AUGER BIT ASSEMBLY FUELING. Take the Allen key and box spanner (small end) and undo the bolt that passes through the end of the auger bit.. Once the bolt is removed you can slot the auger over the end of the power unit drive shaft. 3. Align the hole in the shaft with the holes in the auger bit.. Fill the mixing bottle with fresh unleaded petrol to the fuel level line. You MUST only use fresh unleaded fuel and stroke engine oil mixture.. For the first time ONLY a mixing ratio of 5: should be used to lubricate all engine parts to an optimum level. Thereafter the mix is 40:. 4. Pass the bolt through the auger and shaft then fit the nut and fully tighten. 3. Unscrew the fuel tank cap and carefully add the fuel/ stroke mixture as in section. DO NOT overfill and allow a 5mm gap at the top of the tank. Once full replace and correctly tighten the fuel cap. DO NOT use straight unleaded petrol. From empty the fuel tank holds 800ml.

STARTING & STOPING PROCEDURE MAINTENANCE. Before starting make sure machine is clear of materials and all non-essential persons.. Put the power switch to ON position. Move the choke lever to START position. 3. Press the primer bulb 7/8 times. Holding the machine firmly pull the recoil starter handle until machine starts. 4. When machine starts adjust the choke lever to the RUN position until machine runs smoothly. Allow the engine to warm up for a few minutes. 5. Put the switch to ON position. Make sure the choke lever is in the RUN position. Holding the machine firmly pull the recoil starter handle until machine starts. Allow the engine to warm up for a few minutes.. Position the machine in such a way that it cannot move during use, maintenance, cleaning, adjustment, assembly of accessories or spare parts, as well as under storage.. DO NOT change the engine governor settings or over-speed the engine. The governor controls the maximum safe operating speed of the engine. 3. Use only attachments and accessories approved by the manufacturer. 4. Maintain the machine and check for misalignment or binding of moving parts, broken parts and any other condition that may affect the machine s operation. If damaged, have the machine repaired before reuse. 5. Keep the engine, exhaust and muffler free of grass, leaves, excessive grease or carbon build up to reduce the chance of a fire hazard. 6. Keep handles dry, clean and free from debris. Clean the machine after each use. 7. Thoroughly inspect the area to be worked, keep the working area clean and free of debris to prevent tripping. Operate on a flat level ground. 8. Keep all bystanders, children, and pets at least 3m (75 feet) away. 9. Before starting the auger, make sure that the area to be drilled is free of all underground obstacles such as power cables, water and drainage pipes. 6. Before stopping the machine allow the engine to cool down for a few minutes, by allowing it to run without throttle. You MUST allow the auger drill bit to come to a full stop before carrying out any maintenance on the machine. Allow the machine to cool down with no throttle applied. Turn the power switch OFF. If not already in RUN position move the choke to the RUN position. 0. NEVER allow an accumulation of earth or drilled material to build up on the earth auger drill bit, this will prevent proper discharge from the hole and will make the auger heavy to handle.. NEVER attempt to unclog either the auger drill bit while the engine is running. Immediately shut off the engine. Allow the auger drill bit to come to a complete stop. Remove the clogged material. Inspect for damage and check for any loose parts for repair or replacement. PAGE 6 PAGE 7
OPERATION AIR FILTER. Before starting - inspect machine and work area for any danger.. Start slowly with half throttle and keep a firm grip on both handles of the auger at all times. Keep a wide stance. 3. After engine warms up Accelerate the engine, to accelerate the engine to working speed squeeze the throttle lever toward the main handle. 4. DO NOT force the auger drill bit into the ground. If the machine jams you MUST release the throttle and move the auger drill bit before re-commencing work. Never let the engine run without the air filter being fitted. A dirty air filter element affects the engine performance, increases fuel consumption and makes it difficult to start. You MUST make sure that the housing is free of dust and debris. DO NOT allow any dust or debris to enter the carburetor.. Push clip () down and pull filter cover () away from machine, take care to release lower clips (3).. Remove the filter (4) by pressing clip (5) and lifting filter clear. 3. Wash with soap and water. Never use petrol or benzene! 4. Allow the filter to air dry. To replace the filter reverse the above process. 5. To remove blockages DO NOT under any circumstances use your hands. STOP and disable the machine and clear the auger drill bit of materials which have become stuck to auger bit. 7. Check and maintain fuel level regularly, and maintain the fuel/oil mix to the correct ratio. Frequently check the auger and make sure that all deposits are removed from the auger drill bit. 8. At regular intervals, check the tightness of all nuts, bolts and screws. If the auger drill bit hits an obstacle check for damage. If the machine vibrates badly stop the machine and take it to a service dealer. 9. NEVER use a pressure washer to clean your auger. Water can penetrate the power unit and cause damage the engine. The use of pressure washers will result in shortened life and reduce serviceability. Shut down the engine, wait for all moving parts to come to a complete stop, remove HT lead, and then wait for 5 minutes before performing maintenance on the tool. PAGE 8 PAGE 9
FUEL FILTER SPARK PLUG. A clogged fuel filter can cause lack of power and poor pickup. Check the fuel filter every 5 use hours.. Remove the fuel cap and empty the remaining fuel into an approved container. 3. With a small wire hook pull out the fuel line and filter out of the tank. 4. Disconnect the filter spray with a carburetor cleaning solvent then clean by blowing air from inside filter to outside. Reverse to process to re-instate the filter. Replace filter as required.. The spark plug MUST be fully tightened otherwise the engine will overheat causing damage. Always complete the following steps after the engine has been turned off and allowed to cool down.. To make sure the engine runs correctly a spark plug gap of 0.6-0.7 mm must be maintained and the spark plug must be free of carbon deposits. 3. To remove the spark pull off the HT lead and then undo the spark plug using the supplied box spanner/t bar in an anti-clockwise direction. 4. Once the plug has been removed check it for visual damage, electrode wear and carbon deposits. Replace a damaged or badly worn spark plug. Clean off any carbon deposits by using a soft brass brush. 5. Check the gap with a feeler gauge and adjust electrode at the correct gap of 0.6-0.7 mm. 6. Check the spark plug washer for damage and replace if required. 7. Refit the spark plug by hand to make sure it does not cross thread, tighten the spark plug to a torque of /5Nm. PAGE 0 PAGE
GEAR BOX STORAGE. Use a high temperature gearbox grease.. Check the gear box grease every 30 hours of use and fill as required. Thereafter check and top-up after every 5 hours. N.B. 0 grams is sufficient for a full top-up. 3. To fill with or top-up with grease apply grease with a grease gun to the grease nipple. 4. Recommended change interval. st check after 30 hours of use. Thereafter every 5 hours of use. 5. If you do not follow these steps, deposit may arise in the carburetor. This will cause starting difficulties and may cause permanent damage.. Clean the outside of the machine, drive axle, shield and nylon cutting head.. Remove all fuel from the fuel tank. 3. After all the fuel is drained, start the engine. 4. Allow the engine to run in idle until engine stops alone. This allows the fuel to be removed from the carburetor. 5. Allow engine to cool down (about 5 minutes). 6. Use a spark plug wrench, remove the spark plug. 7. Pour teaspoon of clean -cycle oil into the combustion chamber. Slowly pull the starter rope several times to coat internal components. Replace the spark plug. 8. Store the machine in a cool, dry place away from any source of ignition such as an oil burner, water heater etc. 9. When transporting the machine make sure that no fuel is allowed to leak out.
