Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Shift the High/Low pressure lever back and forth
two times. Leave the lever in the “Low” position
as shown in Fig. 1.

2. Use a T8 Torx screwdriver to remove two
screws (309). Remove the valve plate (305), cup
assembly (312-314), spring (311), and detent
assembly (303).
3. Pull the cup (313) off of the base (312). Remove
the o-ring (314) from the cup.
4. Remove the retaining ring (310) from each end
of the air valve. Use the piston (302) to push

Orient the end of the base that has a magnet
toward the end of the cup that has the larger
cutout. Engage the opposite end of the parts.
Leave the end with the magnet free. Tilt the base

excessively worn, the fasteners may loosen during
operation. Replace screws with new ones or apply
