1. Important Safety Instructions
Always observe basic safety precautions when using electrical tools to reduce the risk of fire, electric shock, and personal injury. Read all instructions before operating this tool.
- Work Area Safety: Keep your 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. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Personal Safety: Always wear eye protection. Use safety glasses or goggles. Wear hearing protection when operating power tools for extended periods. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
- 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. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

3. Setup
Before operating the impact wrench, ensure it is properly set up and all safety precautions are followed.
- Unpacking: Carefully remove the impact wrench and all accessories from the carrying case. Inspect for any damage that may have occurred during shipping.
- Socket Selection: Choose the appropriate impact socket for the fastener you intend to work with. Ensure the socket size matches the fastener head precisely to prevent stripping.
- Attaching the Socket: Align the square drive of the impact socket with the 1/2-inch square drive anvil on the impact wrench. Push the socket firmly onto the anvil until it locks securely in place. Some anvils may have a detent pin or friction ring to hold the socket.
- Power Connection: Ensure the impact wrench's power cord is free from damage. Plug the 110-volt power cord into a grounded electrical outlet.
4. Operating Instructions
Follow these steps for safe and effective operation of your impact wrench.
- Direction Control: Locate the forward/reverse rocker switch, typically near the trigger. Push the switch to the 'F' position for forward (tightening) rotation or 'R' for reverse (loosening) rotation. Ensure the switch is fully engaged in the desired direction before starting the tool.
- Positioning the Tool: Place the attached impact socket squarely onto the fastener. Hold the tool firmly with both hands if necessary, maintaining a stable grip.
- Starting the Tool: Depress the trigger switch to start the impact wrench. The tool will begin to rotate and apply impact force.
- Tightening/Loosening: For tightening, allow the tool to impact until the fastener is snug. Avoid over-tightening, which can damage fasteners or materials. For loosening, allow the tool to impact until the fastener breaks free and can be removed.
- Stopping the Tool: Release the trigger switch to stop the impact wrench.
- Removing the Socket: Disconnect the tool from the power source. Pull the socket firmly off the anvil.
