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, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, 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 a Ryobi Authorized Service Center.

refill as needed.
n �Inspect the work area for hazards.
n �If there is excessive noise or vibration, stop the unit

CLEANING THE AIR FILTER
See Figure 19.
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the engine. Check
the air filter monthly. If working in dusty soil, clean the
air filter after each refueling. For best performance, replace
the air filter at least once a year.
To clean the air filter:
n Remove the cover.
Fig. 19
n Lift the edge of the air filter carefully and pull it out.
n Wash the air filter with warm, soapy water.
n Rinse and squeeze to dry.
n Put small amount of 30 wt. motor oil 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.
n Reinstall the cover.
