3. Setup
3.1 Unpacking
- Carefully remove the shear from its packaging.
- Inspect the machine for any signs of shipping damage. Report any damage to your supplier immediately.
- Verify that all components listed in the packing list are present.
3.2 Assembly and Placement
- Position the shear on a sturdy, level workbench or stand capable of supporting its weight (Net Weight: 105 Kg).
- Securely fasten the shear to the workbench using appropriate bolts and nuts to prevent movement during operation.
- Attach the operating handle to its designated pivot point, ensuring it is firmly secured.
- Ensure there is adequate clear space around the machine for safe operation and material handling.
4. Operating Instructions
4.1 Preparing the Material
- Ensure the sheet metal to be cut is clean and free of burrs or obstructions.
- Verify that the material thickness does not exceed 1.5 mm and the width does not exceed 650 mm.
4.2 Adjusting the Back Gauge
The manual back gauge allows for precise control over the cutting length. To adjust:
- Loosen the locking mechanism for the back gauge.
- Slide the back gauge to the desired measurement using the integrated scale (range 0 to 500 mm).
- Tighten the locking mechanism to secure the back gauge in position.
4.3 Cutting Procedure
- Position the sheet metal against the back gauge and the fixed angular stop (if required) on the front.
- Ensure the material is flat and fully supported on the cutting bed.
- Lower the operating handle slowly. The automatic sheet hold-down device will engage, securing the material.
- Continue to lower the handle with steady pressure to execute the cut.
- Once the cut is complete, raise the operating handle to its original position. The hold-down device will release.
- Carefully remove the cut material and any off-cuts.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Holzmann TBS 650PRO shear.
5.1 Cleaning
- After each use, clean the cutting bed and blade area to remove metal shavings and dust.
- Use a brush or compressed air for cleaning. Avoid using harsh chemicals that may damage painted surfaces.
5.2 Blade Care
- Regularly inspect the carbon-chrome steel cutting blade for sharpness and any signs of damage (nicks, dullness).
- A dull blade can lead to poor cut quality and increased effort. If the blade is dull, it should be professionally sharpened or replaced.
- When replacing the blade, ensure it is a genuine Holzmann replacement part for optimal performance and safety.
5.3 Lubrication
- Apply a light machine oil to all pivot points and sliding surfaces periodically to ensure smooth operation.
- Wipe off any excess oil to prevent dust accumulation.
5.4 Storage
- Store the shear in a dry, clean environment to prevent rust and corrosion.
- If storing for an extended period, apply a thin layer of protective oil to exposed metal surfaces, especially the blade.
6. Troubleshooting
This section addresses common issues you might encounter during operation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven or rough cuts | Dull blade, improper material positioning, loose back gauge. | Inspect and sharpen/replace blade. Ensure material is flush against stops. Tighten back gauge. |
| Difficulty operating handle | Material too thick, lack of lubrication, binding mechanism. | Verify material thickness is within limits. Lubricate pivot points. Check for obstructions. |
| Material slips during cut | Hold-down device not engaging properly, material not flat. | Ensure hold-down device is functioning. Position material flat on the bed. |
