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 500 Series 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 18.
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.
NOTE: DO NOT remove the shroud as you could disconnect
or loosen the wire connecting the OFF switch to the engine
making it inoperable.
Using the hole in the shroud for easy access, remove the
air filter screw.
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 motor oil (SAE 30) 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.
