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:

nCheck that all bolts, nuts, etc., are securely tightened.

nMake sure the air filter is clean.

nCheck both the engine oil level and the fuel tank level; refill as needed.

nInspect the work area for hazards.

nIf there is excessive noise or vibration, stop the unit immediately.

cleaning the air filter

See Figure 23.

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.

nPush the tab on the air filter cover to open, then remove the air filter cover.

nLift the edge of the air filter carefully and pull it out.

nWash the air filter with warm, soapy water.

nRinse and squeeze to dry.

nPut small amount of motor oil (SAE 30 or SAE 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.

nReinstall the air filter cover.
