Vacuum emits an unusual chemical or plastic smell when first used or after long storage.

Safety first: If the smell is very strong, acrid, or accompanied by smoke, stop use immediately and treat as a burning smell fault.

• 1. Ventilate: Use the vacuum in a well-ventilated area for short periods to allow new-plastic odors to dissipate.
• 2. Clean filters and bin: Dust or packaging residue can cause odors when heated. Clean according to the manual.
• 3. Monitor: Mild odors should diminish after several uses. If the smell worsens or is clearly electrical, discontinue use and seek service.
