2. Setup and Assembly
Your Jorgensen Cabinet Master clamps come pre-assembled for standard clamping operations. Follow these instructions for initial setup and conversion to spreader mode.
2.1 Standard Clamping Setup
- Ensure the sliding head is positioned with the clamping face towards the fixed jaw.
- Place the workpiece between the jaws.
- Adjust the sliding head close to the workpiece.
- Tighten the handle to apply clamping pressure.
2.2 Converting to Spreader Clamp
The Cabinet Master clamps can be easily converted for spreading applications. This involves reversing the sliding head on the bar.
- Locate the retaining ring or pin at the end of the bar opposite the fixed jaw.
- Remove the retaining ring/pin to allow the sliding head to be removed from the bar.
- Slide the movable jaw off the bar.
- Reverse the movable jaw so its clamping face points away from the fixed jaw.
- Slide the reversed movable jaw back onto the bar.
- Re-secure the retaining ring/pin at the end of the bar.

3. Operating Instructions
3.1 Applying Clamping Pressure
- Position the workpiece securely on a stable surface.
- Open the clamp jaws wider than your workpiece.
- Place the fixed jaw against one side of the workpiece.
- Slide the movable jaw until it makes contact with the other side of the workpiece.
- Rotate the handle clockwise to tighten the clamp and apply the desired pressure. The parallel jaws ensure even pressure distribution.

3.2 Using the Built-in Clamp Stand
The integrated clamp stand allows the clamps to stand upright on a workbench, facilitating one-handed operation and easier positioning of workpieces.
- Simply place the clamp on its side on a flat surface. The stand will support the clamp, keeping the bar elevated.
- This feature is particularly useful when gluing up panels or assembling cabinets, allowing you to hold the workpiece with one hand while adjusting the clamp with the other.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Jorgensen Cabinet Master clamps.
- Cleaning: After each use, wipe down the steel bar and jaws with a clean, dry cloth to remove sawdust, glue, and other debris.
- Lubrication: Periodically apply a light coat of machine oil or dry lubricant to the screw mechanism and the sliding surfaces of the bar to ensure smooth operation. Avoid over-lubricating, as this can attract dust.
- Storage: Store clamps in a dry environment to prevent rust. Hang them or store them flat to prevent warping of the bar over time.
- Inspection: Regularly inspect the clamps for any signs of wear, damage, or loose components. Replace any worn or damaged parts immediately.
5. Troubleshooting
If you encounter issues with your Jorgensen Cabinet Master clamps, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Jaws not parallel / Workpiece bowing | Uneven pressure application; debris in jaw mechanism. | Ensure workpiece is flat and jaws are clean. Apply pressure gradually and evenly. |
| Difficulty sliding movable jaw | Accumulation of dust/debris; lack of lubrication; rust. | Clean the bar and sliding mechanism thoroughly. Apply a light lubricant to the bar. Remove any rust with fine-grit sandpaper and re-lubricate. |
| Handle is stiff or hard to turn | Screw mechanism is dry or dirty. | Clean the screw threads and apply a suitable lubricant. |
| Clamp not holding pressure | Worn screw threads or internal mechanism. | Inspect the screw and internal components for wear. If significantly worn, contact Jorgensen customer support for replacement parts or service. |
