Electronic Pressure Control Indicators
The following is a description of the electronic pressure control
indicators.
Spraying Technique
The following techniques, if followed, will assure professional
painting results.
Hold the gun perpendicular to the surface and always at equal
distance from the surface. Depending on the type of material,
surface, or desired spray pattern, the gun should be held at a
distance of 30 to 35 cm (12 to 14 inches).
Move the gun either across or up and down the surface at a
steady rate. Moving the gun at a consistent speed conserves
material and provides even coverage. The correct spraying speed
allows a full, wet coat of paint to be applied without runs or sags.
Holding the gun closer to the surface deposits more paint on
the surface and produces a narrower spray pattern. Holding
the gun farther from the surface produces a thinner coat and
wider spray pattern. If runs, sags, or excessive paint occur,
change to a spray tip with a smaller orifice. If there is an
insufficient amount of paint on the surface or you desire to
spray faster, a larger orifice tip should be selected.
Maintain uniform spray stroke action. Spray alternately from
left to right and right to left. Begin movement of the gun before
the trigger is pulled.

Pressure Relief Procedure
WARNING
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. Lock the gun by turning the gun trigger
lock to the locked position.
2. Turn the pressure control knob
counterclockwise to its OFF position.
3. Unlock the gun by turning the gun
trigger lock to the unlocked position.

in locked position.
Avoid arcing or holding the gun at an angle. This will result in
an uneven finish.
Offspray
4. Hold the metal part of the gun firmly to
the side of a metal container to ground
the gun and avoid a build up of static
electricity.
5. Trigger the gun to remove any pressure
that may still be in the hose.
6. Lock the gun by turning the gun trigger lock to the locked
position.
7. Move the PRIME/SPRAY valve down to the PRIME
position.

Spraying
NOTE: When spraying block fillers, mastics, or high
solid coatings, remove the gun filter and the
high pressure filter.
Proper lapping (overlap of spray pattern) is essential to an
even finish. Lap each stroke. If you are spraying horizontally,
aim at the bottom edge of the preceding stroke, so as to lap
the previous pattern by 50%.
Overlap edges
WARNING
POSSIBLE INJECTION HAZARD. Do not spray without the
tip guard in place. Never trigger the gun unless the tip is
in either the spray or the unclog position. Always engage
the gun trigger lock before removing, replacing, or
cleaning tip.
