Handle or body becomes unusually hot to the touch during operation

Safety first: Switch off, unplug, and allow the unit to cool before further use.

• 1. Clean all filters and vents
  • Remove and clean pre-filters and exhaust filters.
  • Vacuum dust from all ventilation grilles.
• 2. Check for obstructions
  • Ensure hoses and nozzles are not blocked, forcing the motor to work harder.
• 3. Inspect internal wiring (for technicians)
  • Look for discolored or melted connectors that indicate overheating.
  • Repair or replace affected wiring and components.
• 4. Motor evaluation
  • If overheating persists, the motor may be failing and should be replaced by a professional.
