Instruction Manual
This product is designed to tighten or loosen threaded
fasteners. No other use is permitted.
Air Supply Requirements
Tool is designed to operate at 90 psi (6.2 bar) at free speed
measured at the tool, of clean, dry air. Operating this tool at
higher pressures will drastically reduce the tool life and could
cause injury.
The air inlet thread on this tool is a standard 1/4" NPT.
Line pressure should be increased for any unusually long
air hose run (over 25 feet). Minimum hose diameter should
be 3/8" I.D. and all fittings should have the same inside
diameter. See diagram below for proper air supply setup.
Lubrication
Lubricate the tool each day after use with quality SAE #10
air motor oil. Add the oil to the air inlet or into the hose at the
nearest connection to the air supply, then run the tool until
all excess oil is expelled from the exhaust. Total oil quantity
needed for this procedure is approximately 1 ounce.
Operation
This tool is an impacting tool and not a torque meter.
When specific torque is required, it must be checked with
a torque meter after fitting the fastener with the Impact.
If a nut does not move within five seconds, use a larger size
Impact. Do not use Impact Wrench beyond rated capacity, as
this can drastically reduce the tool life.
