Trigger Adjustment
When the trigger is pulled, it moves the trigger clamp
assembly resulting in fluid flow from each component.
The actuator pins are factory set. If the trigger, trigger
clamp assembly, or pins are removed then the trigger
may need to be adjusted.
1. Perform Pressure Relief Procedure , page 22.
2. Engage trigger lock.
3. Use 5/64 in. Remove adjuster screws (114).
4. Apply medium strength thread sealant to threads of
screws.
5. Install adjuster screws (114) into trigger clamp
assembly (111).
6. Squeeze trigger so that it touches the trigger lock. If
trigger cannot touch trigger lock, back out adjuster
screws until trigger touches the trigger lock.
7. Adjust each screw until the actuator pin just begins
to touch the trigger. This can be verified by the trig-
ger just beginning to lift off of the trigger lock.
8. Back each screw out 1/2 turn.
9. Disengage trigger lock.
10. While watching the trigger clamp assembly, trigger
the gun to verify both sides of the trigger clamp
assembly pull away from the gun body at the same
time.
11. Hold the trigger fully engaged and measure the
space between the trigger clamp and the gun body
on both sides. The gaps should be at least 0.065 in.
(1.65 mm) in the open position. Adjust screws as
necessary. See F
IG
. 10.
Internal Mix Flush
After spraying, open the solvent knob (BC) to allow sol-
vent to flow through the gun. See F
IG
. 6 on page 17.
While flushing, hold a metal part of the gun firmly to a
grounded metal pail.
