Setup
The Park Tool TWS-3 is ready for immediate use. No assembly is required. Before each use, inspect the wrench for any signs of damage or wear. Ensure the Torx heads are clean and free of debris to ensure proper engagement with fasteners.
Operating Instructions
- Select Correct Size: Identify the appropriate Torx head size (T10, T25, or T30) that matches the fastener you intend to work with. Using the incorrect size can damage both the fastener and the tool.
- Insert Wrench: Firmly insert the selected Torx head into the fastener, ensuring full engagement. The wrench should sit snugly in the fastener head.
- Apply Torque: Rotate the wrench clockwise to tighten or counter-clockwise to loosen. Apply steady, controlled pressure. Avoid sudden jerking motions.
- Observe Torque Specifications: When tightening, always refer to the component manufacturer's recommended torque specifications. While this wrench provides leverage, it is not a torque-measuring device. Overtightening can strip threads or damage components.
- Note on Twist Prevention Screws: This tool is not designed for use with twist prevention screws. Attempting to use it on such fasteners may result in damage to the fastener or the tool.
Maintenance
- Cleaning: After each use, wipe the wrench clean with a dry cloth to remove dirt, grease, or grime. For stubborn residue, a mild degreaser can be used, followed by thorough drying.
- Storage: Store the wrench in a dry environment, away from direct sunlight and extreme temperatures. Proper storage helps prevent corrosion and extends the tool's lifespan.
- Inspection: Periodically inspect the Torx heads for signs of wear, rounding, or damage. A worn tool can damage fasteners. Replace the tool if significant wear is observed.
Troubleshooting
Most issues with a simple hand tool like the TWS-3 are related to improper use or wear. Consider the following:
- Fastener Slipping: Ensure the correct Torx size is selected and fully engaged. If the fastener head is stripped, the wrench will not be able to grip it.
- Tool Damage: If the wrench head appears rounded or bent, it indicates excessive force or improper use. Replace the tool to prevent damage to fasteners.
- Stuck Fastener: For very tight fasteners, apply penetrating oil and allow it to soak. Ensure you are turning in the correct direction (lefty-loosey, righty-tighty).
