Hva dette symptomet betyr

Med bladet fritt for materiale, går sagen ujevnt, endrer hastighet gjentatte ganger, eller kan ikke nå sin normale jevne tomgangslyd.

Sannsynlige rotårsaker

  • Battery is weak, temperature-protected, loose, or making poor contact
  • Blade or lower guard is rubbing because of incorrect assembly or damage
  • Vents are blocked and the motor/electronics are overheating
  • Trigger, electronic module, motor, bearings, or gear drive is failing

Raske kontroller

  1. The blade accelerates promptly to a steady normal no-load sound and remains free of rub, surging, and intermittent power.

Reparasjonsforhåndsvisning

  1. Release the trigger, wait for the blade to stop, remove the battery, and do not make a cut while no-load speed is unstable.
  2. - Inspect the battery fit, contacts, blade clamp stack, guard clearance, and vents - correct dry debris, visible rub, or assembly error.
  3. Hand-turn the blade with the battery removed to check for smooth free rotation without scraping, then install a known-good fully charged compatible pack.
  4. Make one brief no-load run with the blade clear and listen for steady acceleration and speed.
  5. If surging, intermittent power, or low no-load speed remains, stop use and route the saw for authorized switch, electronic, motor, bearing, and gear-drive
