Cutting Procedure
- Secure the workpiece firmly in a vise or with clamps to prevent movement during cutting.
- Hold the band saw firmly with both hands, ensuring a stable grip.
- Align the blade with the intended cutting line on the workpiece.
- Start the saw and allow the blade to reach full speed before contacting the material.
- Apply steady, even pressure to guide the saw through the material. Do not force the tool.
- Maintain a consistent cutting speed.
- Once the cut is complete, release the trigger and allow the blade to stop completely before setting the tool down.
Maintenance
Blade Replacement
Regularly inspect the blade for dullness, damage, or missing teeth. A dull blade can lead to inefficient cutting and increased strain on the tool. Replace blades as described in the 'Blade Installation' section.
Cleaning
