spray pattern and possibly damaging the filter.
This filter must be cleaned daily. If the material being
used is old or contains hardened particles, then the filter
should be cleaned approximately every 4 hours.
If the filter is not cleaned at the proper time, it will plug
from the top down. When there is about 1 inch of filter
that isn't plugged, the heavy flow of paint will blow pin
holes in the filter. Holes in the filter will allow unwanted
particles to get into the spray tip, causing the spray tip to
clog.

Cleaning the filter during the painting
process
1. Turn the pressure control knob counterclockwise to
the minimum setting and turn the PRIME/SPRAY
knob to PRIME ( ). This will bleed off the pressure
in the paint hose and filter. Trigger the gun to be
sure that the pressure is gone. Refer to the PRES-
SURE RELIEF PROCEDURE section.
2. Lock the spray gun by turning the gun safety switch
parallel to the gun body.
3. Remove the spray gun from the hose using two
adjustable wrenches.
4. Unclip the bottom of the knuckle guard from the filter
housing by pulling outward from the filter housing.
5. Unscrew the filter housing using an adjustable
wrench on the nut at the bottom of the housing.
6. Remove the filter. Do not lose the spring and the
sealing washer located in the bottom of the filter
housing.
7. Clean the filter thoroughly or replace it with a new
filter. To clean the filter, rinse it thoroughly in water
or the type of solvent appropriate to the paint you
are using. If this is not sufficient, use a natural or
nylon bristle brush dipped in water or the appropri-
ate solvent. Do not use a wire brush or any sharp
instrument on the filter.
8. Insert the top of the filter into the gun body under
the tip of the spray gun.

Cleaning the suction set screen
The screen at the bottom of the suction set may also
need cleaning. Check it every time you change paint
buckets. Remove the screen by pulling it out of the
retainer with a plier. Clean the screen with water or
solvent and a soft-bristle brush.
