4.2 VALVE DISASSEMBLY SEQUENCE
4.2.1 VALVE HANDLE REMOVAL
1. Remove both BUTTON HEAD CAP SCREWS (4) from VALVE HANDLE (2) using a 3/16” hex key.
2. Slide CAM and SAFETY PINS (3 and 7) out of handle by gently tapping nozzle against work surface.
3. To remove handle, pull upward while containing the DETENT BALLS (6) and SPRINGS (8) with your thumbs to prevent their loss.
Service to interior valve parts should be done prior to reinstalling handle.
4.2.2 SLIDER AND SEAL REMOVAL
1. With handle and front end removed, pull the SLIDER (17) out from front of valve. It may be necessary to tap the open end of the
VALVE BODY against a rubber or wood block to get the slide valve to come out.
2. Remove and discard QUAD-RINGS-4124 and -4216 (11 and 15), and O-RING-030 (16).
4.3 VALVE ASSEMBLY SEQUENCE
4.3.1 SLIDER AND SEAL INSTALLATION
1. Inspect SLIDER (17) for any raised metal at groove area and replace if necessary.
2. Insert QUAD-RINGS-4124 and -4216 (11 and 15), and O-RING-030 (16) into the appropriate grooves in the valve body.
3. Lubricate O-Rings and slider with silicone grease.
4. Push slider into the valve body narrow end first aligning the groove with the holes for the handle screws.
4.3.2 VALVE HANDLE INSTALLATION
1. Insert DETENT SPRINGS (8) and DETENT BALLS (6) into the handle lugs.
2. While holding balls in place, snap the HANDLE (2) onto valve body with offset holes FORWARD.
3. Carefully align the groove on SLIDER (17) with offset hole in valve discs and offset hole in handle.
4. Start SAFETY PIN (7) into offset hole in handle. Push down into engagement with groove in slider, until head of pin is flush with
handle. Repeat procedure for CAM PIN (3). Be sure to use one CAM PIN and one SAFETY PIN in each handle assembly.
5. Apply Loctite #271 to the threads of both BUTTON HEAD SCREWS (4) and insert through lower handle holes. Thread each into
corresponding center disk hole. Tighten button head screw securely.
6. Cycle handle and check that it snaps firmly and smoothly into all detent positions and that slider moves back and forth. If
performed correctly, the face of the slider will follow the internal contour of the valve body.
4.3.3 VALVE SHUTOFF ADJUSTMENT
Shutoff valve is adjusted by the threads between the valve body and the front portion of the nozzle.
1. While holding the VALVE HANDLE (2) against stops in the OFF position, screw front end into the valve body until firm contact is
made with the valve plug.
2. Open handle up to remove contact.
3. Screw the front end in 1/12-turn further to give the valve shutoff
compression.
4. Close the Valve Handle to help center the Front End and Valve Body.
5. Apply Loctite #242 to SET SCREWS (14) and thread in both set screws until
they bottom out, without applying pressure.
6. In an alternating fashion, continue turning in set screws until tight.
4.3.4 VALVE ADJUSTMENT FOR SEVERE COLD
To help prevent hose line freezing in cold climates, the valve may be adjusted for intentional leakage by installing the front end as
previously described
and backing off 1/12-turn. The valve can be returned to normal adjustment for complete shut off
during warm weather by following the procedure in the previous section.
