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
tightness - note

WARRANTY POLICY: This NAPA
PROFESSIONAL AIR TOOL, 6-1071,
is warranted against defects in
material and workmanship for a
period of one (1) year from the
date of the original purchase.
We will replace any defective
part or unit which proves to
be defective in material or
workmanship during this one
year period. In the unlikely event
a replacement unit is req­uired

for future use. When tightening
nuts not req­uiring critical torq­ue
values, run nut up flush and then
tighten an additional one-q­uarter
to one-half 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 /" 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.

with impact wrench. If nut does
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 forward/reverse lever is used
to change the rotation of the tool.
When the lever is moved to the
right, the tool is in a forward or
right hand rotation. When the
lever is moved to the left, the
rotation is reverse or left 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.
