4.Test the paint viscosity by dipping a stick into the paint, then observ- ing the rate paint drips from the end. Properly thinned paint will drip about 1 per second.

5.Follow paint manufacturer’s recom- mendations. Experiment with scrap material to determine the correct paint viscosity.

6.Always strain the paint when pouring it into the Cup (28). This will prevent lumps or impurities from clogging the Fluid Nozzle (2).

Adjust the Air Pressure

1.Adjust the air pressure by turning the

Knob on the Air Regulator (37). Pull the Knob out to release, turn to ad- just, then press back in to lock. The air pressure setting can be read on the Air Pressure Gauge (38). The rec- ommended pressure is 15 to 45 PSI.

CAUTION! To prevent tool and accessory failure, re- sulting in injury:

Do not exceed the tool’s maximum air pressure rating.

2.Air pressure can be fine adjusted us- ing the Air Adjustment Valve (31). Air pressure too high will cause splatter- ing, too low will cause drizzling.

Adjust the Paint Volume

1.The amount of paint being sprayed can be adjusted with the Fluid Con- trol Knob (12). To adjust, release the

Lock Nut (11) by turning it slightly counterclockwise.

2.Turn the Fluid Control Knob (12) all the way clockwise to turn off paint flow. Using a scrap material,

squeeze the Trigger (36) all the way. With the Trigger squeezed, turn the Fluid Control Knob (12) counterclock- wise to increase paint flow.

3.When the paint pattern is smooth, lock the setting by turning the Lock- nut (11) clockwise.

Adjusting the

Fan Direction and Pattern

1.The fan shaped spray direction of the paint can be adjusted by turning the

Air Cap (1). Loosen the lock ring, turn the Air Cap as needed then retighten the lock ring.

2.When spraying in a horizontal motion, have the Air Cap (1) turned horizontally to have a vertical fan. When spraying up and down, have the Air Cap turned vertically to have a horizontal fan.

3.The spray pattern can be adjusted by turning the Spray Regulator (20). Turning the knob counterclockwise will open and flatten the pattern.

Turning it clockwise will close the pat- tern making it more round.
