General Operating Instructions
1. Start the compressor, allowing it to
come up to the proper pressure for
the tool.
2. Wipe off any lubricant that may have
been applied from prior use. The
Spray Gun can now be tested.
3. Fill the Cup (31) with the appropriate
amount of paint (up to 3/4 full) of
properly prepared material (see
section on “Preparation”.
4. After the compressor cycles off at the
proper pressure level, connect the air
hose to the Air Inlet Coupling (20).
5. Attach the Cup (31) to the tool using
the Cup Mounting Yoke (33) and
secure with the Cup Locking Lever
(32).
6. If the tool requires more force to
accomplish the task, verify that the
tool receives sufficient, unobstructed
airflow (CFM) and increase the
pressure (PSI) output of the regulator
up to but not beyond, the maximum
air pressure rating of this tool.
CAUTION! TO PREVENT TOOL
AND ACCESSORY FAILURE,
RESULTING IN INJURY:
Do not exceed the tool’s maximum
air pressure rating.
If the tool still does not have sufficient
force at maximum pressure but the
material being sprayed has proper
viscosity, then a larger tool may be
required.
7. To prevent accidents, turn off the
tool, detach the air supply, safely
discharge any residual air pressure in
the tool, and/or turn the switch to its
off position after use. Clean external
surfaces of the tool with clean, dry
cloth. Then store the tool indoors out
of children’s reach.
8. Change Fan Direction.
a. Loosen the Air Ring (2) and turn the
Air Cap (1) to change spray pattern
between horizontal and vertical.
9. Pattern Adjustment. (Never exceed
maximum inlet pressure of 115 PSI.)
a. To reduce air pressure when neces-
sary, adjust the air compressor’s
pressure regulator.
b. To change between patterns, adjust
the Pattern Control Knob (10). Turn
counterclockwise (all the way open),
to flatten the pattern. Turn clockwise
for a round pattern.
10. For best service you should incorpo-
rate a regulator and in-line filter, as
shown in the diagram above. Hoses,
couplers, regulators, and filters are all
available at Harbor Freight Tools.
Note: Compressor pumps discharge
condensed water, oil, or other con-
taminants along with the compressed
air. Condensation causes “fish eyes”
to appear in paint patterns. To avoid
this problem, install water/oil removal
filters and controls (not included) as
close to the Spray Gun as possible.
If run through the Spray Gun, water
or oil will cause damage.
11. You will need to prepare a 1/4" air
connector (sold separately) to con-
nect to the air inlet on the Spray Gun.
First, wrap the 1/4" air connector (not
included) with pipe thread seal tape
before threading it into the Air Inlet
(20). Connect the 3/8" ID air source
hose to the Spray Gun.
12. Set the air pressure on your com-
pressor to 60 PSI. Do not exceed the
maximum operating air pressure of
115 PSI.
13. Check the air connections for leaks.
