WARNING: If the SPRAY TIP OR HOSE
IS CLOGGED, Expect material splashing
into the bucket while opening the Priming
Valve. So open the valve very slowly and take
precautions.
SPRAYING -ALL MODELS
Check the quality of the spray pattern on a
piece of scrap material, such as cardboard.
Turn the Pressure Control Knob Clockwise to
increase pressure and counterclockwise to
decrease pressure.
Start with a low spray pressure and slowly
increase the pressure until a good spray
pattern is achieved.
If the pressure is too low, the pattern will
have “tails”, which is a pattern with heavy,
uneven edges. Keep testing and increasing
pressure until a smooth, regular pattern is
achieved. If the pressure is at maximum and
the pattern is still not ideal, either go to a
smaller orice tip or thin the material.
Do not raise the pressure any higher than is
necessary. Operating the sprayer at a higher
than necessary pressure wastes material,
causes early tip wear, and shortens sprayer
life. Excessive pressure can also result in
PRESSURE RELIEF PROCEDURE.
Whenever you stop spraying, even for a
short break, follow the "Pressure Relief
Procedure".
IMPORTANT! To avoid possible serious
body injury, always follow this procedure
whenever the sprayer is shut off, when
checking it, when installing, changing or
cleaning tips, when adding material and
whenever you stop spraying for any reason.
Never leave the unit unattended while in a
pressurized condition.
1. Engage the gun safety latch. (See page
14)
2. Turn the unit off .(See page 3~5)
3. Disengage the gun safety latch and
trigger the gun to relieve residual fluid
pressure. Hold metal part of the gun in
contact with a grounded metal bucket.
Re-engage safety latch.
4. Slowly turn the Priming Valve to the
open (priming) position to relieve any
residual fluid pressure. Then close
priming valve.(See page 2)
