2. General Safety Information

WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

Work Area Safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
• Stay alert, watch what you are doing, and use common sense when operating a power tool.

5. Operating Instructions

5.1 Powering On/Off

To power on the tool, press the trigger. Release the trigger to turn it off. The tool features a variable speed trigger, allowing you to control the speed by how much you depress the trigger.

5.2 Selecting Speed and Torque

The Alloyman Impact Wrench offers three speed/torque settings for versatility:

• Low (159 N.m / 0–1050 RPM): For delicate tasks or initial loosening/tightening.
• Medium (590 N.m / 0–1500 RPM): Suitable for general repairs and common fastening needs.
• High (2000 N.m / 0–2100 RPM): For heavy-duty applications, such as removing rusted truck lug nuts or industrial bolts.

Use the speed selector switch located on the tool to cycle through these settings.
