General Spraying Techniques

D Select proper fluid set. To determine correct fluid

set see charts on page 10.

D When fluid is first applied, start with fluid nozzle and

air cap adjusted to "normal spray pattern" position.

Then adjust as needed. See Fig. 10 for pattern size

adjustment.

D Keep gun perpendicular to surface and maintain

consistent distance of approximately 6 to 8 inches

(150 to 200 mm) from object being sprayed.

See Fig. 13.

D Always have spray gun in motion before triggering.

Move spray gun across workpiece in straight,

smooth, stroke. Maintaining speed and distance.

Release trigger at end of stroke.

D To obtain even finish, overlap previous strokes

by 50%.

D Apply full, wet coat whenever possible.

Automotive Spraying Techniques

D When blending spots, work from outside in.

D Two 20-foot (6.1 m) hoses are recommended when

applying automotive finish coats. Additional hose

allows air to cool for better flow.

Turbine Filter Maintenance

Turbine systems are lifetime lubricated. The only

maintenance required is filter cleaning and

replacement.

Turbine main filter and pre-filter must be clean at all

times to provide sufficient air flow to cool motor and

atomize fluid. Check turbine pre-filter daily for

cleanliness. Check the main paper filter weekly,

minimum. Clean as necessary.

NOTE: To check filter, turn on turbine and place piece

of paper against pre-filter. If air intake holds paper in

place, filter is okay.
