9.6.1 Engine Maintenance Safety
WARNING!
Never operate the engine indoors. Park the
machine outdoors in a position where the
prevailing winds blow the exhaust away from
you.
Engine exhaust contains carbon monoxide (CO)
that can quickly accumulate to a dangerous
level. Carbon monoxide can cause illness,
unconsciousness, or death.
For more information, see Engine Operation Safety on page
21.
• Remove the wire from the spark plug before servicing the
engine or equipment to prevent the engine from starting.
• Examine the muffler on a regular basis to make sure that
it operates effectively. Repair or replace a worn or leaking
muffler.
• Before storage, replace fuel that contains ethanol with
an alkylate or appropriate engineered fuel to prevent the
buildup of deposits.
• Check the fuel lines and fittings frequently for cracks or
leaks. Replace damaged fuel lines or fittings, if necessary.
• Store fuel away from all wood material.
• Do not check for a spark with the spark plug or spark plug
wire removed.
• Do not touch a hot muffler, cylinder, or fins. Contact can
cause burns.
9.6.2 Engine Air Filter
IMPORTANT! Operating the engine without an air filter, or
with a damaged air filter, can allow dirt to enter the engine,
causing rapid engine wear. This type of damage is not
covered by warranty.
Clean the air filter after every 50 hours of operation or
annually.
A dirty air filter can restrict air flow to the carburetor, reducing
the engine performance. If the engine is operated in very dusty
areas, clean the air filter more often than specified.
1. Loosen the air-filter cover fastener.
2. Remove the cover.
3. Remove the air filter.

with a new air filter.
6. Install the air filter in the engine.
