诊断概览

鋸片未接觸任何材料時,鋸機運行唔均勻,速度反覆變化,或者達唔到正常穩定嘅空載聲音。

可能根本原因

  • 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

快速检查

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

维修预览

  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
