SX231P-2: Parts Breakdown & Operating Manual 3 08/20/13
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 1/2 ounce.
Operation
This tool includes an adjustable power management system that allows the operator to adjust power in the clockwise direction (forward) and counter
clockwise direction (reverse).
To set tool up with full power output in forward direction and full power in the reverse direction; rotate the power dial until the notch on the dial aligns
with the number 5 setting on each side of the tool.
To set tool up with reduced power output in forward direction and full power in the reverse direction; push the reversing valve out in the clockwise
direction (forward) and adjust the dial to the desired number in the forward direction. You will see that when the reversing valve is switched back to
counter clockwise, the tool will have full power output.
To set tool up with full power output in forward direction and reduced power in the reverse direction; push the reversing valve out in the counter clock-
wise direction (reverse) and adjust the dial to the desired number in the reverse direction. You will see that when the reversing valve is switched back
to clockwise, the tool will have full power output.
The Power management system is only for reference and does not act as a torque control tool. This tool includes a plunger style variable speed trigger
that further allows the operator to control output power in the clockwise direction.
This impact wrench is rated at 1/2" SAE 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. The reversing valve is used to
change the rotation of the tool. When the valve is out, the tool is in a forward or right hand rotation. When the valve is pushed in, the rotation 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.
