Spraying Technique
IMpORTANT: Proper spraying technique
is ESSENTIAL to achieve good results.
1. First, prepare the Spray Gun
according to the instructions under
Spray Gun Setup Adjustment on page 11.
2. Keep the Spray Gun upright and
at a right angle to the workpiece -
See Figure G and Figure H.

Do not pivot your wrist
or wave the gun like a
fan towards the wall.
Move your arm, not just your wrist.
Point gun directly towards the surface and
maintain an even, steady distance and speed.

3. Using two hands, one to steady the
Paint Cup and the other to operate the
Spray Gun, aim Nozzle at the workpiece.
CAUTION: DO NOT STOp WHEN SpRAYING.
Spraying materials will start to set and dry as soon
as they come in contact with the air. They will
cause a permanent clog if not cleared immediately.
If discontinuing spraying for more than half
an hour, turn off the air supply, disconnect
Paint Cup from Gun Body, and thoroughly
rinse Cup and Gun Body following the paint
manufacturer’s recommendations for cleaning,
solvent type, and disposing of used solvent.
4. Pull Trigger slowly and move Spray Gun
in parallel strokes to the workpiece.
Keep the distance from the workpiece
at about 14″ to 16″, depending on the
flow adjustment and the paint.
5. To avoid paint build up, start moving the
Spray Gun before squeezing the Trigger.
When finished with the stroke,
release the Trigger while still moving
the Spray Gun - see Figure I. Doing this
will produce a smoother finish. Do not stop
moving the Spray Gun while spraying.
If the Spray Gun stops even briefly
while spraying the paint will build up
and run down the workpiece.

Note: The stroke speed, the Fluid Knob
adjustment, and the distance from the workpiece
will determine how much paint is being applied.
Apply two thin coats rather than one thick coat.
CAUTION! Air hose fittings may get hot.
Allow fittings to cool before disconnecting,
or wear gloves to prevent burns.
6. To prevent accidents, release Trigger, detach
air supply, safely discharge any residual air
pressure, and again release Trigger after use.
7. Clean Spray Gun thoroughly immediately
after EVERY use, according to
instructions on the following pages.
