Vacuum emits a burning smell while running.

Safety first: Immediately release the trigger, remove the battery, and do not continue using the vacuum until the cause is identified.

• Check for blockages: Inspect the floor nozzle, extension pipe, dust cup, and filters for clogs. Clear all obstructions.
• Inspect motor intake: With the dust cup removed, look into the motor intake for foreign objects touching the fan. Remove any visible debris with a non-metallic tool.
• Smell after cooling: Allow the unit to cool for at least 30 minutes, then briefly run it (with battery installed) and smell near the vents. If the burning smell returns quickly, stop use.
• Do not ignore persistent odor: A continuous burning smell indicates motor or PCB damage and presents a fire risk. The motor housing assembly should be replaced by a Makita service center.
