Pressure Relief Procedure

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 off the sprayer by moving the

ON/OFF switch to the OFF position.

3. Set the pressure to minimum by turning

the pressure control knob fully
counterclockwise.

4. Unlock the gun by turning the gun trigger

lock to the unlocked position.

5. 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.

6. Trigger the gun to remove any

pressure that may still be in the hose.

7. Lock the gun by turning the gun trigger lock to the locked

position.

8. Move the PRIME/SPRAY valve down to the

PRIME position.

Spraying

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.

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 12 to 14 inches (30 to 35 cm).
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.

Avoid arcing or holding the gun at an angle. This will result in
an uneven finish.

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%.

For corners and edges, split the
center of the spray pattern on the
corner or edge and spray
vertically so that both adjoining
sections receive approximately
even amounts of paint.

When spraying with a shield, hold it firmly against the surface.
Angle the spray gun slightly away from the shield and toward
the surface. This will prevent paint from being forced
underneath.

Shrubs next to houses should be tied back and covered with a
canvas cloth.  The cloth should be removed as soon as possible.
gun extensions are extremely helpful in these situations.

Nearby objects such as automobiles, outdoor furniture, etc.
should be moved or covered whenever in the vicinity of a
spray job.  Be careful of any other surrounding objects that
could be damaged by overspray.
