Installation
10 309292L
Connect the Fluid Line
1. Before connecting the fluid line (N), blow it out with
air and flush it with solvent. Use solvent which is
compatible with the fluid to be sprayed.
2. Install a fluid regulator (M) on the fluid line to control
fluid pressure to the gun.
3. Install a fluid filter (K) and drain valve (U) at the
pump outlet.
4. Connect the fluid line to the 3/8 npsm gun fluid inlet
(W).
5. Before running any paint through the spray gun,
flush it out with a compatible solvent.
Filter the Fluid
Install a fluid filter (K) to remove particles and sediment
which could clog the spray nozzle.
Select a Fluid Nozzle and Air
Cap
The gun is supplied with Part No. 197266 Nozzle and
197477 Air Cap. If you require a different size, refer to
Table 1 and Table 2 , and instruction manual 309419, or
consult with your Graco distributor. See Air Cap/Nozzle
Replacement on page 26.
* Glass-reinforced acetal construction.
WARNING
Pressurized Equipment Hazard
The fluid drain valve (U) is required in your
system to assist in relieving fluid pressure in
the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may
not be sufficient. Install a drain valve close
to the pump's fluid outlet. The drain valve
reduces the risk of serious injury, including
splashing in the eyes or on the skin.
WARNING
Pressurized Equipment Hazard
To reduce the risk of an injury, follow the
Pressure Relief Procedure on page 24
before removing or installing a fluid nozzle
and/or air cap.
