Owner’s Manual tor complete engine
maintenance guidelines and instructions.

after every 8 operating hours (whichever
comes first). Refer to the Engine
Owner’s Manual for how to check the oil
level.
• Change the engine oil after the first 5
hours of operation, then every 25 hours
thereafter (change more often if operat­
ing in extremely dusty, dirty conditions).

AIR CLEANER MAINTENANCE
The engine air cleaner system filters the
air before it is drawn into the carburetor
for combustion. This air cleaner system
requires regular maintenance for maxi­
mum engine life and performance. Refer
to the Engine Owner’s Manual for engine
air cleaner service information.
IMPORTANT: Service the air cleaner
system more often if used in extremely
dusty conditions.
ENGINE SPARK PLUG
To maintain peak engine efficiency, service
the spark plug every 100 hours, or annu­
ally, as instructed in the Engine Owner’s
Manual.
KEEP ENGINE CLEAN
Check the engine recoil housing, cooling
fins and muffler frequently for debris and
clean daily before running the engine.
Grass, dirt, or wood chips can clog the
rotating screen and the engine air cooling
system and cause overheating. Clean the
muffler area to remove combustible
debris. Use a cloth or brush when clean­
ing. Do not clean with a forceful spray of
water because water could contaminate
the fuel system.
If the engine is equipped with a spark
arrester screen, remove it for cleaning and
inspection. Replace if damaged or
plugged.
A
WARNING
to avoid a fire hazard, keep ieaves,
grass, and other combustihie materiais
away from hot engine and muffler.
CARBURETOR ADJUSTMENT
■»The carburetor has been adjusted at the
factory. It should not need to be reset. If
a black exhaust is noted, check the air
cleaner first. An over-rich mixture is usu­
ally caused by a poorly serviced or
clogged air cleaner element, not an
improperly adjusted carburetor. If read­
justment is necessary, refer to the Engine
Owner’s Manual or contact your local
authorized dealer.
FUEL FILTER
If engine is equipped with a fuel filter,
clean it every 50 hours of operation (see
Engine Owner’s Manual for instructions).
OFF-SEASON STORAGE
When storing the unit for more than 30
days, follow the storage guidelines below
to help ensure that the unit will be in good
condition for future use.
Before storing the unit, stop the engine,
allow the engine to cool and disconnect
the spark plug wire from the spark plug.
• Thoroughly clean the unit.
• Tighten or replace any loose or missing
hardware.
• Sand and touch-up any rusted or
chipped painted surfaces.
• Inspect for missing or damaged parts.
Repair or replace parts as necessary.
• Refer to the Engine Owner’s Manual for
proper engine storage information and
service the engine as instructed. Be sure
to protect the fuel system and carburetor
from fuel gum deposits that can develop
during extended storage.
• Cover the unit with a suitable protective
cover that does not retain moisture.
NOTE; Do not use a plastic cover. A
plastic cover will retain moisture and
promote corrosion.
A

line vapors may reach an open flame or
spark.
