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
- The blade accelerates promptly to a steady normal no-load sound and remains free of rub, surging, and intermittent power.
维修预览
- Release the trigger, wait for the blade to stop, remove the battery, and do not make a cut while no-load speed is unstable.
- - Inspect the battery fit, contacts, blade clamp stack, guard clearance, and vents - correct dry debris, visible rub, or assembly error.
- 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.
- Make one brief no-load run with the blade clear and listen for steady acceleration and speed.
- 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
