Remove the Gun from the Manifold and
Mounting Bracket
1. Remove the retaining nut and air cap assembly (1,
12, 13, 15) and the gun shroud (2). See Fig. 27 .
You may have to turn the air cap with the tip guard
to remove the air cap from the gun.
2. Disconnect the fluid hose from the fluid inlet fitting
(3)– marked P1 on the manifold . Use an open end
wrench to hold the fluid fitting hex and prevent it
from turning.
3. Loosen the bottom gun screw (21) until the gun (B)
sits loosely in the mounting bracket slot (A).

CAUTION
The piston return spring (105) is compressed
between the manifold (101) and gun body when
they are assembled. To avoid sudden movement of
the gun, always loosen the bottom gun screw (21)
before loosening the three manifold bolts (106).
This relieves some of the spring force and allows
the gun to move foreward gradually as the manifold
bolts are loosened. Hold the gun firmly in hand
while loosening the manifold bolts.
4. Holding the gun (B) firmly in hand, loosen the three
bolts (106) from the back of the manifold (101)
with the ball end wrench (77), supplied.
5. Remove the gun (B) from the manifold (101) and
bracket (102).
