OPERATION
These tools are lever operated torque control
tools. The air motor starts when the operating
lever is depressed. (Hold the lever ully depressed
in order to achieve uni orm motor per ormance.)
The tool stops automatically a ter the clutch has
released its preset torque into the astener. To
restart the tool, release the lever and depress
again or the next astener. (It is normal or the
tool to bleed a small amount o air thru the
exhaust a ter the tool has stopped and the lever
is still depressed.)
Lever operated tools have a speed control lo-
cated under the lever. Rotate the valve in either
direction to control the tool speed. (Do not reduce
tool speed so low that the output torque is lower
than the clutch setting torque. This will result in
the tool stalling be ore the clutch releases.)
The clutch design allows or consistent torque
control in the orward (right hand) direction only.
The clutch will operate in the reverse (le t hand)
direction but at a much higher release torque with
more torque scatter.
LUBRICATION
The lubrication received during assembly is sat-
is actory or 500,000 cycles. When servicing the
tool, use 1/4 oz. o Sioux #1232 grease in the
gearing and clutch and 1/8 oz. in the angle head.
CLUTCH ADJUSTMENT
Tools are shipped with the clutch adjusted to high
torque setting so that the locking screw is on
center position to the circular H mark on the
clutch case. High and low torque settings or the
clutch are set by adjusting the clutch externally or
internally (see below) to center the locking screw
#07096 in the marked circles with H and L
designation.
External AdjustmentUncouple air hose rom
tool to prevent accidental start up. Remove two
#07096 screws with 1/8" allen wrench. One screw
is on outside o clutch case which unlocks the
adjustment nut on the inside o the clutch case.
The other screw is in the inlet end o the tool which
retains the #65138 pin in storage. Remove pin
rom storage hole and insert pin in adjustment nut
hole. Turn the output spindle with #65204 wrench
until the pin drops thru the driving slot o the
spindle. The pin must drop ar enough to clear the
internal threads o the clutch case. Turn the
spindle clockwise to increase torque (adjustment
nut has right hand threads). Turn the spindle until
the screw hole in the adjustment nut is centered
on circular H or L mark. Do not turn adjustment
nut by running the motor. The pin will drop reely
rom hole when the tool is tapped with hand.
Install locking screw and test tool. Return pin to
storage hole and replace screw to retain the pin.
Internal AdjustmentUncouple air hose rom
tool to prevent accidental start up. Remove #07096
screw with 1/8" allen wrench rom outside o
clutch case to unlock adjustment nut. Also, re-
move angle head assembly. Pull drive spindle
rom tool. The adjusting nut can be turned with a
1/2" square drive socket extension. The adjust-
ment nut has right hand threads. Turn the adjust-
ment nut until the screw hole is centered on
circular H or L mark and install locking screw.
