SPRAYING TECHNIQUE

SPRAYING TECHNIQUE
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.
A
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.
B
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
i
the spray jet – increase the operating pressure or
dilute the coating material.

CLEANING A CLOGGED TIP
If the spray pattern becomes distorted or stops
i
completely while pulling the trigger, perform the
steps below.
1.
Move the PRIME/SPRAY valve down to the PRIME position.
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.
3.
Move the PRIME/SPRAY valve up to the SPRAY position.
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.
