WARNING
To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 4.
SKIN INJECTION HAZARD
NOTE: Numbers and letters in parentheses in the text
correspond to the reference numbers and letters in the
text and drawings.
WARNING
Be sure your system has a bleed-type
master air valve (pneumatic pumps
only) and a fluid drain valve. These two
accessories 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 or gun.
1. The bleed-type master air valve relieves air
trapped between this valve and the pump after
the air regulator is shut off. Trapped air can
cause the pump to cycle unexpectedly.
2. The fluid drain valve assists in relieving fluid
pressure in the displacement pump, hose,
and gun; triggering the gun to relieve pressure
may not be sufficient.
SKIN INJECTION HAZARD
1. Connect a grounded fluid hose to the gun inlet.
2. With no tip installed, start the pump/sprayer. Flush
it according to the instructions supplied with it.
Prime the system with the fluid you are using.
3. Relieve the pressure.
