IMPORTANT: FOR MAXIMUM EFFICIENCY. THIS
AIR-WRENCH SHOULD BE OPERATED WITH 90 PSI
OF CLEAN, DRY AIR WHILE RUNNING FREE.
CAUTION: Never use higher air pressure to increase
the output of the Air-Wrench. Overloading will
drastically shorten the life of all Internal parts. DO
NOT use hand sockets!! Use Only Impact wrench
WARNING: ALWAYS USE EYE PROTECTION WHEN
OPERATING THIS TOOL.
Before each shift, drain water out of air tank and blow
condensation from air lines. Blow down compressor
more frequently in hot, humid weather. After clearing air
compressor of moisture and lubricating wrench, connect
to a proper size air hose and select a socket which fits
tool shank and nut closely.
Loose, worn or cracked sockets reduce impact power.
Where possible, use deep sockets in place of long,
springy extension bars which absorb impact. Always
use the simplest hook-up possible, as each connection
reduces available power.
To set Air-Wrench to desired power, select a nut or
screw of known tightness of the same size, thread pitch
and thread condition as those on the job. Turn power
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 wrench 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 Air-Wrench is rated at 112" 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 running off with Air-Wrench. If nut does not start
to move in three to five seconds, use a larger size Air-
Wrench. Do not use Air-Wrench beyond rated capacity
as this will drastically reduce tool life.
An air compressor of at least one horsepower with four
CFM delivery at 100 psi, with an air tank of at least 40
gallons capacity is required.
Pipe and fittings between compressor and air hose
should be at least 1/2 nominal size (5/8 l.D.). Be sure
piping is free of dips or sags where moisture can collect.
Air hose should be at least 3/8 I.D. When two or more
lengths of hose are connected together, all except the
short leader hose should be 1/2 I.D.
Couplers may be used. Do not connect couplers directly
to the air inlet. They increase the overall bulk of the tool,
put an unnecessary strain on the tool inlet threads and
deteriorate rapidly due to vibration.
The use of air filters and air line lubricators is
recommended. Clean air strainer frequently to remove
accumulations of foreign matter which restrict air flow.
Never omit strainer from the Air-Wrench.
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
condition may reduce air supply. Grit t 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 oil and
kerosene. The use of worn or cracked sockets may
prevent the wrench from delivering full power to the
work. If outside conditions are in order, disassemble
tool, replace worn or damaged parts, clean, reassemble
