• 90° Swivel Handle: Allows for increased leverage during tightening, reducing user effort.
• 360° Rotating Handle: Prevents the handle from obstructing the rail during clamping, especially in tight spaces.
• High Clamping Force: Capable of achieving up to 5,000 N (approximately 1,124 lbs) of clamping pressure.
• Dimensions: 500mm rail length and 120mm throat depth.

4. Setup

The Bessey GZ50-12KG screw clamp requires minimal setup before use. Ensure the clamp is clean and free of debris.

1. Unpack the clamp: Carefully remove the clamp from its packaging.
2. Inspect for damage: Before first use, visually inspect the entire clamp for any manufacturing defects or shipping damage.
3. Familiarize yourself with components: Identify the fixed jaw, sliding jaw, rail, spindle, and handle.

5. Operating Instructions

Follow these steps for effective and safe operation of your Bessey GZ50-12KG screw clamp:

1. Position the Workpiece: Place the material to be clamped between the fixed and sliding jaws. Ensure the workpiece is stable and supported.
2. Adjust the Sliding Jaw: Loosen the sliding jaw by rotating the handle counter-clockwise slightly, then slide it along the rail until it is close to the workpiece.
3. Apply Clamping Force: Rotate the handle clockwise to tighten the spindle and apply clamping force. The ergonomic 2-component handle provides a comfortable grip.
4. Utilize Swivel Handle for Leverage: For increased leverage and easier tightening, especially when high clamping force is required, the handle can be swiveled 90 degrees.

5. Adjust Handle Position in Tight Spaces: If the handle interferes with the rail or surrounding objects during tightening, it can be rotated 360 degrees while swiveled. This allows for continuous tightening without obstruction.
6. Release Clamping Force: To release the clamp, rotate the handle counter-clockwise until the pressure is relieved and the sliding jaw can be moved freely.
