AIR CLEANER MAINTENANCE:
*
WARNING: NEVER OPERATE ENGINE WITH AIR CLEANER
ASSEMBLY OR AIR CLEANER CARTRIDGE REMOVED. FIRE
MAY RESULT.
A properly serviced air cleaner protects internal parts of the engine from
dirt and dust particles in the air. If air cleaner instructions are not care-
fully followed, dirt and dust which should be collected in the cleaner
will be drawn into the engine. These particles are highly abrasive and
will cause the piston rings and cylinder bore to wear quickly. As the
rings and cylinder bore become worn, these abrasive particles enter
the crankcase and contaminate the oil, forming an abrasive mixture
which will cause wear on all of the internal moving parts.
The air cleaner on every engine brought in for a check up or repair
should be examined and serviced. If the air cleaner shows signs of
neglect, show it to the customer before cleaning. Instruct the customer
on proper care, to assure long engine life.
Note: Replace air cleaner gaskets and mounting gaskets that are
worn or damaged, to prevent dirt and dust from entering engine
due to improper sealing. Replace bent air cleaner mounting
bracket if necessary.
SERVICE CANISTER AIR CLEANERS:
Clean the air filter element(s) with compressed air every 50 hours or
every season, whichever occurs first. Replace the air filter element(s)
every 500 hours or if damaged (see Figure 1-8).

SERVICE DUAL ELEMENT AIR CLEANERS:

whichever occurs first. Service cartridge every 50 hours or every
season, whichever occurs first (see Figure 1-9).
