AUGER BIT ASSEMBLY
FUELING
1. Fill the mixing bottle with fresh unleaded petrol to the fuel level line. You
MUST only use fresh unleaded fuel and 2 stroke engine oil mixture.
2. For the first time ONLY a mixing ratio of 25:1 should be used to
lubricate all engine parts to an optimum level. Thereafter the mix is 40:1.
3. Unscrew the fuel tank cap and carefully add the fuel/2 stroke mixture as
in section 2. DO NOT overfill and allow a 25mm 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.

MAINTENANCE
1. 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.
2. 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 23m (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.
10. 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.
11. 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.
1. Before starting make sure machine is clear of materials and all
non-essential persons.
2. 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.
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.

AIR FILTER
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.
1. Push clip (1) down and pull filter cover (2) away from machine, take care
to release lower clips (3).
2. 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.
1. Before starting - inspect machine and work area for any danger.
2. 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.
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 regu-
larly, 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 vi-
brates badly stop the machine and take it to a service dealer.
9. NEVER use a “pressure washer” to clean your auger. Water can pen-
etrate 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.

SPARK PLUG
1. 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.
2. 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 12/15Nm.
FUEL FILTER
1. A clogged fuel filter can cause lack of power and poor pickup. Check
the fuel filter every 15 use hours.
2. 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.

STORAGE
1. Clean the outside of the machine, drive axle, shield and nylon cutting
head.
2. 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 1 teaspoon of clean 2-cycle oil into the combustion chamber. Slow-
ly 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.
