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, 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.
CLEANING THE AIR FILTER

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 8 hours of operation. If working in dusty soil, check the air filter after each refueling.
For best performance, the air filter should be replaced once each year.

nLoosen the knob on the air filter cover.
