Maintenance Tips

• Inspect Before Each Use: Check the power cord, sanding belt, guards, and hardware to ensure everything is secure and undamaged before operating the machine.

• Keep Belts Clean & Replace When Worn: Clean sanding belts regularly and replace them when the abrasive becomes dull, clogged, or damaged to maintain efficient sharpening.

• Remove Dust Build-Up: Vacuum or brush away metal dust, wood dust, and debris from the motor housing and machine components to prevent overheating and maintain performance.

• Check Belt Tracking & Alignment: Ensure the sanding belt runs straight and properly aligned on the wheels to avoid uneven wear and improve sharpening precision.

• Store Abrasive Belts Properly: Keep sanding belts flat in a dry environment—extreme heat, dryness, or humidity can weaken the abrasive bond and reduce belt life.

• Avoid Unnecessary Lubrication: The machine’s ball bearings are factory-sealed and pre-greased, so additional lubrication is not required.

• Disconnect Power Before Maintenance: Always turn off and unplug the machine before cleaning, adjusting belts, or performing any maintenance.
