Operation
Starting and Adjusting the Pump
Fill the wet–cup (25) half full with Graco Throat Seal
Liquid (TSL). With the drain valve and bleeder valve
closed, and the gun/valve safety disengaged, trigger
the gun/valve and slowly open the air supply valve until
the pump starts. If fluid does not flow from triggered
gun/valve, open the bleeder valve (12) slightly. See
Fig. 3. When fluid appears, close bleeder valve.
WARNING
Keep your hand and fingers away from the priming
piston and fluid intake valve (R) to reduce the risk
of serious bodily injury, including amputation.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun/valve is triggered and released.
In a circulating system, it will run continuously and
speed up or slow down as supply demands until air
supply is shut off.
Use an adequately sized air regulator (F) to control
pump speed and fluid pressure. See the
Installation
drawing on page 7. Always use the lowest pressure
necessary to give you the results you want.
Never exceed the maximum air pressure to the pump
(see
Technical Data
on page 17).
