O
perators, keep a close eye on the air cleaner indicator right next to your dozer’s air
flter element canister. IF the indicator moves to red, it’s cleaning time.
Open the canister and pull out the primary air flter. Use an air hose From a nearby
tactical vehicle to blow low-pressure air (30 psi or less) From the inside out. Never bang
the flter on a rock or hard surFace like the dozer’s track. That just damages the flter.
You should replace the primary air flter element once a year or aFter six cleanings,
whichever comes frst.
When the dozer’s secondary flter
becomes
clogged,
have
your
unit
mechanic replace it.
How do you tell if it’s clogged?
AFter
installing a clean or new primary flter
element, watch the air cleaner indicator.
IF it moves into the red zone when you
start your dozer, the secondary flter’s
clogged. Black exhaust smoke is another
sign oF a clogged flter.
Make the Seal Tight
With the flter elements installed,
make sure the canister lid closes
completely. That lid needs a tight
seal to keep out the dirt and sand that
can ruin your dozer’s turbocharger
and engine.
The lid has a recessed lip with a
raised mark on its outer cover. Make
sure this area points toward the Front
oF the vehicle. That way the primary
flter element fts tight against the lid
with a good seal.

help keep the rust
