CLEAN UP
Cleaning the Spray Gun Filter
The spray gun includes a filter to catch
dirt particles before they reach the spray
tip. If this filter becomes clogged or
obstructed it will reduce the flow of
paint, changing the spray pattern and
possibly damaging the filter.
Clean the filter with a brush. Never
poke the filter with a sharp instrument.
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.
Changing the
Filter
1. Unscrew fitting #6 from
the gun, making sure not
to lose the spring #5.
Remove the old filter.
2. Slide the new filter,
tapered end first, into the
gun housing.
3. Replace the spring #5 and the fitting #6. Tighten with a
wrench.
NOTE: The tapered end of the filter must be loaded
properly into the gun. Improper assembly
will result in a plugged tip.

Paint tailing pattern
NOTE: The pressure control dial should be set at the
maximum setting (+) in most cases when
using thicker viscosity materials such as latex
paints. You may have to lower the pressure
setting (-) when using thinner viscosity
materials such as stains. If the pressure is
set too high, you will over atomize and waste
paint. If the pressure is set too low, tailing
will appear or the paint will spatter out in
gobs rather than a fine spray.

Unclogging the Spray Tip
Do not attempt to unclog or clean the tip with your finger.
Do not use a needle or other sharp pointed instrument to
clean the tip. The hard tungsten carbide is brittle and can
be chipped.
The spray gun is equipped with a reversible tip which allows
you to blow out any particles of old paint or other contaminants
that may obstruct the paint flow through the tip. If the spray
pattern becomes distorted or stops completely while the gun is
triggered, follow these steps:
1. Release the trigger and lock the gun off.
2. Rotate the reversible tip cylinder arrow
180° so that the point of the arrow is
toward the rear of the gun.
3. Unlock the gun and squeeze the trigger,
pointing the gun at a scrap piece of
wood or cardboard. This allows pressure in the spray
hose to blow out the obstruction. When the nozzle is
clean, paint will come out in a straight, high pressure
stream.
4. Release the trigger and lock the gun off.
5. Reverse the tip so the arrow points forward again.
6. Unlock the gun and resume spraying.
Cleaning the Spray Tip
1. Turn the PRIME/SPRAY knob to PRIME. This will bleed
off the pressure in the spray hose and filter. Trigger the
gun to be sure that the pressure is gone. Refer to the
PRESSURE RELIEF PROCEDURE section.
2. Lock the spray gun off.
3. Remove the spray tip assembly from the gun with a
wrench.
4. Turn the spray tip so that the arrow tab is perpendicular to
the spray guard and pull the tip out.
5. Push the seal and washer out the back end of the tip
guard.
6. Wash all the tip assembly parts with soapy water or an
appropriate solvent.
NOTE: If spraying with latex paint, use warm soapy
water for cleaning. If using oil or alkyd-based
paints, use mineral spirits of paint thinner.
Refer to the paint manufacturer’s instructions
for specific recommendations.
NOTE: It is sometimes necessary to relieve pump
pressure by turning the PRIME/SPRAY knob to
PRIME before rotating the reversible tip.
NOTE: If the spray tip remains clogged, follow the
Cleaning the Spray Tip procedure.
