诊断概览

motor 正常運作,但集成工作燈唔亮、同穩定嘅battery一齊閃爍,或者亮得比正常扳機後延遲時間耐。

可能根本原因

  • Worklight lens or opening is packed with sawdust
  • Battery or trigger input is intermittent
  • LED, light wiring, or electronic timing control has failed
  • Normal delay of about 20 seconds is being mistaken for a fault

快速检查

  1. The worklight illuminates steadily with trigger operation and turns off automatically after its normal delay.

维修预览

  1. - Confirm the motor operates normally and time the light only after the trigger is fully released - a delay of about 20 seconds is normal.
  2. Remove the battery and clean the light opening and surrounding external area with a dry brush or clean dry air.
  3. Install a known-good fully charged compatible pack and repeat a brief no-load trigger-and-release check.
  4. If the motor remains normal but the light still fails, flickers, or remains on abnormally, leave the housing closed and request authorized light or control
