1. Safety Instructions
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.
1.1 General Power Tool Safety
- 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.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
- Personal Safety: Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
- Service: Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
1.2 Specific Safety Warnings for Impact Wrenches
- Always wear eye protection and hearing protection when operating an impact wrench.
- Secure the workpiece. Use clamps or a vise to hold the workpiece. This is safer than using your hand and it frees both hands to operate the tool.
- Ensure the socket is correctly fitted and secured before operation.
- Avoid touching the rotating parts during operation.
- Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool.

4.2 Forward/Reverse Rotation
The impact wrench features a switch for selecting forward (tightening) or reverse (loosening) rotation. This switch is typically located near the trigger.
- Forward (Tightening): Push the switch to the 'F' or 'R' (for Right) position. The tool will rotate clockwise.
- Reverse (Loosening): Push the switch to the 'R' or 'L' (for Left) position. The tool will rotate counter-clockwise.

- Hold the tool firmly with both hands if necessary, maintaining a stable grip.
- Press the trigger switch to begin operation. The tool will apply rotational force and impact action to the fastener.
- For tightening, stop when the fastener is snug. Avoid over-tightening, which can damage fasteners or the workpiece. For critical applications, always use a torque wrench for final tightening to specified torque values.
- For loosening, continue until the fastener is free.
- Release the trigger to stop the tool.
CAUTION: The impact action can generate significant force. Be prepared for the tool to react during operation. Do not apply excessive pressure; let the tool do the work.
