Setup Instructions
- Air Supply Connection:
Connect the tool to a clean, dry, regulated compressed air supply. Ensure the air pressure is within the recommended range (typically 90 PSI / 6.2 bar). Use an air hose with an adequate diameter to ensure proper airflow.
- Lubrication:
Before first use, and regularly thereafter, apply a few drops of pneumatic tool oil into the air inlet. This lubricates the internal components and extends tool life.
- Mandrel and Anvil Installation (if not pre-installed):
Ensure the correct size mandrel and anvil are securely installed for the 1/4-20 inserts. Refer to the tool's specific diagram for proper assembly. Tighten all components firmly.
- Depth Adjustment:
Adjust the depth setting collar to achieve the desired flushness or protrusion of the installed insert. Test on a scrap piece of material before final application.
Operating Instructions
- Prepare the Workpiece:
Drill a hole of the correct diameter for the 1/4-20 insert in the material. Ensure the hole is clean and free of debris.
- Load the Insert:
Thread the 1/4-20 insert onto the tool's mandrel until it is snug against the anvil.
- Position the Tool:
Place the insert into the prepared hole in the workpiece. Ensure the tool is held perpendicular to the surface.
- Install the Insert:
Press the trigger to activate the tool. The mandrel will spin, pulling the insert into the material and deforming it to create a secure thread. Continue until the insert is fully seated and the tool stalls or reaches the set depth.
- Retract the Mandrel:
Release the trigger. Press the reverse button (if applicable) or allow the tool to automatically reverse, then carefully withdraw the tool from the newly installed insert.
- Inspect Installation:
Visually inspect the installed insert to ensure it is flush and securely fastened.
Maintenance
- Daily Lubrication: Add 5-10 drops of pneumatic tool oil into the air inlet before each use or at the start of each shift.
- Cleanliness: Keep the tool clean and free of dirt, dust, and debris. Wipe down the exterior with a clean cloth.
- Air Filter/Regulator: Regularly check and drain moisture from your air compressor's filter/regulator. Ensure the air supply is clean and dry.
- Mandrel/Anvil Inspection: Periodically inspect the mandrel and anvil for wear or damage. Replace worn components to ensure proper insert installation.
- Storage: Store the tool in a dry, clean environment when not in use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool not operating or low power. | Low air pressure; insufficient air flow; lack of lubrication; clogged air inlet. | Check air pressure and hose size; add pneumatic tool oil; clean air inlet. |
| Insert not installing correctly (e.g., not fully collapsing). | Incorrect mandrel/anvil size; worn mandrel/anvil; incorrect depth setting; insufficient air pressure. | Verify mandrel/anvil size; replace worn parts; adjust depth setting; check air pressure. |
| Tool jams or struggles to retract. | Insert over-installed; damaged insert; mandrel stuck. | Adjust depth setting; ensure inserts are not damaged; inspect mandrel for wear. |
