OPERATION
The air regulator knob can be used
as an air throttle, if there are no
other means of regulating air. Turn
the air regulator knob all the way
to highest position for max­imum
power.
The air regulator can be used to
adjust torq­ue to the approx­imate
tightness of a known fastener.
To set the tool to desired torq­ue,
select a nut or screw of known
tightness of the same size, thread
pitch and thread condition as those
on the job. Turn air regulator to
low position, apply wrench to
nut and gradually
increase power
(turn regulator to
admit more air)
until nut moves
slightly in the
direction it was
originally set. The
tool is now set to
duplicate that tight­
ness ­ note
regulator setting
for future use.

When tightening nuts not
req­uiring critical torq­ue values, run
nut up flush and then tighten an
additional one­q­uarter to
one­half turn (slight additional
turning is necessary if gaskets are
being clamped). For additional
power needed on disassembly
work, turn regulator to its fully
open position. This impact wrench
is rated at 3/8" USS bolt size.
Rating must be down graded for
spring U bolts, tie bolts, long cap
screws, double depth nuts, badly
rusted conditions and spring
fasteners, as they absorb much of
the impact power. When possible,
clamp or
wedge the
bolt to prevent
springback.
Soak rusted
nuts in
penetrating
oil and break
rust seal before
removing with
Forward/
impact wrench.

not start to move in three to five
seconds, use a larger size impact
wrench. Do not use impact wrench
beyond rated capacity, as this will
drastically reduce tool life.
The Reverse Valve (#3) is used
to change the rotation of the tool.
When the valve is turned fully to
the left, the tool is in a reverse, or
left hand, rotation. When the valve
is moved to any position towards
the right, the rotation is forward,
or right hand.
NOTE: Actual torque on a fastener
is directly related to joint hardness,
tool speed, condition of socket
and the time the tool is allowed to
impact.
Use the simplest possible tool-to-
socket hook up. Every connection
absorbs energy and reduces power.
