Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1.Close the supply pump’s bleed-type master air valve (required in pneumatic systems).

2.Open the dispensing valve until pressure is fully relieved.

3.Open the fluid drain valve at the pump fluid outlet. Leave the drain valve open until you are ready to use the system again.

NOTE: If you suspect the dispensing valve, extension, or grease fitting coupler is clogged, or the pressure has not been fully relieved after following the previous steps, using a rag VERY SLOWLY loosen the coupler or hose end coupling and allow pressure to be relieved gradu- ally, then loosen the part completely then clear the clog.

Adjustment

The dispense valve provides positive control of high pressure lubricants. When supplied with air the pump will start when the valve is triggered and still stall against pressure when the trigger is released.

1.Relieve the pressure, see Pressure Relief Proce- dure.

2.To adjust the clearance, loosen the top nut (5, Fig 1) and turn the bottom nut (5) in or out as needed. To increase grease flow turn bottom nut in. To reduce grease flow turn bottom nut out. Hold the bottom nut in place and securely tight the top nut.
