7. Once the inspection has been performed, install
the new secondary filter element into the enclosure
as found upon disassembly. (fig. 4-39)
8. Install the primary element by sliding it into place
in the enclosure as found upon disassembly.
9. Install and secure the cover by sliding it into place
and positioning the band over the retaining lip.
Then turn the tension screw clockwise until tight.
Gently wiggle the cover to make sure it is secure.
To clean your primary filter element:
1. Remove loose dirt from the filter element with com-
pressed air or water hose.
Compressed air: 100 P.S.I. max. 1/8" diameter
nozzle at least 2" away from filter.
Water: 40 P.S.I. max. without nozzle.
2. Soak the filter in a non-sudsing 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 remaining detergent.
4. Allow the filter to dry completely before re-installing
it into the machine.
NOTICE
Do not use any heat source other than warm air at
less than 160°F to dry the filter.
Do not clean air filter elements while engine war-
ranty is in effect. During the warranty period, ASV
recommends replacing air filter elements instead
of cleaning them. Heavy-duty air filter manufactur-
ers will not warrant the air filter once it has been
cleaned.

Fuel Filter

The fuel filter removes contaminants from the fuel as it
enters the engine for combustion. Over time the filter
can become plugged and cause the engine to lose
power, run roughly or fail to start. The fuel filter should
be changed every 500 hours or more often if needed
to prevent these conditions from occurring.
To change the fuel filter:
1. Clean the outside of the filter assembly thoroughly
to reduce the chances of contaminants being intro
duced into the fuel system.
2. Twist the water separator catch bowl (A) counter
clockwise (when viewed from the bottom) and
remove it from the assembly. Take care not to lose
the o-ring that seals it to the filter base.
3. Twist the upper lock ring (B) counter clockwise
(when viewed from the bottom) and remove it from
the assembly.
4. Slide the filter (C) downward to remove it. Note the
position of the raised tabs on the upper portion of
the filter to simplify reassembly.
5. Install the new filter element into the assembly by
reversing steps 2-4.

Water Separator

The water separator removes water from the fuel sup-
ply as the engine runs. Drain the water separator daily
to maintain proper function.
To drain the water separator:
1. Loosen the black screw on the bottom of the
separator.
2. Re-tighten the screw after the water has been
drained from the catch bowl.
