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 filter screen on at least a weekly schedule . The recommended
hookup procedure can be viewed in the above figure .
The air inlet used for connecting air supply, has standard 1/2" NPT .
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet) . Minimum hose diameter should be 1/2" 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 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 . The oil plug is only
for adding multi-purpose grease after repair or maintenance of the
impact mechanism .
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 position 4 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 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" 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 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 .
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 .
