Operation
Trigger Lock
AAC Adjustment
If the spray pattern is not even, the AAC air pressure
may need to be adjusted. For all guns, the AAC air pres-
sure is set at the system. The external mix gun includes
an AAC air pressure adjustment on the gun also, see
AAC reference in F
IG
. 6 on page 17. To increase AAC air
pressure on the external mix gun, turn knob coun-
ter-clockwise. To decrease air pressure, turn knob clock-
wise. For large changes in AAC air pressure, adjust the
pressure at the system.
Trigger Clamp Adjustment
Procedure
1. Engage trigger lock.
2. Loosen four screws (113). Do not remove.
3. While pushing the trigger clamp assembly (111)
against the gun body, use a 9/64 in. hex key to
lightly tighten the four screws.
4. Torque the four screws to 22-24 in-lb (2.5-2.7 N•m)
in the following order: inner two screws first then
outer two screws last.
NOTE: Be careful not to overtighten trigger clamp
assembly as this will cause the material needles to bind
and cause material needles to operate incorrectly.
High-pressure fluid from gun, hose leaks, or ruptured
components will pierce skin. This may look like just a
cut, but it is a serious injury that can result in amputa-
tion.
Get immediate surgical treatment.
• Do not point gun at anyone or at any part of the
body.
• Do not put your hand over the dispense outlet.
• Do not stop or deflect leaks with your hand, body,
glove, or rag.
• Follow Pressure Relief Procedure when you
stop dispensing and before cleaning, checking, or
servicing equipment.
Engage trigger lock whenever you stop spraying to
avoid accidental triggering.
