3. Setup
3.1 Attaching the Auxiliary Grip
- Align the ergonomic auxiliary grip with the mounting holes on the wrench body.
- Insert the provided screws and tighten them securely with an appropriate tool.
3.2 Connecting to Air Supply
- Ensure your air compressor is off and the air line is depressurized.
- Wrap the threads of the included air quick-connect fitting with PTFE tape (not included) for an airtight seal.
- Thread the air quick-connect fitting into the air inlet port (NPT 1/2") on the wrench.
- Connect a 1/2" recommended hose size air line to the quick-connect fitting.
- Set your air compressor regulator to the desired operating pressure, between 90 PSI and 200 PSI.
3.3 Lubrication
Before first use and regularly thereafter, add a few drops of pneumatic tool oil (not included) into the air inlet. This lubricates the internal components and extends tool life.
4. Operation
4.1 Attaching Sockets
Ensure the air supply is disconnected. Push the desired 1-inch square drive socket onto the anvil until it locks securely in place.
4.2 Forward/Reverse and Torque Adjustment
The wrench features an F/R exchange knob for direction and power control. This knob allows you to select between 3 forward power settings and 3 reverse power settings.
- Forward (Tightening): Rotate the knob to one of the 'F' positions (1, 2, or 3) for tightening bolts. Setting 3 provides maximum forward torque.
- Reverse (Loosening): Rotate the knob to one of the 'R' positions (1, 2, or 3) for loosening bolts. Setting 3 provides maximum reverse (nut-busting) torque.

4.3 Operating the Wrench
- Select the appropriate direction (forward or reverse) and torque setting using the F/R exchange knob.
- Place the socket firmly onto the fastener.
- Press the trigger to activate the wrench. The tool will deliver impacts until the fastener is tightened or loosened.
- Release the trigger to stop operation.

5. Maintenance
5.1 Daily Lubrication
Add 5-10 drops of pneumatic tool oil into the air inlet before each use or after every hour of continuous operation. This is crucial for the longevity and performance of the tool.
5.2 Cleaning
Keep the tool clean and free from debris. Wipe down the exterior with a clean, dry cloth. Do not use harsh solvents that may damage the composite body.
5.3 Air Filter and Regulator
Regularly check and clean your air compressor's air filter and water trap to ensure clean, dry air supply to the wrench. Moisture and contaminants can severely damage pneumatic tools.
5.4 Storage
When not in use, disconnect the air supply and store the wrench in a clean, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not operate or operates slowly. | Low air pressure or insufficient air volume. | Check air compressor pressure (ensure 90-200 PSI). Verify hose size (recommended 1/2"). Check for kinks in air hose. |
| Loss of power or reduced torque. | Lack of lubrication. | Add pneumatic tool oil to the air inlet. |
| Air leaks from connections. | Loose fittings or damaged PTFE tape. | Tighten all air connections. Reapply PTFE tape if necessary. |
| Excessive vibration. | Worn internal parts or unbalanced socket. | Ensure socket is properly seated and not damaged. If problem persists, contact customer support. |
