NOTE:
To ensure the maximum pump performance, be
sure that all the accessories used are properly sized to
meet your system requirements. Use only genuine
Graco parts and accessories.
In the air line, install an air filter to remove harmful dirt
and moisture from the compressed air supply. Install an
air line lubricator downstream from the air filter, the sup-
plied air regulator, and the bleed-type master air valve.
The lubricator provides automatic lubrication to the air
motor.
The supplied bleed-type master air valve is required in
your system to relieve the air trapped between the
valve and the pump after the pump is shut off. Trapped
air can cause the pump to cycle unexpectedly, which
can result in serious injury.
Connect a 1/2" minimum ID grounded air supply hose to
the 1/2 npt(f) port of the air regulator. Open the bleed-
type master air valve and set the air regulator to the
desired pressure, using the pressure gauge.

• To maintain grounding continuity when flushing or
relieving pressure:
gun firmly to the side of a grounded metal pail, then
trigger the gun.
• All solvent pails used when flushing:
