2. Do not allow people, mobile equipment or vehicles to pass over the

unprotected air hose. Position the air hose away from high traffic

areas, in a reinforced conduit or place planks on both sides of the air

hose to create a protective trench.

3. Prevent damage to the air hose by observing the following:

a. Never carry the tool by the air hose.

b. Keep the air hose behind the tool and out of the tool's work path.

c. Keep the air hose away from heat, oil, sharp edges or moving parts.

d. Do not wrap the air hose around the tool as sharp edges may pierce

or crack the air hose. Gently coil the hose and either hang on a hook

or fasten with a device to keep hose together when storing.

4. A damaged or disconnected air hose under pressure may whip around and

inflict personal injury or damage the work area. Secure the compressor's

air hose to a fixed or permanent structure with clamps or cable ties.

UNPACKING

WARNING! Do not operate the tool if any part is missing. Replace the

missing part before operating. Failure to do so could result in a

malfunction and personal injury.

Make sure that all items in the contents are included.

Contents: • Paint Gun • Filter • Brush • Paint Cup • Cup Lid

ASSEMBLY & INSTALLATION

Numbered references in parenthesis (#1) refer to the included Parts List.

INSTALL AIR COUPLER PLUG

Prepare a standard 1/4 in. NPT coupler plug (sold separately) for use with

your tool.

1. Wrap the external threads of the coupler plug with sealant tape.

a. Wrap tape in a clockwise direction so it will not unravel.

b. Do not tape all the threads. Leave several leading threads

unwrapped for easier alignment.

8870685 HVLP Gravity Paint Gun V4.0

8 For technical questions call 1-800-665-8685

2. Screw the coupler plug into the tool's air inlet and tighten with a

wrench until snug.

3. Run the compressor at a low volume and check the connection for air

leaks. Do not use the tool until all air leaks are repaired or the faulty

component is replaced.

IMPORTANT! Vibration may cause failure if a quick coupler is connected

directly to the air tool. To overcome this, connect a leader hose to the

tool. A quick coupler may then be used to connect the leader hose to the

air line hose.

OPERATION

Proper handling of the spray gun will achieve the desired paint coating. The

recommended paint viscosity will vary according to the paint’s properties

and the painting conditions like the temperature or humidity. Read the paint

instructions before spraying.

HOW TO ADJUST THE PAINT GUN

CAUTION! While under pressure, never remove the fluid control knob lock nut.

1. The amount of fluid applied to a surface is adjusted by tightening or

loosening the fluid adjustment knob (#18). Tighten the knob clockwise

to reduce fluid flow. Loosen the knob counterclockwise to allow more

fluid to flow into the airstream.

2. The pattern adjustment valve knob (#15) will change the pattern from a

circle to an oval. Turn the pattern adjustment valve set counterclockwise

until seated. The spray pattern will be a solid circle. As the knob is

loosened counterclockwise, the circle will change to an oval that

gradually narrows as the knob is loosened.

3. A pressure regulator gauge is required to control the air flow.

PREPARING TO PAINT

1. Screw the fluid adjustment knob and pressure regulator knob in fully in

prevent air and paint flow.

2. Attach the air hose to the air inlet or tool’s pressure regulator.

3. Set the air compressor to slightly higher than the recommended

operating pressure, but do not exceed the maximum air pressure (see

Specifications). Air pressure may drop when using a long air hose.

4. Fill the paint cup.

5. Adjust the tool’s pressure regulator to the recommended operating

pressure by either tightening or loosening the air adjusting knob.

a. The ideal pressure will vary depending on viscosity and type of

paint. Make adjustments as needed or thin the paint if too thick.

6. Unscrew the fluid adjusting screw to allow the fluid to flow.

7. Spray against the cardboard backdrop to test the paint coverage. Adjust

the pattern adjustment valve to obtain the desired paint pattern. Adjust

the air and paint flow until the desired coverage is reached.

HOW TO PAINT WITH THE SPRAY GUN

1. Ensure that the gun is between 6 and 8 in. from the workpiece. The needed

distance will vary depending on the atomization pressure and work demand.

a. If the spray gun is too close or too far, the finish will not be even.

As a rule of thumb, the distance from the work surface should

equal the longest dimension of the spray pattern coverage.

2. Grip the gun firmly and keep it perpendicular (90°) to the surface of the

workpiece at all times.

3. Move the gun in a straight horizontal line. Press the trigger after

starting the movement and release before ending the movement. This

ensures an even coating (Fig. 1).
