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 machine, shut off engine, wait for all moving parts to stop, and discon- nect spark plug wire and move it away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.
NOTE: The Briggs and Stratton Q45™ engine has a separate warranty found in the engine manual (included with this product).
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 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 16.
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.
Remove the shroud screws holding the shroud in place as shown in figure 16.
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 SAE 30 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.
Reinstall the air filter cover and tighten securely using the air filter screw.
Retighten the shroud screws.
