Belt Information & Tensioning Instructions

Applicable Model

Alpha HW110S Series Table Saws (4HP)

Overview

If you're experiencing any of the following issues, the drive belt likely needs to be tensioned. This adjustment resolves most belt-related performance problems and is straightforward to perform.

Symptoms of a Loose Belt

Loss of cutting power or reduced blade speed under load

Blade stopping or bogging down during cuts

Excessive vibration at shutdown

Belt squeal or screeching at startup

⚠ Table Saw Safety

Ensure the machine is OFF, unplugged, and fully discharged before attempting any belt maintenance to avoid electrical hazards. The motor may still be warm after recent use.

Never place hands or fingers near the belt or pulleys while the machine is running. When checking belt tension or 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 bearings and arbor bearings and can cause premature wear or failure.

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

Apply downward pressure on the motor to increase belt tension, then retighten the bolt to lock the motor in its new position. This increases tension on the belt and prevents slipping and squealing.
