Pre-Use Activities:                                                               

• Review and understand information provided in the owner’s manual, specifically the safety procedures.
• Inspect the air-impact wrench for damage, disrepair, or missing parts, including assessing the condition of the air hose and associated fittings.
• Assure the air hose and fittings are secured tightly.

Operating Precautions:

• Wear safety glasses with side protectors.
• Never wear a tie, loose clothing, or jewelry (watch, rings, etc.) when using an air-impact wrench.
• Tie long hair back or secure under a cap.
• Wear hearing protection when using this tool; an air-impact wrench creates a noise exposure of about 103 dB.
• Use clean, dry air at the manufacturer’s recommended pressure (about 90 psi) to power the air-impact wrench.
• Use impact wrench sockets that are specifically designed for this type of tool.
• Stop using the air-impact wrench if you experience tingling, numbing, or painful sensations in the hands, fingers, or arms and seek medical attention if the sensations persist. Air-impact wrenches vibrate while being used.
• Use a torque wrench to apply the proper torque to bolts and nuts. Do not over torque bolts and nuts with an air-impact wrench.
• Carry an air-impact wrench by the handle or body; never carry an air impact wrench by the air hose.
• Disconnect the air hose before installing or while performing tool maintenance.

An impact wrench is also known as an air gun, air wrench, or torque gun. They are designed to deliver high torque output, with minimal exertion by the user.

Impact wrenches are widely used in many industries, including auto repair, heavy equipment maintenance, product assembly, and major construction projects. Anywhere high torque output is needed.

Impact wrenches are available in every standard socket wrench drive size, from small 1/4″ drive tools for small assembly and disassembly, up to 3.5″ and larger square drives for major construction. Impact wrenches are one of the most commonly used air tools and are found in virtually every mechanic’s shop.
