⚠ Band Saw Safety

Turn the band saw OFF and unplug it before performing any maintenance, changing the blade, or adjusting blade tension. Never work on the tensioning mechanism or blade while the machine is connected to power.

Wear cut-resistant gloves when handling the blade. Band saw blades have sharp teeth along the entire length and can cause serious cuts even when the machine is off.

Wear safety glasses at all times when working on or operating the band saw.

Do not over-tension the blade. Excessive tension beyond the machine's rated capacity can cause blade breakage or damage to the saw's frame and tensioning components. Always stay within the manufacturer's recommended range.

Verify all guards and doors are fully closed and secured before reconnecting power and resuming operation after any maintenance or blade change.

Proper blade tension is critical for band saw performance, particularly when using wider resaw blades. Both the Alpha HW615 and Ambassador C14 are capable of delivering approximately:

Maximum Blade Tension ~47,500 PSI

This provides the stability needed for straight, accurate cuts and reduced blade deflection during heavy resawing.

Measuring Blade Tension

The tool shown below is a Lenox Bandsaw Blade Tension Gauge — one of many options available from various distributors. These gauges come in different formats and units of measurement (e.g., PSI, bar), so choose one that suits your specific needs.

Proper Tensioning Instructions

Consult Your Tension Gauge Manual

Review the tension gauge's user manual for setup procedures and calibration instructions before use.

Calculate Required Tension

Determine the correct tension based on the width and thickness of the blade you are using. Wider blades require higher tension.

✓

Adjust and Verify

Adjust the band saw's tensioning mechanism until the desired pressure is reached. Always verify tension settings before operating, especially when switching blade type or size.

For best results, follow both the blade manufacturer's and tension gauge manufacturer's recommendations for your specific blade.
