Primary Element Cleaning
Procedure
1.
Remove loose dirt from the fil-
ter element with compressed
air or a water hose.
Compressed air: 100 P.S.I.
maximum with a 1/8” nozzle at
least 2” away from the the filter.
Water: 40 P.S.I. maximum with-
out a nozzle.
2. Soak the filter in a non suds-
ing detergent solution for at
least 15 minutes moving it
gently through the solution to
further clean the element.
Never soak for more than 24
hours.
3. Rinse the filter thoroughly
with a gentle stream of water
to remove all dirt and remain-
ing detergent.
4. Allow the filter to dry com-
pletely before reinstalling it
into the machine.
Fuel Filter
The fuel filter removes contami-
nants from the fuel as it enters
the engine for combustion. Over
time, the filter can become
plugged and may cause the
engine to lose power, run rough-
ly or fail to start. The fuel filter
should be replaced every 500
hours or more often as neces-
sary to prevent these conditions
from occurring.
To change the filter:
1.
Thoroughly clean the outside
of the filter assembly to
reduce the chance of contam-
inants being introduced into
the fuel system.
2. Loosen the retaining bolt (D)
then remove the filter element
(E) from the filter head and
dispose according to local
mandates and regulations.
3. Reinstall the filter assembly
by reversing step 2.
Do not use any heat source
other than warm air at less
than 160° F to dry the filter.
CAUTION
Do not clean the air filter ele-
ments while the engine warran-
ty is in effect. During the war-
ranty period, ASV recommends
replacing the elements instead
of cleaning them. Heavy- duty
air filter manufacturers will not
warrant the air filter once it has
been cleaned.
