3. Setup

  1. Air Supply Connection: Connect the impact wrench to a clean, dry, regulated air supply. Ensure the air hose has an internal diameter of at least 3/8 inch (10 mm) and is fitted with a suitable quick-release coupling. The recommended operating pressure is 90 psi (6.2 bar).
  2. Lubrication: Before first use and daily thereafter, add a few drops of air tool oil into the air inlet. This is crucial for the longevity and performance of the tool. The tool is marked "OIL DAILY!" as a reminder.
  3. Initial Check: Before connecting to the air supply, ensure the trigger is not depressed. Once connected, briefly run the tool to confirm proper operation and lubrication.
  4. Socket Attachment: Select the appropriate 1/2" Sq drive impact socket for your application and firmly attach it to the anvil.

4. Operating Instructions

  1. Direction Selection: Use the F/R (Forward/Reverse) selector switch, typically located near the trigger, to choose the desired direction of rotation. "F" is for fastening (clockwise), and "R" is for loosening (counter-clockwise).
  2. Torque Adjustment: The tool features a four-position adjustable air/torque control. This allows you to regulate the power output for different applications. Start with a lower setting and increase as needed to prevent overtightening or damage to fasteners.
  3. Fastening:
    • Set the direction to "F" (Forward).
    • Place the socket firmly onto the fastener.
    • Depress the trigger to operate the tool. Release the trigger to stop.
    • For critical applications, always use a torque wrench to achieve the final specified torque.
  4. Loosening:
    • Set the direction to "R" (Reverse).
    • Place the socket firmly onto the fastener.
    • Depress the trigger to operate the tool. Release the trigger to stop.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Sealey SA2 Air Impact Wrench.

  • Daily Lubrication: Add a few drops of high-quality air tool oil into the air inlet before each use. This lubricates the internal components and prevents corrosion.
  • Air Line Maintenance: Ensure your air compressor's drain valve is opened daily to release accumulated moisture. Regularly check and clean the air filter and lubricator (if installed) in your air supply system.
  • General Cleaning: Keep the tool clean and free from debris. Wipe down the exterior with a clean cloth. Do not use solvents that may damage the rubber or plastic components.
  • Inspection: Periodically inspect the tool for any signs of wear, damage, or loose fasteners. Pay close attention to the anvil, trigger, and air connections. Replace worn or damaged parts immediately.
  • Storage: When not in use, store the impact wrench in a clean, dry, and secure location, away from direct sunlight and extreme temperatures.
