WARNING

FIRE AND EXPLOSION HAZARD

To reduce the risk of static sparking and splashing when priming or flushing the system, hold a metal part of the gun

firmly to the side of a grounded metal pail before triggering the gun.

7.To prime the hose, lower the pressure to reduce splashing. Hold a metal part of the gun firmly against and aimed into a grounded metal pail. See the preceding WARNING. Hold the gun trigger open and slowly increase the pressure until the pump starts. Keep the gun triggered until all air is forced out of the system and the fluid flows freely from the gun. Release the trigger and engage the gun safety latch.

8.Check all fluid connections for leaks. Relieve pressure before tightening the connections.

9.Engage the gun safety latch.

10.Install the spray tip and tip guard. Install the spray tip. If you are using the RAC IV tip guard, refer to manual 308644 for installation instructions.

11.Adjust the spray pattern

a.Increase the pressure until spray from the gun is completely atomized. To avoid excessive overspray and fogging, and to extend tip and sprayer life, always use the lowest pressure needed to get the desired results.

b.If more coverage is needed, use a larger tip rather than increasing the pressure.

c.Adjust the direction of the spray pattern. See Fig. 9. Engage the gun safety latch. Loosen the retaining nut (A). Position the tip guard for a horizontal or vertical pattern. Hold the tip guard in place and tighten the retaining nut.

NOTE: Spray patterns will change as tips wear. Change the spray tip if adjusting the pressure will not improve the spray pattern.
