Operation
Note
: The following instructions are for guns used with
Graco FinishPro Sprayers. See the sprayer instruction
manual 313316. If you are using a different sprayer, see
your equipment instruction manual.
Setup
1. Prime sprayer. See manual 313316.
2. Slide air on/off valve on (up).
3. Turn air adjustment valve off at
gun.
4. Increase fluid pressure to
eliminate tails.
5. Decrease fluid pressure until
just before tails start to
appear.
6. Increase air pressure with air
adjustment valve to eliminate
tails.
7. Slide air on/off valve off
(down) when finished spraying
to save proper air pressure
setting.
Spray
1. Unlock trigger lock.
2. Be sure the arrow shaped tip (B) faces forward
(spray) (257096).
3. Hold gun perpendicular and approximately 12 in.
(304 mm) from surface. Move gun first, then pull gun
trigger (D) to spray a test pattern.
4. Do not spray in an arc. This causes an uneven fluid
coat. Spray in a path parallel to the surface, with a
50% overlap, to obtain an even fluid coat.
NOTICE
If air cap is not fully installed on gun, fluid pressure
can force paint into air line and damage sprayer.
