Operating Instructions • Warning Information • Parts Breakdown
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
 • leadfromlead-basedpaints,
 • crystallinesilicafrombricksandcement
and other masonry products, and
 • arsenicandchromiumfrom
  chemically-treatedlumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.

Operating Instructions • Warning Information • Parts Breakdown
AIR SUPPLY
Tools of this class operate on a wide range of air pressures.
It is recommended that air pressure of these tools measures
90 PSI at the tool while running free. Higher pressure (over
90 psig; 6.2 bar) raises performance beyond the rated
capacity of the tool which will shorten tool life because of
fasterwearandcouldcauseinjury.
Always use clean, dry air. Dust, corrosive fumes and/or
water in the air line will cause damage to the tool. Drain
theairtankdaily.Cleantheairinletlterscreenonatleast
a weekly schedule. The recommended hookup procedure
canbeviewedintheabovegure.
The air inlet used for connecting air supply, has standard
1/4" NPT. Line pressure should be increased to compensate
for unusually long air hoses (over 25 feet). Minimum hose
diametershouldbe3/8"I.D.andttingsshouldhavethe
same inside dimensions and be tightly secured.
LUBRICATION
Lubricate the tool daily with quality air tool oil. If no air
line oiler is used, run a half ounce of oil through the tool.
The oil can be squirted into the tool air inlet or into the
hose at the nearest connection to the air supply, then run
thetool.Overllingwillcauseareductioninthepowerof
the tool. A rust inhibitive oil is acceptable for air tools.
OPERATION
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 regulator setting 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 1/2" SAE
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 impact wrench. If nut does not start
tomoveinthreetovesecondsusealargersizeimpact
wrench. Do not use impact wrench beyond rated capacity
as this will drastically reduce tool life.
The reversing valve is used to change the rotation of the
tool. When the valve is out, the tool is in a forward or right
hand rotation. When the valve is pushed in, 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.
