Clean air of correct air pressure is recommended for the power supply
for this tool. A maximum of 90 PSI at the tool is recommended for most
air tools of this class. Check specifications section for recommended
pressure. (Depending on length of air hose and other circumstances, air
pressure at compressor may need to be increased to 100 PSI to ensure
90 PSI at the tool.)
Water in the air hose and compressor tank contributes to reduced per
-
formance and damage of the air tool. Drain the air tank and filters before
each use and as necessary to keep the air supply dry.
Hose length over 25’ causes loss in line pressure. Increase hose I.D. or
increase compressor pressure to compensate for the pressure loss. Use
an in-line pressure regulator with gauge if air inlet pressure is critical.
OPERATION
1. To set the tool to desired torque, select a nut or screw of known tight
-
ness of the same size, thread pitch and thread condition as those on
the job.
2. 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.
3. 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).
4. For additional power needed on disassembly work, turn regulator to
its fully open position. This impact wrench is rated at 1 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
fasteners as they absorb much of the impact power. When possible,
clamp or wedge the bolt to prevent spring back.
5. Soak rusted nuts in penetrating oil and break rust seal before remov-
ing 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.
