SPRAYING
Injection hazard. Do not spray without the tip
guard in place. NEVER trigger the gun unless
the tip is completely turned to either the spray
or the unclog position. ALWAYS engage the
gun trigger lock before removing, replacing or
cleaning tip.
A)
The key to a good paint job is an even coating over the
entire surface. Keep your arm moving at a constant speed
and keep the spray gun at a constant distance from the
surface. The best spraying distance is 10-12 inches (25 to
30 cm) between the spray tip and the surface.
25 - 30 cm

B)
Keep the spray gun at right angles to the surface. This
means moving your entire arm back and forth rather than
just flexing your wrist.
Keep the spray gun perpendicular to the surface,
otherwise one end of the pattern will be thicker than the
other.

C)
Trigger gun after starting the stroke. Release the trigger
before ending the stroke. The spray gun should be
moving when the trigger is pulled and released. Overlap
each stroke by about 30%. This will ensure an even
coating.

If very sharp edges result or if there are streaks in
the spray jet – increase the operating pressure or
dilute the coating material.

CLEANING A CLOGGED TIP
i
If the spray pattern becomes distorted or stops
completely while pulling the trigger, perform the
steps below.
1.
Turn the relief valve to PRIME (
circulation).
2.
If the tip clogs, rotate the tip handle 180° until the arrow on
the handle is facing the opposite of the spray direction and
the handle clicks in the reverse position (Fig. 12).
3.
Turn the relief valve to SPRAY (
spray).
4.
Trigger the gun once so that the pressure can blow the
clog out. NEVER use the tip in the reverse position for
more than ONE trigger pull at a time. This procedure can
be repeated until the tip is free of clogging.
The flow from the spray tip is at very high
pressure. Contact with any body part may be
dangerous. Do not place finger on gun outlet.
Do not point the gun at any person. Never
operate the spray gun without the proper tip
guard.
