Operating Instructions and Parts Manual

Preparation (continued)

6.Attach the air hose quick-connect fitting to the gun.

NOTICE	The quick-connect
	fitting outer sleeve is

spring loaded and must be pulled back to attach or remove it from the gun (See Figure 10).

Operation

Always practice first. Make the gun adjustments on a test surface such as

cardboard before spraying the project.

1.Keep the gun 4" - 9" from, and

parallel to the surface of the object being sprayed. (See Figure 11). If the material delivery is adjusted for a small narrow pattern, it may be necessary to move as close as 2" from the work surface.

Reducing the air flow also reduces overspray.

NOTICE	The turbine air
	hose can be used to

blow-dry those areas that are too heavily coated, or slow in drying.

The air from the turbine is warm as a result of normal operation. This can affect the finish quality on hot dry days due to premature drying of some coatings such as lacquer. Retarding agents can be added to the material to resolve this condition. Consult the material supplier for the proper retard- ing agent, and mixing procedures.

Maintenance

CLEANING

!WARNING Make sure the room is well ventilated

when using solvents. Dispose of all materials properly, in accordance with all local regulations.

1.Remove the material control knob, spring, and needle. (Pull the trigger to help remove the needle). NOTICE: Removing the needle prior to removing the nozzle will prevent needle damage.

2.Using the supplied wrench, unscrew and remove the retainer ring, nozzle, and airflow ring (See Figure 15).

Figure 11 - Painting Strokes

2.Move the gun in a smooth even stroke. Begin the stroke before pulling the trigger and continue the stroke after releasing the trigger.

3.For best results overlap each stroke by 25 to 50%.

4.To adjust the spray pattern “type”, turn the air cap to the desired pattern position (See Figure 12).
