Introduction
Thank you for choosing the Wolfcraft 6176000 Quick Clamps. This set of two quick clamps is designed for efficient and secure fastening of workpieces on workbenches and clamping tables equipped with a 20 mm hole pattern. These clamps are suitable for workpieces up to 35 mm in thickness or diameter, providing a reliable hold for various tasks.
Please read this manual carefully before using the clamps to ensure safe and optimal performance. Keep this manual for future reference.
Safety Information
Always observe general safety precautions when working with tools and workpieces. Failure to do so may result in injury or damage to property.
- Ensure the workbench or clamping table is stable and securely positioned before use.
- Verify that the clamps are fully inserted into the 20 mm bore holes and are properly engaged.
- Do not overtighten the clamps, as this may damage the workpiece or the clamps themselves.
- Always check the stability of the clamped workpiece before beginning any work.
- Keep hands and fingers clear of moving parts during clamping and unclamping operations.
- Use appropriate protective equipment, such as safety glasses, when working.
Setup
The Wolfcraft 6176000 Quick Clamps are designed for use with workbenches and clamping tables featuring a 20 mm hole pattern.
- Identify Bore Holes: Locate the 20 mm bore holes on your workbench or clamping table.
- Insert Clamp: Insert the cylindrical shaft of the quick clamp into the desired 20 mm bore hole. Ensure the clamp is fully seated within the hole.
- Position for Workpiece: Place the workpiece on the workbench. Position the clamps so that the eccentric lever can engage with the workpiece effectively.

Operating Instructions
The eccentric lever design allows for quick and secure fastening.
- Place Workpiece: Position your workpiece on the workbench between the clamps or against a fixed stop and the clamps.
- Engage Clamp: With the clamp inserted into a 20 mm bore hole, rotate the eccentric lever towards the workpiece. The eccentric shape of the lever will apply pressure, securing the workpiece.
- Secure Fastening: Continue to twist the lever until the workpiece is held firmly and without movement. The clamps are designed to hold workpieces up to 35 mm in thickness or diameter.
- Release Workpiece: To release, simply twist the lever in the opposite direction. The eccentric mechanism will disengage, allowing you to remove the workpiece.

Maintenance
Proper maintenance ensures the longevity and reliable performance of your Wolfcraft Quick Clamps.
- Cleaning: After each use, wipe the clamps clean with a dry cloth to remove dust, sawdust, or debris.
- Lubrication: Periodically apply a small amount of light machine oil to the pivot points of the eccentric lever to ensure smooth operation.
- Storage: Store the clamps in a dry environment to prevent corrosion.
- Inspection: Regularly inspect the clamps for any signs of wear, damage, or deformation. Do not use damaged clamps.
Troubleshooting
If you encounter issues with your Wolfcraft Quick Clamps, refer to the following common problems and solutions:
- Clamp does not hold workpiece securely:
- Ensure the clamp is fully inserted into the 20 mm bore hole.
- Verify the workpiece thickness or diameter is within the 35 mm limit.
- Check if the eccentric lever is fully rotated to the locked position.
- Inspect the clamp for any damage or wear that might affect its gripping ability.
- Clamp is difficult to insert or remove from bore hole:
- Ensure the bore hole is clean and free of debris.
- Check if the bore hole size is exactly 20 mm.
- Apply a small amount of lubricant to the shaft of the clamp if resistance persists.
