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.
