Key Features
- Genuine OEM Motor Integrity — Manufactured to Husqvarna's original output and torque specifications, ensuring the arm feeding system operates exactly as engineered — not approximated.
- Direct Assembly Replacement — This assembly is designed to drop into the arm feeding system of compatible wall saws, restoring the original mechanical interface without reworking mounting points.
- Confirmed Wall Saw Compatibility — Fits the WS440, WS482, and WS440HF wall saws, covering both standard and high-frequency variants in the WS series.
- Restored Feed Control — A functioning arm feeding motor maintains consistent blade advancement through the cut, supporting straight, controlled passes and protecting the blade and drive system from uneven loading.
- Electrical Safety Compliance — As a motorized drive component, this OEM assembly meets Husqvarna's original electrical and mechanical safety standards for the WS series, keeping the feed system operating within designed parameters.
The arm feeding motor assembly drives the controlled advancement of the wall saw's cutting head along its track during operation. It regulates how quickly and evenly the blade is fed into the material, which directly affects cut quality, blade life, and operator control. When this motor weakens or fails, the saw may lose consistent feed pressure, resulting in uneven cuts, blade deflection, or a complete loss of powered arm movement — requiring the operator to stop work until the assembly is replaced.
