USING THE POWER MANAGEMENT SYSTEM

Air wrenches are not torque control devices. Fasteners with specific torque requirements must be checked with suitable torque measuring devices after installation with an air wrench.

MODEL IR-C2131 POWER

MANAGEMENT SYSTEM

POWER SETTING INDICATORS

MAXIMUMMINIMUM

POWER

MANAGEMENT

DIAL

Model IR-C2131 Impact Wrench incorporates a Power Management System that allows the operator to select four power output sett ings. These settings range from minimum power output through maximum power output in the forward direction only. The Air Wrench will always operate at maximum power output in the reverse direction, no ma tter what power output level is selected.

The four power setting indicators of increasing size on the rear of the housing indicate increasing power output levels, are for reference only and DO NOT denote a specific power output. The smallest power setting indicator designates minimum power output, the two middle power setting indicators denote medium power outputs and the largest power setting indicator denotes maximum power output. The power output can be further reduced in forward or reverse by using the variable throttle. Air supply systems which do not deliver adequate air pressure can affect power output at all settings.

MAINTENANCE SECTION

General Instructions

1. Do not disassemble the tool any further than necessary to re place or repa ir damaged parts.

2. Whenever grasping a tool or part in a vise, always use leather--covered vise jaws to protect the surface of the part and he lp prevent distortion. Thi s is particularly true of threaded members and housings.

Always use leather--covered vise jaws when clamping the handle in a vise. Leather will conform to the shape of the handle and allow the tool to be held securely. To prevent damage to the exhaust diffuser, never clamp only the bottom of the handle.

3. Do not remove any part which is a press fit in or on a subassembly unless the removal of that part is necessary for repairs or replacement.

4. Do not disassemble the tool unless you have a complete set of new ga ske ts and O--rings for replacement.

Disassembly of the Impact Wrench

1. Clamp the handle of the impact wrench in a vise with leather--covered jaws with the square driver positioned horizontally.

Note the twin hammers within the Hammer Frame. These are identical, but must be placed in the Hammer Frame in a certain relationship. Using a felt--tipped pen, mark he top “T↑ ” hammer and

the bottom hammer “B↑ ”withthearrows pointing upward. Mark both Hammers on the same end.

2. With the mechanism sitting upright on the workbench, slowly rotate the Anvil in a clockwise direction until it comes up solid.

If you continue to rotate the Anvil, it will cam the Hammers out of engagement. Don’t do this; merely rotate the Anvil until it comes up solid.

3. Hold the Hammer Frame firmly and without disturbing the hammers, gently lift the Anvil while simultaneously rotating it clockwise about 1/8 of a turn, from the Hammer Frame.

4. With the Anvil removed, lift out the two Hammer Pins.
