WARNING
Two
required components are supplied with your
pump, to help reduce the risk of serious injury
including fluid injection, splashing in the eyes or on
the skin, or injury from moving parts if you are
adjusting or repairing the pump.
The
bleed-type master air valve (B)
relieves air
trapped between this valve and the pump. T
rapped
air can cause the pump to cycle unexpectedly
.
To
bleed air from the pump, the pump air regulator
(F) must be open when you close this valve.
The
fluid drain valve (H)
assists in relieving fluid
pressure in the displacement pump, hose, and gun;
triggering the gun to relieve pressure may not be
sufficient.
Install an air line filter (E) in the main air line, to re
-
move harmful dirt and moisture from the compressed
air supply
. T
o provide automatic lubrication of the air
motor
, install an air line lubricator (P) downstream from
the pump air regulator (F). Install a second master air
valve (D) in the main air line, to isolate the accessories
for servicing.
Mounting the Pump
Mount
the wall bracket 5 ft (1.5 m) above the floor
. Be
sure the wall is strong enough to support the weight of
the pump and accessories, fluid, hoses, and stress
caused during pump operation. See Fig. 2 for a brack
