Graco 242058 Manual De Usuario

Follow the Pressure Relief Procedure whenever 
you see this symbol.

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.

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.

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.
