Operation
Priming the System
See
Fig. 1
1.
Close the gun air regulator (F).
2.
If your system has a fluid pressure regulator (G),
close it.
3.
Open the bleed-type master air valve (K).
4.
Slowly set the pump air regulator (E) pressure to
20 to 30 psi (140 to 210 kPa, 1.4 to 2.1 bar). The
pump cycles quickly
, then it slows down when it is
primed. Set the pump air pressure to 40 psi (280
kPa, 2.8 bar).
5.
Slowly open the gun air regulator (F), and pull the
gun trigger just enough to open
only the air valve
in the gun. With the gun air triggered, set the gun
air pressure to 60 psi (413 kPa, 4 bar).
6.
Hold the gun against and aimed into a grounded
metal waste pail, and fully trigger the gun. If your
system has a fluid pressure regulator (G), slowly
open it.
The gun emits air until the fluid arrives. When fluid
flows freely
, release the gun trigger
.
