Engine Air Filter
Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual.
A specially designed dry filter is standard equipment on
these mowers and supplies clean combustion air to the
engine. Figure 5-3 & Figure 5-5
Some of these mowers are equipped with a safety filter.
The filter element slides over the safety filter. Figure 5-4 &
Figure 5-6
The safety filter does not require servicing unless it
becomes contaminated with dirt or moisture.
Recommended Service Procedure
1. Release clamps and remove element. Clean the air
cleaner canister with a damp cloth.
2. Before installing a new element, inspect it by placing a
bright light inside and rotating the element slowly,
looking for any holes or tears in the paper. Also check
gaskets for cuts or tears. Do not attempt to use a
damaged element which will allow abrasive particles
to enter the engine.
3. Kawasaki engines — Reinstall the dust cap. Make sure
it seals all the way around the air cleaner canister,
then tighten the clamps. Figure 5-7
Kohler engines — Reinstall the top of the canister
housing. Make sure it seals all the way around the
lower part of the housing, then tighten the clamps.
Figure 5-8
4. Kawasaki engines — Check all fittings and clamps
periodically for tightness and inspect hoses for holes
or cracks.
5. Kawasaki engines — Periodically check the intake hose
for signs of ingested dust. Locate and repair the
source of ingested dirt.
6. Never operate the machine without an air filter
installed.
