Engine Air Filter
A specially designed dry filter is standard equipment and
supplies clean combustion air to the engine.
Internal Type Air Filters
Refer to Figure 5-22 on page 44:
18.5 HP and 23 HP Kawasaki engines are supplied with
internal air filters. Perform engine air filter maintenance
per Engine Operator’s Manual and “Maintenance
Schedule” on page 31.
Canister Type Air Filters
Refer to Figure 5-23 & Figure 5-24:
The 23.5 HP Kawasaki engine is equipped with a canister
air filter mounted above the engine. Perform engine air
filter maintenance per the Engine Operator’s Manual and
“Maintenance Schedule” on page 31.
1. Replace filter element every 200 hours or every year,
(whichever comes first). Service more frequently
when used in dusty conditions.
2. Release retaining clips and remove filter element.
Clean canister with a damp cloth.
3. Before installing a new filter element, inspect it by
placing a bright light inside and rotate 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.
4. Inspect burp valve. Replace burp valve if it is
cracked, torn, stays open, or is missing. See also
“Burp Valve Information” on page 46.
5. Install new inner element into the new outer element
as shown in Figure 5-24.
6. Install new outer filter element by inserting the open
end in the canister first.
7. Reinstall canister cap with burp valve positioned
below the canister. Make sure it seals all around the
canister before latching retaining clips.
8. Check all fittings and clamps periodically for
tightness. Inspect hoses for holes or cracks.
9. Periodically check engine intake hose for signs of
ingested dust. Repair source of ingested dirt.
10. Never operate mower without an air filter installed.
NOTE: Do not operate engine with a damaged air filter
or without air filter elements. Dirt will enter engine
causing dust induced engine damage.
IMPORTANT: Do not block air intake such as setting
an object in front of the air intake opening.
IMPORTANT: Burp valve must be positioned below
the canister to make certain it drains water away
from the filter elements properly.
