INSTRUCTIONS FOR

MODELS 231 AND 231-2 HEAVY-DUTY

AUTOMOTIVE IMPACT WRENCHES

Model 231 and 231-2 Impact Wrenches are designed for use in general automotive repair, body shops, front end service and light truck and farm equipment applications.

Ingersoll-Rand is not responsible for customer modification of tools for applications on which Ingersoll-Rand was not consulted.

IMPORTANT SAFETY INFORMATION ENCLOSED. READ THIS MANUAL BEFORE OPERATING TOOL.

IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PLACE THE INFORMATION

IN THIS MANUAL INTO THE HANDS OF THE OPERATOR.

FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.

•Always operate, inspect and maintain this tool in accordance with all regulations (local, state, federal and country), that may apply to hand held/hand operated pneumatic tools.

•For safety, top performance, and maximum durability of parts, operate this tool at 90 psig

(6.2 bar/620 kPa) maximum air pressure at the inlet with 3/8” (10 mm) inside diameter air supply hose.

•Always turn off the air supply and disconnect the air supply hose before installing, removing or adjusting any accessory on this tool, or before performing any maintenance on this tool.

•Do not use damaged, frayed or deteriorated air hoses and fittings.

•Be sure all hoses and fittings are the correct size and are tightly secured. See Dwg. TPD905-1 for a typical piping arrangement.

•Always use clean, dry air at 90 psig maximum air pressure. Dust, corrosive fumes and/or excessive moisture can ruin the motor of an air tool.

•Do not lubricate tools with flammable or volatile liquids such as kerosene, diesel or jet fuel.

•Do not remove any labels. Replace any damaged label.

USING THE TOOL

•Always wear eye protection when operating or performing maintenance on this tool.

•Always wear hearing protection when operating this tool.

•Keep hands, loose clothing, long hair and jewelry away from working end of tool.

•Note the position of the reversing lever before operating the tool so as to be aware of the direction of rotation when operating the throttle.

•Anticipate and be alert for sudden changes in motion during start up and operation of any power tool.

•Keep body stance balanced and firm. Do not overreach when operating this tool. High reaction torques can occur at or below the recommended air pressure.

•Tool shaft may continue to rotate briefly after throttle is released.

•Air powered tools can vibrate in use. Vibration, repetitive motions or uncomfortable positions may be harmful to your hands and arms. Stop using any tool if discomfort, tingling feeling or pain occurs. Seek medical advice before resuming use.

•Use accessories recommended by Ingersoll-Rand.

•Use only impact sockets and accessories. Do not use hand (chrome) sockets or accessories.

•Impact wrenches are not torque wrenches. Connections requiring specific torque must be checked with a torque meter after fitting with an impact wrench.

•This tool is not designed for working in explosive atmospheres.

•This tool is not insulated against electric shock.

•Prevent exposure and breathing of harmful dust and particles created by power tool use:

Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

-lead from lead based paints,

-crystalline silica from bricks and cement and other masonry products, and

-arsenic and chromium from chemically

treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

The use of other than genuine Ingersoll-Rand replacement parts may result in safety hazards, decreased tool performance, and increased maintenance, and may invalidate all warranties.

Repairs should be made only by authorized trained personnel. Consult your nearest Ingersoll-Rand Authorized Servicenter.

Refer All Communications to the Nearest Ingersoll-Rand Office or Distributor.
