Barrel Removal - Graco PRO AA4500 Instructions Manual

Barrel Removal

1. Disconnect the bottom fluid tube nut (C). See
Fig. 12.
NOTE: 2-finger trigger guns only
It should not be necessary to remove the fluid fitting
(10) from the bracket. If you must remove it, remove
the two setscrews in the bracket that hold it in place.
Apply a low strength (purple) Loctite to setscrews be-
fore re-installing them.
2. Loosen the three cap screws (5), using the 4 mm
driver (55), supplied.
3. Hold the gun handle (7) with one hand and pull the
barrel (3) straight away from the handle to remove
it. See Fig. 13.
CAUTION
To avoid damaging the power supply (18), always
pull the gun barrel straight away. If necessary, gen-
tly move the gun barrel from side to side to free it
from the gun handle.
