Service Air Cleaner

Your engine will not run properly and may be
damaged if you run it with a dirty air cleaner.
Service the air cleaner once every 100 hours of
operation or once each year, whichever comes first.
Service more often if operating under dirty or dusty
conditions. Replacements are available at your local
Sears service center.
To service the air cleaner, follow these steps:
Remove screws and lift cover.
Carefully remove pre-cleaner and cartridge
assembly.
After servicing pre-cleaner and cartridge, assemble
pre-cleaner on cartridge.
Install pre-cleaner/cartridge in base.

Carburetor

If you think your carburetor needs adjusting, see your

arrester. In some areas, it is illegal to operate an
engine without a spark arrester. Check local laws and
regulations. A spark arrestor is available from your
nearest Sears service center. For the part number call

The spark arrester must be serviced every 50 hours to
keep it functioning as designed.
If the engine has been running, the muffler will be very
hot. Allow the muffler to cool before servicing the
spark arrester.

inspection.
