MAINTENANCE

Air Filter

WARNING: Do not clean filter in gasoline or other
flammable solvent to avoid creating a fire hazard or
producing harmful evaporative emissions.
Open air filter cover (A, Fig.38) and check the air filter (G) each
day; shake the filter. Reinstall the air filter. Close the air filter
cover. An used air filter can never be completely cleaned. It is
41
advisable to replace your air filter with a new one after six month
of operation.
CAUTION: Never run the engine without the air filter,
serious damage could result.
Make sure the air filter is correctly placed in the air
filter cover before reassembly.
Always replace damaged filters.
Do not clean a filter with a brush.

Cooling System

42
To keep the working temperature as low as possible the machine
is equipped with a cooling system.
The cooling system consists of:
1. Fins on the flywheel (Fig.41).
2. Cooling fins on the cylinder (Fig.42).
Clean the cooling system with a brush once a week, more often in
demanding conditions. A dirty or blocked cooling system results
in the machine overheating which causes damage to the piston
and cylinder.
WARNING: The coil spring is under tension and
43
could fly apart causing serious injuries. Never try to
disassembly or modify it.
WARNING: Never run the earth auger without all the
parts, securely in place.
Because parts can fracture and pose a danger of
thrown objects, leave repairs to the flywheel and
clutch to trained Servicing Dealers.

Spark Plug

This engine uses a Champion RCJ-7Y with .02" (0.5 mm) electrode
gap (Fig.43). Use an exact replacement and replace every six
months or more frequently, if necessary.
WARNING: Never test the ignition system with ignition
wire connector removed from spark plug or with
unseated spark plug, since uncontained sparking
may cause a fire. A loose connection between spark
plug terminal and ignition wire connector in the boot
may create arcing that could ignite combustible
fumes and cause a fire.
