WARNING
To reduce the risk of fluid injection, always grasp
the nozzle housing (B) from the threaded end, not
from the front, when adjusting the nozzle.
If you are not using a Hi–Flow nozzle, remove the cap
(A) from the tube. See Fig 5.
When dispensing lightweight fluids, such as automatic
transmission fluid, increase the free play of the dispense valve trigger. This reduces the flow and reduces
splashing of the fluid. To adjust the trigger free play,
loosen the adjusting screw locknut (C). Back the screw
(D) out until the desired flow is achieved, then tighten
the locknut securely. See Fig 6.
To lock the control valve in the open position, engage
the trigger latching pin in the latch (E). See Fig 6. To
release the latch, squeeze and release the trigger.
To dispense from the Hi-Flow nozzle (B), turn the
knurled sleeve clockwise until it is open. Trigger the
valve. See Fig 5.
When the dispense cycle is completed, release the
trigger and close the nozzle by screwing the knurled
sleeve fully counterclockwise. See Fig 5.
For electronic metered valves, press the RESET key
pad on the meter to clear it before the next dispense
cycle. See Fig 1.
Trigger the dispense valve. Lubricant begins to flow
with the slightest movement of the trigger, and continues to flow until the trigger is released.

Clean the Strainer Frequently
Relieve pressure. Remove the swivel (19) and unscrew the strainer (19a). Clean the filter in mineral spirits. Reassemble, and torque the swivel to 19–21 ft-lb
(26–28 N.m).
Check Internal Valve Parts
Relieve pressure. Disconnect the valve from the hose.
Remove the valve plug (22). Several other parts will
come out with the plug. Clean the valve cavity and
seat (18). Inspect the seat for nicks. If the seat is damaged, send the valve to a Graco–authorized service
center for repair. Reassemble the valve.
Replace Push Rod or Packing
Relieve pressure. Disconnect the valve from the hose.
Push out the pin (2) of the trigger latch. Swing the trigger out of the way. Remove the guide (10), gasket (4)
and push rod (20). Use a dull instrument to remove the
packing (12). Install a new gasket and reassemble the
valve.
Adjust the Valve
Loosen the locknut (8). Turn the adjusting screw (9) in
or out as needed. To stop the fluid flow, all of the pressure of the screw (9) against the push rod (20) must
be released.
When the valve handle is properly adjusted, there is a
small amount of free play. After adjusting the valve,
hold the adjusting screw in place and securely tighten
the locknut.
