WARNING
COMPONENT RUPTURE HAZARD
Do not exceed the 100 psi (0.7 MPa,
7 bar) maximum fluid and air pres-
sure of this gun. Higher pressures can cause parts
to rupture and result in serious injury.
Follow these steps to establish the correct fluid flow
and air flow:
A. Turn the fluid adjustment knob (8) counterclock-
wise until no restriction of the trigger movement is
felt, then turn the knob another half turn. When the
knob is turned far enough, the trigger should be
able to touch the gun handle when the gun is trig-
gered.
