1. Connect a fluid hose (Z) to the gun inlet. Use swivel
17G980 or 17G981 if desired (order separately).

the pump. Flush the pump according to the
instructions supplied with it. Use the lowest
pressure possible.

6. Start the pump. Trigger the gun onto test paper.
Adjust the fluid pressure until the spray is
completely atomized.
NOTE: Use the lowest pressure necessary to get the
desired results. Higher pressure may not improve the
spray pattern and will cause premature tip and pump
wear.
7. If adjusting the pressure does not give a good spray
pattern, relieve pressure and try another tip size.
8. When spraying, use a full-open, full-close trigger
action to get uniform coverage of applied media.
Hold the gun about 14 in. (350 mm) from and at
right angles to the work surface. Do not swing the
gun in an arc. Practice to find the best length and
speed of stroke.
Pulling hoses with the gun can cause the fluid housing
to loosen. This could result in the gun not shutting off
when the trigger is released.
•
Do not pull hose with gun. Always pull hose with a
separate hand.
•
Periodically verify that the set screw in the fluid
housing remains tight.
Adjust the Spray Pattern
1. Follow the Pressure Relief Procedure, page 7.
2. Loosen the tip guard retaining nut (RN).
3. Rotate the tip guard (H) as necessary to achieve a
vertical or horizontal spray pattern. Tighten the nut
(RN).
