Install the Gun on the
Manifold
1. Make sure the gasket (112) and spring (105) are in
place on the manifold. See F
IG . 22.. Inspect the
parts for damage and replace them as needed.
2. Secure the gun to the manifold by tightening the
three screws (106).
3. Secure the gun to the mounting bracket (102) by
tightening the bottom screw (31).
CAUTION
The piston return spring (105) is compressed
between the manifold and the gun body when they
are assembled. To avoid sudden movement of the
gun, loosen the bottom gun screw (31) before loosen-
ing the three manifold screws (106). This allows the
gun to move forward gradually as the manifold
screws are loosened. Hold the gun firmly in hand
while loosening the manifold screws.
