The following procedure covers the replacement of

The Optional M-1265 Spray Gun (part no. 236–020
to 236–022, 236–027 and 236–028) have a two

WARNING
PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of a serious injury, follow the
Pressure Relief Procedure on page 13 before
checking or repairing any part of the gun or sys-
tem.
Disassembly
1. Relieve the pressure.
2. Remove the air cap retaining ring (12) and air cap
(19).
3. Trigger the gun while you remove the fluid nozzle
(20) with the gun wrench (35). See Fig. 1.
CAUTION
Trigger the gun whenever you tighten or remove the
nozzle. This keeps the needle seat away from the
nozzle seating surface and prevents the seat from
being scratched.
