Cordless vacuum emits a burning smell or hot plastic odor during operation

Safety first: Immediately turn OFF the vacuum, remove the battery pack, and allow the unit to cool. Do not continue using it until the cause is found.

• Inspect brush roll: Remove the nozzle bottom plate and clear all hair and string from the brush roll and end caps. Ensure the brush spins freely by hand.
• Check belt: If your Hamilton Beach model uses a belt, inspect it for melting, glazing, or burning. Replace if damaged.
• Clean vents: Clear dust from all motor and body vents with a soft brush.
• Smell source: Determine if the smell comes from the nozzle (belt/brush) or main body (motor). If from the motor area and persists, discontinue use and have the motor assembly inspected and replaced if necessary.
