Vacuum emits a burning smell or very hot air from the exhaust during use.

Safety first: Switch off the vacuum immediately and remove the battery. Do not continue to use the vacuum if a burning smell persists.

• Step 1 – Allow cooling: Let the vacuum cool for at least 30–60 minutes in a well-ventilated area.
• Step 2 – Clean filters and airflow path: Remove and thoroughly clean or replace all filters. Check for blockages in the nozzle, tube, and dust container.
• Step 3 – Inspect for visible damage: Look through any vents or openings for signs of melted plastic or discoloration near the motor area.
• Step 4 – Test briefly: After cleaning and cooling, reinstall the battery and run the vacuum for 30–60 seconds. If the burning smell returns quickly, stop use.
• Step 5 – Service required: A persistent burning smell indicates motor insulation damage or severe overheating. The motor unit assembly should be replaced by an authorized Severin technician.
