections from the PHG6 module and the main connector. Check continuity and terminal connections from main connector to low coolant sensor. Solution 3: The Low coolant sensor could be surrounded by dirt. If normal tap water is used, this can cover the sensor in dirt, take the sensor out and clean it, which may make the problem go away. Solution 4: Disconnect the cable at the low coolant sensor. If sensor fault goes away then it’s a faulty sensor, replace sensor with new one. Solution 5: Disable the Low Coolant Sensor, Please contact Crommelins for more information. |
| Q: | LOW FUEL LEVEL (BY SENSOR) |
| A: | Solution 1: Broken or bad connection from the phg6 to the fuel sensor. Fuel sensor cable is marked “08” and is in the terminal “rc” on the phg6 module. Check continuity and terminal connections from the phg6 module and the main connector. Check continuity and terminal connections from main connector to fuel sensor. Solution 2: Someone has played around with the paramaters of the controller and has changed the fuel sensor paramaters. The factory settings for the fuel sensor will not shut down the machine, but it can be re-programmed. Contact Crommelins Service for more info. Solution 3: sensor could be faulty. Test to make sure sensor is ok. Testing the fuel sensor - Blue cable = common, Red cable = low alarm signal output, Black cable = level signal output, Yellow cable = high alarm signal output (not used). Cables blue and red the Float down should be around .60 OHMs and the Float up should be around 6-8 megOHMs Cables blue and black the Float down will be 330 OHMs and the Float up should be 0.3 OHMs |
| Q: | PROGRAMMING THE MAINTENANCE ALARM |
| A: | For your convience the maintenance counter in the Himoinsa machines has already been set for its first 50 & 150 hour service schedules. Please note: You will need to reprogram these settings after each service has been completed as the factory does not set this, it is set by the owner or by the operator of the genset. For the programmed service schedules – please refer to the owners engine manual. To Program: Press V to bring up password screen > Input maintenance password, press V to confirm A list will show up, scroll down to counters. On the bottom of the list it will have , Maintenance #1 & Maintenance #2. When maintenance #1 is highlighted, press V to change value, set the value to next preset service. |
| Q: | SCREEN IS SHOWING A LOW OIL PRESSURE FAULT |
| A: | Causes: A low oil pressure in the engine, a bad connection in the circuit, a faulty sensor. Solution 1: broken or bad connection from the phg6 to the low oil pressure sensor. Low oil pressure sensor cable is marked “06” and is in the terminal “BPA” on the PHG6 module. Check continuity and terminal connections from the phg6 module to the main connector. Check continuity and terminal connections from main connector to low oil pressure sensor Solution 2: Make sure that the engine doesn’t have any oil leaks. Run the machine up and check to see if engine runs at around 50-60psi (double check with engine manufacture for correct oil pressure reading). Solution 3: You may need to disable the starting condition for the low oil pressure. Press V > input maintenance pawssword, press V to confirm > Go to paramaters > Go to regulations > Go to P022 (low oil pressure starting condition) value default is 2. Once P022 is high lighted press V, now the value should then be high lighted. Change the value from 2 to 0 (value 2 = automatic detection, 0 = off) Once value is changed to 0, press v to confirm. Turn controller off by the key, turn battery isolator on / off. Turn controller on, problem now will be gone. Solution 4: Replace Low Oil Pressure Sensor with a new one. |
| Q: | THE CEM6/7 CONTROLLER IS SHOWING AN ERROR MESSAGE OF ‘INVERSE POWER’ |
| A: | The Inverse Power (reverse power) is caused when the power obtained (mains or genset) is negative, and exceeds the resultant value after calculating the programmed factor in a hundred per cent of the nominal power. Or basically check connection from the controller to the current transformer. |

Himoinsa - M6 CONTROLLER |
|
| Q: | FUEL RESERVE L.E.D WON’T TURN OFF EVEN WHEN THE FUEL TANK IS FULL. |
| A: | There is a bad connection from M6 controller to the fuel sensor or a faulty fuel sensor. Solution 1: Fix the bad connection from M6 controller to the fuel sensor. Check ‘terminal 15’ connection at M6 controller. Check connection ‘08’ at J1 connector. Check connection at fuel sensor. Solution 2: Check to make sure you have good contiunity (low restistance) from the controller to the fuel sensor. Solution 3: Faulty Fuel Sensor, replace with a new one. |
| Q: | LOW OIL PRESS L.E.D WON’T TURN OFF |
| A: | The causes of this issue cou be a Low Oil Pressure in the engine, a Bad Connection in the circuit or a Faulty Sensor. Solution 1: Broken or bad connection from the M6 controller to the low oil pressure sensor. Low oil pressure is connected to terminal 14 on the M6 controller. Check continuity and terminal connections from the M6 controller to the main connector (J1 connector). Check continuity and terminal connections from main connector (J1 connector) to low oil pressure sensor. Solution 2: Change low oil pressure sensor with a new one. Low oil pressure is N/C. Solution 3: Make sure that the engine doesn’t have any oil leaks. Run the machine up and check to see if engine runs at around 50-60 psi (double check with engine manufacture for correct oil pressure reading) |
| Q: | M6 CONTROLLER WILL NOT TURN ON. |
| A: | There are many reasons why a M6 controller could not be turning on. A blown fuse, the battery could be faulty, the battery isolator could be permently open, the J1 connector is disconnected or a bad connection at the M6 controller. Solution 1: Check fuse F1 (20A fuse) has continuity, if blown then replace with a new one. Fuse is located on the front controle panel. Solution 2: Check battery cable is connected. Battery also might be faulty, so check if the battery is charged and is in good working condition. Solution 3: Check battery isolator is in working order. Make sure the isolator opens and closes the circuit, and is not permanently open. Solution 4: Check to see if the J1 connector is connected to the control panel. (located behind the control panel, and is a 16-pin connector) Solution 5: Check back of M6 controller connection terminal 3 (battery negative) and terminal 6 (battery postive), is getting 24 volts across both terminals. Make sure connection is good and tight. |
| Q: | OVERSPEED L.E.D LIGHTS UP AND TURNS ENGINE OFF |
| A: | The overspeed internal protection device has triped because engine is going to fast. Adjust the engine governar to correct engine speed. This should be set at around 1500rpm for most engines. |
| Q: | THE AUTO START FUNCTION OF THE M6 CONTROLLER WON’T START THE MACHINE |
| A: | Close the dry contacts (located on the front controle panel). The M6 controller has 2 dry contacts (no voltage) that need to be closed in order to activate for auto (remote) start fuction. |
| Q: | THE AUTO START FUNCTION OF THE M6 CONTROLLER WON’T START THE MACHINE EVEN WITH THE DRY CONTACTS CLOSED |
| A: | There could be bad connection across the dry contacts or to the M6 controller. Check continuity between terminal ‘17’ (cable #09) and the dry contacts. The other end of the dry contact is the battery negative (cable #01). |
| Q: | THE EMERGENCY STOP L.E.D WON’T TURN OFF |
| A: | There is a faulty emergency stop or bad connection at the M6 controller Solution 1: Check to see if emergency button is engaged, if so release the button and press the reset button. Solution 2: Check to make sure emergency stop button switch is functional. The switch is normally closed, so if it’s normally open all the time its faulty. Solution 3: Check connections at stop switch, make sure tight and good continuity. Check connection at the back of the M6 controller, terminal ‘18’. |

Lawncare Equipment |
|
| Q: | GRASS CLIPPINGS ARE NOT DISCHARGED FULLY INTO THE CATCHER BAG ON MY LAWNCOMBER |
| A: | If grass clippings are not discharged fully into the Catcher Bag, the cause is normally because of worn blades. To correct this, rotate the blade carrier as described in the owner’s manual. |
| Q: | GROUNDHOG TRENCHER IS HUNTING AT HIGH SPEED |
| A: | As these machines have a Donaldson Air Cleaner attached, a restrictor is required for proper engine performance. This is fitted onto the base of the precleaner inside the air cleaner. When the need arises to remove or replace the precleaner, take care not to loose the restrictor. |
| Q: | HOW DO I MAINTAIN THE RECEIVER WASHER ON MY ROBIN BRUSHCUTTER? |
| A: | You will find this either behind the blades or the bump feed attachment (depending on which model you have). Removal of this washer at regular intervals to empty any trapped grass, weed, etc, will reduce head friction and prolong the life of grease seals for the angle head. |
| Q: | HOW DO I PROLONG CHAIN LIFE ON MY GROUNDHOG T4 TRENCHER? |
| A: | You can prolong the life of your Groundhog T4 Trencher chain with these easy steps: 1. Thoroughly clean digging chain with pressure cleaner and allow to dry. 2. Spary roller links with a dry lube (Promar). 3. After 6 to 8 hires move the chain on drive sprocket one link (sprocket only drives every second link). |
| Q: | WHAT IS THE DIFFERENCE BETWEEN BLADES FOR VERTIMOWERS/LAWNCOMBERS? |
| A: | A Lawn Comber is not designed to cut through the grass into the soil if fitted with Flail blades. If the standard Flail Reel blades that come with this machine are set too low excessive load is placed on the drive belt and causes the machine to bounce and can damage the blades and shafts. The Flail Reel blades are designed to just go through the grass and dip through the surface. If the customer wishes to vertimow deeper into the soil, Delta Blades should be fitted. |
| Q: | WHAT IS THE IDEAL TENSION FOR MY GROUNDHOG T4 TRENCHER CHAIN? |
| A: | The ideal tension on a new Groundhog Trencher digging chain produces 30-35mm travel between chain and chain bar. Remember to allow for wear and tear in the chain and sprocket-drive assemblies with time and that the chain-travel distance will then be the average of several measurements as the chain is moved around the guide bar. |
| Q: | WHY IS OIL DRIPPING FROM THE AIR CLEANER OF MY ROBIN BH2500 BRUSHCUTTER? |
| A: | This is perfectly normal as oil is misted into the filter automatically. If the element is cleaned as per the instruction manual, this leakage will be minimal. You should remove the element after five hours of use and squeeze out the excess oil. |

Pumps |
|
| Q: | I HAVEN'T USED MY FIRE FIGHTING PUMP SINCE LAST SEASON - WHAT SHOULD I DO TO MAKE SURE IT IS READY IF I NEED IT? |
| A: | 1. If not already done at the end of last season, change the engine oil. 2. Drain any fuel left in the tank and fill with fresh petrol. Loosen the fuel bowl retaining bolt on carburettor and allow fresh fuel to flush through. Tighten the bolt. 3. Remove the spark plug and put a couple of squirts or pour a little engine oil in the cylinder. Pull the motor over three or four times. Remove plug and rinse in petrol and replace. 4. Fill pump unit with water and start pump in normal fashion. The engine can be run for 1-2 minutes without connecting to the water tank as long as the pump is full of water. **If the motor does not start or run properly (lack of compression/blocked carburettor) it will be necessary to have the unit checked by your local service agent. |
| Q: | PUMPS FAILING TO PRIME |
| A: | A common cause of pumps failing to prime is air leaking a the hose fittings. A simple way to check this is to remove all hoses, fill the pump with water, start the motor and place your hand (if a 2-3” pump) over the suction port. (A damp but firm piece of cardboard or a sheet of rubber can be used instead of your hand for larger pumps.) If suction is felt, check the camlock or nut and tail seals, or the hoses for holes. Note: If the pump is fitted with a female camlock this will not work. |
| Q: | THE DY23/27 POWERING MY WATER PUMP IS HARD TO TURN OVER |
| A: | These engines fitted to water pumps that experience heavy and consistent use may become hard to turn over. One cause of this is wear to the crankshaft thrust bearing. Check this by measuring the end float of the crank, it should be .004TH - .012TH (.1 - .3 mm). If it exceeds these specifications, replace the thrust washer. |
