Engine Air Filter
Refer to Figure 5-13:
A specially designed dry filter is standard equipment and
supplies clean combustion air to the engine. Perform
engine air filter maintenance per the Engine Operator’s
Manual and “Maintenance Schedule” on page 34.
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” on this page.
5. Install new Inner element into the new outer element
as shown in Figure 5-13.
6. Install new outer filter element by inserting the open
end in the canister first.
IMPORTANT: 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 to canister
such as placing an object in front of the air intake
opening.

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. Locate and repair source of ingested
dirt.
10. Never operate a machine without an air filter
installed.

the canister to make certain it drains water away
from the filter elements properly.
Burp Valve
Refer to Figure 5-14:
The burp valve is a highly important part of your dust filter. It opens and shuts expelling collected dust and water as
the engine’s vacuum pressure pulsates. It also dumps dust collected in the filter canister when the engine stops
running. If the burp valve is damaged, dust that would normally be discharged from the canister can collect on the
filter element causing its life to be shortened. Replace the burp valve if it is open, cracked, torn, or missing.
