Setup and Preparation

The GEARWRENCH combination wrench is ready for immediate use upon receipt. No assembly is required.

Pre-Use Inspection:

• Inspect the wrench for any signs of damage, such as cracks, bends, or excessive wear. Do not use a damaged tool.
• Ensure the wrench size (13mm) matches the fastener you intend to work with. Using an incorrect size can damage both the fastener and the tool.
• Clean any grease or debris from the wrench to ensure a secure grip.

Operating Instructions

This combination wrench is designed for tightening and loosening 13mm metric fasteners (nuts and bolts).

General Use Guidelines:

1. Select the Correct End:
   • Use the open end for quick engagement and disengagement of fasteners, especially when access is limited from the top. The Surface Drive Plus™ design helps prevent rounding.
   • Use the 12-point box end for maximum grip and torque application, particularly when breaking loose stubborn fasteners or for final tightening. The 15-degree offset provides knuckle clearance.
2. Ensure Proper Fit: Always ensure the wrench is fully seated on the fastener. A loose fit can lead to slippage, fastener damage, and potential injury.
3. Apply Force Correctly:
   • Pull on the wrench rather than push, when possible, to reduce the risk of injury if the wrench slips.
   • Apply steady, even pressure. Avoid sudden jerking motions.
   • For stubborn fasteners, apply penetrating oil and allow it to work before attempting to loosen.
4. Leverage: The long pattern length provides increased leverage. Use this advantage for fasteners requiring higher torque, but always be mindful of over-tightening.
5. Safety: Wear appropriate personal protective equipment (PPE), such as safety glasses, when using hand tools.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your GEARWRENCH combination wrench.

• Cleaning: After each use, wipe the wrench clean with a cloth to remove dirt, grease, and grime. For stubborn residue, use a mild degreaser.
• Drying: Ensure the wrench is completely dry before storage to prevent rust, especially in humid environments.
• Storage: Store the wrench in a dry, clean environment, away from corrosive chemicals. A tool roll, drawer, or toolbox is recommended to protect the finish and prevent damage.
• Inspection: Periodically inspect the wrench for any signs of wear, damage, or corrosion. Address any issues promptly.

Troubleshooting

Most issues with a combination wrench can be avoided by following proper usage and maintenance guidelines. However, if you encounter problems:

• Wrench Slipping:
  • Ensure the wrench size matches the fastener exactly.
  • Confirm the wrench is fully seated on the fastener.
  • Check for excessive wear on the wrench jaws or box end. A worn tool should be replaced.
• Fastener Rounding:
  • This often occurs due to using an oversized wrench, a worn wrench, or improper seating.
  • Always use the correct size wrench and ensure it is fully engaged.
  • The Surface Drive Plus™ feature on the open end is designed to minimize rounding; ensure you are utilizing it correctly.
• Tool Damage (Bending/Breaking):
  • Avoid using extension pipes (cheater bars) on wrenches, as this can apply excessive force beyond the tool's design limits and void the warranty.
  • Do not strike the wrench with a hammer or other tools unless it is specifically designed for striking applications (this wrench is not).
  • If the tool is damaged, discontinue use immediately and replace it.
