Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.

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, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which can result in serious personal injury.

MAINTENANCE

SERVICING THE PRODUCT
Check and tighten all fasteners. If any part is damaged or
lost, repair it or replace it.
CHECKING THE FUEL CAP, TANK, AND LINES
WARNING:
Check for fuel leaks. A leaking fuel cap, tank, or lines
are a fire hazard and must be replaced immediately. If
you find any leaks, correct the problem before using the
product. Failure to do so could result in a fire that could
cause serious personal injury.
The fuel cap contains a non-serviceable filter and check
valve. A clogged fuel filter causes poor engine perfor-
mance. If performance improves when the fuel cap is loos-
ened, the check valve may be faulty or the filter may be
clogged. Replace the fuel cap if necessary.
CLEANING AIR FILTER
See Figure 16.
A wet or dirty air filter can affect the way the engine starts,
performs, and wears. The air filter should be checked and
cleaned after 5 hours of operation. Inspect and clean more
frequently if used in dusty dirty conditions.
For best performance, the air filter should be replaced ev-
ery 25 hours or yearly.
To clean the air filter:
 Loosen the knob on the air filter cover.
 Remove the cover.
 Lift the edge of the air filter carefully and peel it out.
 Wash the air filter with warm, soapy water.
 Rinse and squeeze to dry.
 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.
 Install the air filter cover.
 Tighten knob to secure.
