3. Setup
Proper setup is crucial for the safe and efficient operation of your Steelman 102-4 Impact Wrench.
Air Supply Connection:
- Prepare Air Line: Ensure your air compressor is capable of providing a continuous air supply at the recommended pressure and volume. The tool requires 4 CFM at 90 PSI.
- Install Air Coupler: Apply thread sealant tape to the male threads of the air coupler (not included) and thread it into the air inlet of the impact wrench.
- Connect Air Hose: Connect a suitable air hose (minimum 3/8-inch inner diameter) to the air coupler. Ensure all connections are secure and leak-free.
- Install Air Filter/Regulator/Lubricator (FRL) Unit: For optimal performance and tool longevity, install an FRL unit in your air line, as close to the tool as possible. This unit filters moisture and debris, regulates air pressure, and provides lubrication.
- Lubrication: If an automatic lubricator is not used, add 5-10 drops of pneumatic tool oil into the air inlet before each use.
Socket Installation:
- Select Correct Socket: Choose an impact-grade socket of the correct size for the fastener. Do not use chrome sockets, as they are not designed for impact use and may shatter.
- Attach Socket: Firmly push the socket onto the 2-inch extended anvil until it locks securely in place.

4. Operating Instructions
Follow these steps for safe and effective operation of your impact wrench.
Before Operation:
- Ensure all safety precautions are observed.
- Verify the air pressure is set to 90 PSI.
- Confirm the socket is securely attached.
Using the Impact Wrench:
- Direction Control: Locate the forward/reverse selector switch, typically near the trigger. Set it to the desired direction (clockwise for tightening, counter-clockwise for loosening).
- Variable Speed Trigger: The tool features a variable speed tease trigger. Squeeze the trigger gently for lower speed and increased control, or fully for maximum power.
- Applying Torque: Place the socket squarely onto the fastener. Apply steady pressure to the tool and gradually squeeze the trigger. Allow the tool to impact until the fastener is tightened or loosened.
- Avoid Over-tightening: For critical applications, always use a torque wrench to achieve the final specified torque after using the impact wrench for initial tightening.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Steelman 102-4 Impact Wrench.
Daily Maintenance:
- Lubrication: Add 5-10 drops of high-quality pneumatic tool oil into the air inlet before each use, or ensure your in-line lubricator is functioning correctly.
- Air Filter: Check and drain the moisture trap on your air compressor and FRL unit daily. Clean or replace the air filter element as needed.
- Clean Tool: Wipe down the tool exterior with a clean cloth to remove dirt and debris.
Periodic Maintenance:
- Inspect Air Hose: Regularly inspect the air hose for wear, cuts, or leaks. Replace damaged hoses immediately.
- Anvil and Retainer: Check the anvil and socket retainer for wear or damage. Replace if necessary to ensure secure socket retention.
- Fasteners: Periodically check all external fasteners on the tool for tightness.
