Adjust AAC
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. 7 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.
Internal Mix Flush
NOTE: The recommended solvent line pressure is
80-100 psi (550-700 kPa, 5.5-7.0 bar).
After spraying, open the solvent knob (BC) to allow sol-
vent to flow through the gun. See F
IG. 7 on page 17.
While flushing, hold a metal part of the gun firmly to a
grounded metal pail.
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.
