4. OPERATING INSTRUCTIONS
WARNING: Use only the hand to
hold down the Throttle of the Power
Operator. Using other means to hold
down the Throttle could prevent
the Power Operator from being
stopped quickly if necessary, which
may create a dangerous situation
resulting in serious bodily injury.
CAUTION: The H-614 unit operates
the Shell Cutter and feed faster than
previous models of air power
operators. This must be considered
when making a cut. Pneumatically
driven power tools are not generally
insulated against coming in contact
with sources of electrical current. Take
necessary precautions if sources of
electrical current are nearby.
A. Use recommended lubricants only.
B. Maintain 90 psig (6.2 bar/621 kPa)
air pressure at the inlet of the power
operator, using at least a 3/4” supply
hose. DO NOT EXCEED 100 psig
(6.9 bar/689 kPa) under any ow
conditions.
C. Regularly check hose, hose ttings
and clamps for tightness and service-
ability – avoid risk of whipping hose.
D. Check to assure the exhaust air will
be directed toward a safe direction
to avoid blowing dust or air from the
machine onto the operator or other
persons in the area.
E. In the event of a stall, release the
Throttle immediately. Pause for a
moment, then restart the Power
Operator. If the unit stalls upon
restart, disengage the Drilling
Machine’s Auto-Feed, manually back
the Shell Cutter 1/2to 1 turn out of
the cut. Engage the Auto-Feed and
restart the Power Operator.
