4. Setup

1. Unpack: Carefully remove the impact wrench and all accessories from the packaging. Inspect for any shipping damage.
2. Air Supply Connection:
   • Ensure your air compressor is capable of providing the required air pressure and volume (refer to specifications).
   • Install the quick connector (if not already installed) onto the air inlet of the impact wrench.
   • Connect a 1/2-inch air hose from your air compressor to the quick connector on the tool. Ensure the connection is secure and free of leaks.
   • It is recommended to use an air filter/regulator/lubricator (FRL) unit in your air line to ensure clean, dry, and lubricated air supply, which prolongs tool life.
3. Lubrication: Before first use, and regularly thereafter, add a few drops of pneumatic tool oil into the air inlet. This lubricates the internal components.
4. Socket Attachment: Select the appropriate impact-rated socket for your application. Push the socket firmly onto the 1-inch square drive anvil until it locks securely.

5. Operating Instructions

1. Power On Air Supply: Turn on your air compressor and adjust the air pressure to the recommended operating pressure (refer to specifications).
2. Select Rotation Direction: Use the forward/reverse switch located near the handle to select the desired rotation direction (tighten or loosen).
3. Adjust Torque/Speed: The tool features a 6-step power management system. Adjust the setting to control the output torque and speed according to the fastener and application requirements. Start with a lower setting and increase if more power is needed.
4. Position the Tool: Place the socket squarely onto the fastener. Ensure a firm grip on the tool with both hands, utilizing the D-handle for stability.
5. Engage Trigger: Slowly depress the trigger to begin operation. The tool will deliver impacts to the fastener.
6. Monitor Progress: Observe the fastener. For tightening, stop when the desired tightness is achieved. For loosening, continue until the fastener breaks free.
7. Release Trigger: Release the trigger to stop the tool.
8. Disconnect: When finished, or before changing sockets, always disconnect the air supply.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your impact wrench.

• Lubrication: Add 5-10 drops of pneumatic tool oil into the air inlet before each use, or at least once daily if used frequently. This lubricates the motor and impact mechanism.
• Air Filter: Regularly check and clean or replace the air filter in your air supply system to prevent contaminants from entering the tool.
• Cleaning: Keep the tool clean and free of dirt, dust, and debris. Wipe down the exterior with a clean cloth. Do not use harsh solvents.
• Inspect Hoses and Connections: Periodically check air hoses and connections for wear, cracks, or leaks. Replace damaged components immediately.
• Anvil and Retainer Ring: Inspect the square drive anvil and retainer ring for wear. Replace if they show signs of excessive wear or damage to ensure proper socket retention.
• Storage: Store the tool in a dry, clean environment when not in use. Disconnect from air supply.
