MAINTENANCE
Use only resistor type spark plugs of the approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.

Muffler

44
Free the engine and silencer of twigs, leaves and excess lubricant
to prevent the risk of fire.
WARNING: Do not operate your earth auger if
the muffler is damaged, missing or modified. An
improperly maintained muffler will increase the risk
of fire and hearing loss.

Gear Housing

There is a grease cap and a plug for filling lubricant on the gear
45
housing (Fig.44). Use a grease gun to fill with grease. This should
be done after every 100 working hours.
CAUTION: The gear housing must not be filled
completely with grease. The grease expands as
the machine heats up during operation. If the gear
housing was completely filled with grease it could
damage the seals and lead to leakage of grease.
WARNING! - Do not change the ratio of the reduction
gearbox. The characteristics of the machine could
change and unforeseen reactions could occur.

Bit Maintenance

Clean (don't use grease solvent) any resin and plant residue from
the bits before and after using the machine.
WARNING: Do not try to sharpen a damaged bit:
change it or take it to a Service Dealer.
Check that the bit is not damaged or distorted.
46
Replace the bit if it is bent or damaged.
Never repair damaged bit by welding, straightening
or modifying the shape.
Always check the drill bit. Check the share (A, Fig.45) and the
starting tip (B) regularly. Sharpen or replace if worm.
