The Worklight Fails, Flickers, Or Stays On Well Beyond Its Normal Delay

The motor operates normally, but the integrated worklight does not illuminate, flickers with a stable battery, or remains lit far longer than the normal post-trigger delay.

• 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

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

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
