Service Instructions
Heavy Dust Conditions

Inspect the New Filter for Damage
Inspect the new filter carefully, paying attention to
the inside of the open end, which is the
sealing area.
NEVER install a damaged filter.
A new Donaldson radial seal filter may
have a dry lubricant on the seal to aid
installation.

Insert the New
Radial Seal Filter Properly
If you’re servicing the safety filter, this should be seated into
position before installing the primary filter.
Insert the new filter carefully. Seat
the filter by hand, making certain it is
completely into the air cleaner housing
before securing the cover in place.
The critical sealing area will stretch
slightly, adjust itself and distribute the sealing pressure evenly.
To complete a tight seal, apply pressure by hand at the outer rim of
the filter, not the flexible center. Avoid pushing on the center of the
urethane end cap. No cover pressure is required to hold the seal.
NEVER use the service cover to push the filter into place! Using the
cover to push the filter in could cause damage to the housing, cover
fasteners and will void the warranty.
If the service cover hits the filter before it is fully in place, remove
the cover and push the filter (by hand) further into the air cleaner
and try again. The cover should go on with no extra force.
Once the filter is in place, secure the service cover.

Check Connectors for Tight Fit
Make sure that all mounting bands, clamps, bolts, and connections
in the entire air cleaner system are tight. Check for holes in piping
and repair if needed. Any leaks in your intake piping will send dust
directly to the engine!
1
Remove the Filter
Unfasten or unlatch the service cover.
Because the filter fits
tightly over the outlet
tube to create the critical
seal, there will be some
initial resistance, similar to breaking the seal on
a jar. Gently move the end of the filter back and
forth to break the seal then rotate while pulling
straight out. Avoid knocking the filter against the
housing.
If your air cleaner has a safety filter, replace it every third primary
filer change. Remove the safety filter as you would the primary
filter. Make sure you cover the air cleaner outlet tube to avoid any
unfiltered contaminant dropping into the engine.
Clean Both Surfaces of the Outlet Tube
2
and Check the Vacuator™ Valve
Use a clean cloth to wipe the filter sealing surface and the inside of
the outlet tube. Contaminant on the sealing surface could hinder an
effective seal and cause leakage. Make sure that all contaminant
is removed before the new filter is inserted. Dirt accidently
transferred to the inside of the outlet tube will reach the engine
and cause wear. Engine manufacturers say that it takes only a few
grams of dirt to “dust” an engine! Be careful not to damage the
sealing area on the tube.
If your air cleaner is equipped with a Vacuator Valve
Visually check and physically squeeze to make sure the
valve is flexible and not inverted, damaged or plugged.
Inspect the Old
3
Filter for Leak Clues
Visually inspect the old filter for any signs
of leaks. A streak of dust on the clean side
of the filter is a telltale sign. Remove any
cause of leaks before installing new filter.
Wipe both
sides of the
outlet tube
clean.
Outer edge of the
outlet tube
Inner edge of the
outlet tube
NEVER use the service cover to
push the filter into place! Using
the cover to push the filter in could
cause damage to the housing, cover
fasteners and will void the warranty.
Caution
Rotate the
filter while
pulling
straight out.
