Symptoms

  • Little or no air coming from the nozzle end
  • Motor sounds like it's straining
  • Airflow was fine until a stick or debris got pulled in
  • Rattling sound of something loose inside the tube

Likely causes

  • CommonStick or debris lodged inside the tubeTwigs or clumped leaves can get pulled partway in and jam the airway.
  • CommonWet leaves packed inside the tubeDamp debris can mat together and block the narrow tube passage.
  • PossibleTube sections not properly connectedA gap between tube sections can reduce airflow pressure even without a clog.
  • PossibleDebris jammed at the fan/impeller before the tubeA blockage further back at the fan housing can mimic a tube clog.

What to do

  1. Turn off and unplug or remove the battery before attempting to clear any blockage.
  2. Visually inspect both ends of the tube for visible obstructions.
  3. Use a long, thin stick or piece of wire to gently push debris through from one end, working from whichever end is closer to the blockage.
  4. Tap the tube against a soft surface to help dislodge packed material.
  5. Check that all tube sections are fully seated and locked together.
  6. If the blockage is deeper toward the fan housing, remove the tube and check the impeller area for lodged debris.
  7. Test airflow at low speed once cleared before returning to full-speed use.
