Barrel Removal
1. Prepare the gun for service as instructed on page
28.
2. 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) Loctiter to setscrews
before re-installing them.
3. Loosen the three cap screws (5), using the 4 mm
driver (55), supplied.
4. 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, gently
move the gun barrel from side to side to free it from
the gun handle.
