4. Setup

1. Air Supply Connection:

   Connect the tool to a clean, dry, regulated air supply. The recommended minimum hose size is 1/2 inch. The operating pressure should be 90 PSI (6.2 bar). The air inlet size is 1/2 inch NPT.

   Ensure the air compressor can provide sufficient airflow. The average air consumption is 10 CFM, with 40.7 CFM at load.

2. Lubrication:

   Before initial use, and regularly thereafter, add a few drops of pneumatic tool oil into the air inlet. This lubricates the internal components and extends tool life.

3. Socket Attachment:

   Select the appropriate impact-rated socket for your application. Attach the socket securely to the 1-inch square drive on the extended anvil, ensuring it engages with both the retainer hole and ring.

4. Side Handle Adjustment:

   Adjust the ergonomic side handle to a comfortable and secure position for optimal control and balance during operation.

5. Operating Instructions

1. Direction Control (Forward/Reverse):

   Locate the forward/reverse regulator. Move the regulator to the desired direction for tightening (forward) or loosening (reverse). The tool offers 3 power settings in both directions.

2. Power Adjustment:

   Select the appropriate power setting using the regulator. Start with a lower setting for initial fastening or delicate work, and increase as needed for stubborn fasteners.

3. Engaging the Trigger:

   Hold the tool firmly with both hands, ensuring a stable stance. Press the full teasing inside trigger gradually to control the speed and power of the impact wrench. A light press will result in lower RPM and IPM, while a full press will deliver maximum power.

4. Applying Torque:

   For tightening, apply the socket to the fastener and press the trigger. For loosening, ensure the tool is set to reverse and apply to the fastener. The tool delivers up to 2140 ft.-lbs. of max reverse torque and 1850 ft.-lbs. working torque in forward.

5. Disengaging:

   Release the trigger to stop the tool. Always disconnect the air supply when not in use or when changing sockets.

6. Maintenance

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

• Lubrication:

  Add a few drops of high-quality pneumatic tool oil into the air inlet before each use or at least once daily, depending on usage frequency. This lubricates the motor and extends its life.

• Air Filter:

  Ensure your air supply system has a functional air filter to prevent moisture and debris from entering the tool. Regularly drain moisture from your air compressor tank.

• Cleaning:

  Keep the tool clean and free from dirt and debris. Wipe down the exterior with a clean cloth. Do not use harsh solvents that may damage the housing.

• Inspection:

  Periodically inspect the tool for any signs of wear, damage, or loose fasteners. Pay close attention to the square drive, anvil, and air connections. Replace worn or damaged parts immediately with genuine Chicago Pneumatic replacement parts.

• Storage:

  Store the impact wrench in a dry, clean environment away from extreme temperatures and corrosive materials.
