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 flow
conditions.
C. Regularly check hose, hose fittings
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
/
2
to 1 turn out of
the cut. Engage the Auto-Feed and
restart the Power Operator.

1. BEFORE ATTACHING THE H-614 OPERATOR TO THE DRILLING MACHINE
A. Check the Operating Manual for the
specific Drilling Machine that will be
used for any special instructions for
installing a power operator.
NOTE: If attaching the H-614 Air
Power Operator to an older model
C1-36 Drilling Machine, the old style
Top Bearing (part number 502707)
will have to be replaced with the
newer style (part number 580815),
which includes the attachment arm
for the power operator – contact
your authorized Mueller Distributor.
B. Rotate the Input Shaft on the Drilling
Machine to align with the Coupling
on the Power Operator, remove the
Pivot Pin from the base of the Power
Operator and mount the unit on the
Drilling Machine.
C. Insert Pivot Pin to secure the Power
Operator to the Drilling Machine and
tighten the Thumb Screw.
D. Position and tighten the Hold Down
Wing Nut provided on the Drilling
Machine to complete the installation.
3. INSTALL AIR POWER OPERATOR ONTO THE MACHINE
A. Reposition the Handle/Trigger
mechanism, if necessary, by removing
two (2) hex socket cap screws. Rotate
the Handle/Trigger in 90º increments
to the desired position and secure with
the two screws previously removed.
B. Remove the Air Inlet Bushing from
the Handle/Trigger mechanism and
clean the Filter Screen as required.
IMPORTANT! DO NOT lose the
O-ring Seal and Filter Screen. Do
not operate the Air Motor unless
the screen is in place.
Reinstall the
Screen and Air Inlet Bushing.
C. Attach the In-line Lubricator (supplied).
Add air motor lubricating oil to the
Lubricator. Use Mobil DTE Light or
equivalent.
D. After each eight (8) hours of use,
inject one to two “pumps” of gear
lubricant through the grease fitting.
Use Mobilux EP-2 or equivalent.
