If The Spray Tip Becomes Clogged; Cleaning The Spray Gun Filter; Cleaning The Suction Set Screen - WAGNER High-performance Airless Sprayer Owner's Manual

6. Trigger the spray gun to bleed air out of the hose.
7. When paint reaches the spray tip, spray a test area to
check the spray pattern.
8. Use the lowest pressure setting necessary to get a good
spray pattern. If the pressure is set too high, the spray
pattern will be too light. If the pressure is set too low,
tailing will appear or the paint will spatter out in gobs
rather than in a fine spray.

If the Spray Tip Becomes Clogged

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 on, follow these steps:
1. Release the trigger and lock the gun by turning the gun
trigger lock so that it is parallel to the gun body.
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 trigger and squeeze it open, pointing the gun
at a scrap piece of wood or cardboard. This allows
pressure in the paint 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 re-lock it.
5. Reverse the tip so the arrow points forward again.
6. Unlock the trigger and resume spraying.

Cleaning the Spray Gun Filter

The spray gun includes a filter to catch 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.
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 Filter During Painting Process
Be sure to follow the pressure relief procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray tips, or preparing for cleanup.
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 PRESSURE RELIEF PROCEDURE section.
2. Lock the spray gun by turning the gun trigger lock 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 appropriate 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.
Filter Housing
9. Replace the spring and sealing washer into the base of
the filter housing.
10. Slide the filter housing over the filter and use a wrench to
tighten it securely.
11. Clip the knuckle guard to the base of the filter housing.
12. Attach the hose to the gun. Use two adjustable wrenches
to tighten it securely.
13. Turn the PRIME/SPRAY knob to SPRAY. Increase the
Filter top
pressure to its previous setting and resume spraying.

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
Pin Hole
retainer with a plier. Clean the screen with
water or solvent and a soft-bristle brush.
