DRIVE ADJUSTMENTS
,&
CAUTION: Stop the engine, put
the steering control levers in the
park position and remove the key

AIR CLEANER SERVICE
(Figure 24)
CAUTION: Touching hot surfaces
can burn skin. The engine and
components will be hot after the
unit has been running. Allow the
engine and components to cool
before servicing the unit.
IMPORTANT: To prevent excessive engine
wear, do not run the engine without the air
cleaner installed.
IMPORTANT: The engine is air cooled and
requires a large amount of air intake when
running. Reduced air intake can cause
overheating. Always keep air intake screen
and cooling fins clean. Always keep the
covers and screens in place.
Figure 24
The Unloader Valve (1) will allow for the
removal of fine dirt and dust from the canister
body (3) without disassembly. While in
operation, this valve will suck closed at 1/3 to
1/2 throttle.
With the engine shut off, squeeze the
valve by hand to release dust and
debris.
In very dusty operating conditions, the
valve may have to be opened every 2
to 3 hours.
Remove the air cleaner cover and make a
general inspection of the entire assembly. If it
is unusually dirty or if dirt build-up is easily
visible on the inside of the canister body, the
entire assembly, including the inlet hose,
must be removed from the carburetor and
engine.
With the air cleaner removed from the engine,
and with the cartridges and gaskets removed,
wash the hard parts with cleaning solvent and
blow them dry with compressed air. DO NOT
wash the air cleaner cartridges.
NOTE: If canister gaskets are broken or
missing, BOTH air cleaner elements MUST
be replaced.
Inspect and clean the primary air cleaner
cartridge (5) assembly every 25 hours.
Replace the paper element yearly or every
250 hours, whichever comes first.
The outer cartridge is cleaned by rolling and
"tapping" it on a hard surface. If the paper
pleats are punctured or torn, the element
must be replaced.
