Inspect the old Filter
Inspect the old filter for any signs of leaks. A
streak of dust on the clean side of the filter
is a telltale sign. Eliminate any source of air
leaks before installing the new primary filter.
Inspect the New Filter
Inspect the new filter for any damage that
may have occurred through mishandling.
NEVER install a damaged filter. Visually check
the inside of the open end, which is the
sealing area.
Do not wipe the filter RadialSeal
™
sealing
area. Donaldson RadialSeal
™
filters have
an invisible dry lubricant on the seal to aid
installation.
Insert the New Filter
First, if you’re servicing the safety filter at
this change-out, seat it properly into position
before installing the primary filter. Insert new
filters carefully. Seat the primary filter by
hand, making certain it is inserted completely
into the air cleaner housing. To complete a
tight seal, apply pressure by hand at the outer
rim of the filter, not the flexible center.
No cover pressure is required to hold the
seal in place and you should NEVER use the
service cover to apply pressure. This could
damage the housing and fasteners and void
the warranty. If the service cover presses
against the filter before the cover is fully in
place, remove the cover. With the cover off,
push the filter farther into the air cleaner by
hand and then the cover will go on with no
extra force. Once the filter is in place, secure
the service cover.
For FPG Alexin
™
models, twist the cover to
the right until it stops, then push the yellow
“finger” in to lock.
Check Connectors for tight Fit
Make sure service indicators are reset and in
proper working order. Check that all mounting
bands, clamps, bolts, and connections in the
entire air cleaner system are tight. Check
for holes in piping and repair or replace as
needed. Any leaks in the intake piping will
admit dust directly to the engine. Reset the
filter service indicator.
If you perform filter maintenance service on a schedule versus using service indicators, you may want to
write the service date on the end cap of both filters.
