MAINTENANCE
Auger Maintenance
1. The gear case has grease installed at the factory. It is
recommended that once a year, the gear case be split
and the grease level checked. Add grease only if level of
grease is below top of the gears.
DO NOT OVERFILL.
2. Keep all screws, nuts, and bolts tight.
3. For cold weather operation, store the unit in a cool
environment. Transferring the unit from a warm
place to a cold place can cause a build up of harmful
condensation.
4. If blade performance decreases, turn unit off and
disconnect spark plug wire. Carefully inspect cutting
edge of the blade for any signs of wear. If blades
show any of these signs, they need to be sharpened or
replaced.
Engine Maintenance
Cooling Fins
Cooling fins, air inlets and linkages must be free from any
debris before each use.
Air Filter
Never run engine without air filter properly installed.
Added wear and engine failure may occur if air filter is not
installed. Service air filter every 3 months or after 20 hours of
operation. Clean filter daily in extremely dusty conditions.
Steps for Cleaning Air Filter
1. Wash in warm water with mild soap until dirt and debris
are removed. Press filter when washing, do not twist.
2. Rinse in warm water until soap and dirt are removed.
3. Dry filter by wrapping in a clean cloth and pressing filter
until it is dry.
4. Apply oil to the entire filter.
5. Remove excess oil.
6. Attach the filter and air cleaner cover to the engine.
Spark Plug
The recommended spark plug is a NGK BM6A which cross
references to a Champion CJ8.
1. Check spark plug after every 50 hours of operation.
2. Disconnect the spark plug cap, and clean any debris
from around the spark plug area.
3. Remove spark plug and replace if any of the following
occur; pitted electrodes, burned electrodes, cracked
porcelain, or deposits around electrodes.
4. After analysis, seat spark plug and tighten with spark
plug wrench.
•
Reinstall original spark plug, tighten additional 1/2 turn.
•
Installing new spark plug, adjust spark plug gap to .030”
and tighten additional 1/8 – 1/4 turn .
Transporting Your Earth Auger
1. Never transport engine inside an enclosed space or
vehicle. Fuel or fuel vapours may ignite causing serious
injury or death.
2. If fuel is present in the fuel tank, transport in an open
vehicle in an upright position.
3. If an enclosed vehicle must be used, remove fuel into an
approved fuel container. DO NOT siphon by mouth.
4. Run engine to use up the fuel in the carburettor and
fuel tank. Always run engine in a well ventilated area.
5. Wipe away any spilled fuel from engine and auger.
Allow to dry.
To prevent accidental starting:
Avoid injury! Temperature of muffler and nearby areas
may exceed 65°C, avoid these areas.
Avoid injury! Check auger often for loose nuts and
bolts. Keep these items tightened.
Avoid injury! Never store engine with fuel in the tank
inside a building. Potential sparks may ignite fuel or
fuel vapours.
Avoid injury! An adult must always do maintenance
and repair on engine and auger.
Avoid injury! Engine must be shut-off, cool, and spark
plug wire removed before any repair or maintenance
can be done.
CAUTION
NOTE: Loose spark plug may overheat and damage
engine. Over tightened spark plug may damage
threads in the cylinder head.
Carburettor: Never tamper with factory setting of the
carburettor.
