Belt Removal, Installation & Tensioning Instructions

Applicable Models

Alpha HW110LC (2HP)

Alpha HW110TC (3HP)

Overview

If you are experiencing any of the following symptoms, the most likely cause is a loose motor pulley belt. Applying more tension to the belt should resolve these issues:

Loss of cutting power, especially when the blade is lowered

Squealing or screeching due to belt slippage

Excess vibration in the motor or pulley belt

⚠ Safety — Belt Maintenance

Ensure the machine is OFF, unplugged, and fully de-energized before loosening any cap screws or working inside the cabinet.

Never place hands or fingers near the belt or pulleys while the machine is running. When testing after adjustment, keep all body parts clear of rotating components to prevent pinching or serious injury.

Do not overtighten the belt. Excessive tension puts unnecessary load on the motor and arbor bearings and can cause premature wear or failure.

Wear safety glasses when working inside the cabinet — debris or a snapping belt can cause eye injury.

Belt Tensioning Procedure

Saw must be OFF, unplugged, and fully de-energized

Loosen the cap screw on the motor's belt tensioning point as shown in the diagram below.

Apply pressure to the motor until the belt is tight with minimal play. While maintaining pressure, tighten the cap screw to hold the tension.

✓

Start the motor and test for improvement. If symptoms are resolved, no further action is needed.

If the Issue Persists — Inspect & Clean the Pulleys

Loosen the cap screw to release all tension from the belt. Remove the belt and inspect it for any damage, cracking, glazing, or wear. Replace if integrity is compromised.

Clean both pulleys with a clean cloth and a degreaser such as acetone or odorless mineral spirits. Grease or oil contamination on the pulleys can cause the belt to slip at startup. Wipe completely dry before reinstalling the belt.

Reinstall the belt on the pulleys, apply tension until there is minimal play, and tighten the motor tensioner cap screw to hold the tension.

✓

Start the machine and test for improvement.
