Air Supply...
Tools of this class operate on a wide range of air pres s ures. It is
recommended that air pres s ure of these tools mea s ures 90 PSI at the
tool while running free. Higher pres s ure (over 90 psig; 6.2 bar) raises
per f or m ance beyond the rated capacity of the tool which will short e n
tool life be c ause 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 filter screen on at least a weekly schedule. The rec o m m end e d
hookup pro c e d ure can be viewed in figure 1.
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 fittings should have the same inside dimensions and be tightly
secured.
Lubrication...
Lubricate the air motor daily with quality air tool oil. If no air line oiler
is used, run 1/2 ounce of air tool oil through the tool by squirting oil
into the tool's air inlet or into the nearest connection to the air inlet,
reconnecting air supply, and then running tool. Do not use more than
1/2 ounce of oil, as overfilling will reduce the performance of the
tool.
Troubleshooting...
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connections
of improper size or poor conditions may reduce air supply. Grit or
gum deposits in the tool may cut power and may be corrected by
cleaning the air strainer and flushing out the tool with gum solvent
oil or an equal mixture of SAE #10 and kerosene. If outside conditions
are in order, disconnect tool from hose and take tool to your nearest
authorized service center.

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 ap p rox i m ate
tightness of a known fastener.
To set the tool to de s ired torque, select a nut or screw of known
tight n ess of the same size, thread pitch and thread con d i t ion as
those on the job. Turn air reg u l a t or to low position, apply wrench
to nut and gradually increase pow e r (turn regulator to admit more
air) until nut moves slightly in the di r ec t ion it was originally set. The
tool is now set to du p li c ate that tight n ess - note reg u l a t or setting
for future use. When tight e n i ng nuts not requiring critical torque
values, run nut up flush and then tighten an additional one-quarter
to one-half turn (slight ad d i t ion a l turning is necessary if gaskets
are being clamped). For additional power needed on dis a s s em b ly
work, turn regulator to its fully open position. This im p act wrench
is rated at 1/2" 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 fas t en e rs, as they absorb much of the
impact power. When possible, clamp or wedge the bolt to prevent
springback.
Soak rusted nuts in pen e t rat i ng oil and break rust seal before
removing with im p act wrench. If nut does not start to move in three
to five sec o nds, use a larger size impact wrench. Do not use impact
wrench be y ond rated ca p ac i t y, as this will dras t i c al l y 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 ro t a t ion 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.
