Disassembly for Repair or
Cleaning
NOTE: If replacing only the needle and seat, step 4 and

to clean the gun more thoroughly.
1. Relieve pressure.
2. Disconnect the fluid hose (A) and swivel (if used).
Remove the tip guard (9). Unscrew the spring screw
(21) about 1/4 in. (7 mm) to release spring tension.
See FIG.5.
3. Unscrew the valve seat (2a). Remove the
gasket (2b). See FIG.6.
4. Remove one e-clip (26) then push the pin (18) out of
the gun. Remove the screw (13), pivot pin (23), and
trigger (24). See FIG.7.
To reduce the risk of serious injury from fluid injection
or splashing, always follow the Pressure Relief Proce-
dure on page 5 before servicing the gun.
