Setup
Follow these steps to set up your air impact wrench for operation:
- Air Supply Connection: Connect the air impact wrench to a clean, dry, and regulated air supply. The tool requires an NPT 1/4" (6.3mm) air inlet and a 3/8" (9.5mm) air hose. Ensure your air compressor can provide the necessary air consumption of 6.5 CFM at an operating pressure of 0.63 MPa (approximately 90 PSI).
- Lubrication: Before initial use and regularly thereafter, lubricate the tool. The included lubrication adaptor simplifies this process. Add a few drops of pneumatic tool oil into the air inlet or use the adaptor for continuous lubrication. Regular oiling is crucial for prolonging the tool's service life and maintaining optimal performance.
- Attach Socket: Select the appropriate impact-rated socket from the included set and firmly attach it to the 1/2-inch square drive of the impact wrench. For deeper access, use the 5-inch extension bar.

Operating Instructions
Operating your XIIW Air Impact Wrench involves selecting the correct direction and torque setting:
- Direction and Torque Adjustment: Use the F/R (Forward/Reverse) exchange knob located at the rear of the tool to select the desired direction and torque setting. The tool offers:
- Forward Settings:
- Forward 1: 200 ft-lb (271 N·m)
- Forward 2: 1000 ft-lb (1357 N·m)
- Forward 3: 1500 ft-lb (2035 N·m)
- Reverse Setting:
- Reverse: 1560 ft-lb (2116 N·m) (Max loosening torque)
- Applying the Tool: Place the socket firmly onto the fastener. Ensure the tool is stable and you have a firm grip.
- Operation: Press the trigger to activate the impact wrench. Apply steady pressure to the tool. Release the trigger to stop operation.
- Monitoring: For tightening applications, it is recommended to use a torque wrench for final tightening to ensure fasteners are torqued to manufacturer specifications.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your XIIW Air Impact Wrench:
- Lubrication: As mentioned in the setup, regular lubrication is critical. Add a few drops of pneumatic tool oil to the air inlet before each use or every few hours of continuous operation. The lubrication adaptor can assist with this.
- Air Line Maintenance: Ensure your air supply is clean and dry. Water and contaminants in the air line can damage the tool's internal components. Use an air filter/regulator/lubricator (FRL) unit in your air system.
- Cleaning: Keep the exterior of the tool clean. Wipe off any dirt, grease, or oil after use. Do not use harsh solvents that could damage the housing.
- Inspect Connections: Periodically check all air connections for leaks. Tighten fittings as necessary.
- Storage: Store the impact wrench and its accessories in the provided storage case in a dry, clean environment when not in use.
