5. Start the air compressor and set
the regulator to needed pressure.
Do not exceed maximum air pressure.
6. Test the consistency by spraying
on a piece of scrap material.
7. Adjust the mixture, if necessary, according
to the coating manufacturer’s directions.
8. If the coating is the proper consistency,
but is still not spraying properly,
adjustments may be made by:
a. Adjusting Air Pressure.
b. Adjusting Fluid Control Knob.
c. Changing the Nozzle.
Fluid Adjustment
9. Turn the Fluid Control Knob
clockwise until it is fully closed.
10. After setting up a piece of scrap material,
squeeze the Trigger in short bursts
while turning the Fluid Control Knob
counterclockwise to set the amount of fluid.
If spray is too fine:
Reduce the air pressure or allow
more coating to come out by
opening the Fluid Control Knob.
If spray is too thick (globs of coating):
Close the Fluid Control Knob slowly,
checking the pattern after each adjustment.
11. When the proper consistency has been
achieved, see Spraying Technique below.
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 10.
2. Fill the Hopper to no more than 3/4 full.
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
Hopper from Gun Body and thoroughly
rinse Hopper and Gun Body with solvent.
3. Experiment on scrap material to determine
proper Nozzle angle, distance from
the surface, and spraying pattern.
4. Use two hands, one to steady the Hopper
and the other to operate the Spray Gun.
5. Squeeze the Trigger to start spraying.
Note: For continuous spraying,
use the Trigger Lock.
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.
