MAINTENANCE
WARNING:
When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING:
Always wear safety goggles or safety glasses with
side shields during power tool operation or when
blowing dust. If operation is dusty, also wear a
dust mask.
WARNING:
Before inspecting, cleaning or servicing the ma-
chine, shut off engine, wait for all moving parts to
stop, and disconnect spark plug wire and move
it away from spark plug. Failure to follow these
instructions can result in serious personal injury or
property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petro-
leum-based products, penetrating oils, etc., come
in contact with plastic parts. Chemicals can dam-
age, weaken or destroy plastic which may result in
serious personal injury.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an authorized service center.
Before running the engine, perform the following pre-
operation steps:
Check that all bolts, nuts, etc., are securely tightened.
Make sure the air filter is clean.
Check both the engine oil level and the fuel tank level;
refill as needed.
Inspect the work area for hazards.
If there is excessive noise or vibration, stop the unit
immediately.
CLEANING THE AIR FILTER
See Figure 20.
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the engine. Check
the air filter monthly. For best performance, replace the air
filter at least once a year.
Push the tab on the air filter cover to open, then remove
the air filter cover.
Lift the edge of the air filter carefully and pull it out.
Wash the air filter with warm, soapy water.
Rinse and squeeze to dry.
Put small amount of motor oil (SAE 30, orSAE 10W30) on
the filter sponge. Squeeze out the excess oil then reinstall
the air filter.
NOTE:
Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
Reinstall the air filter cover.
