The worklight is activated by the trigger switch. There is no independent on/off setting. If the tool runs but the light does not illuminate, the LED is likely faulty or there is an internal connection problem.
- First, ensure the battery pack is properly installed and has a charge. A fully depleted battery may not provide enough power for the light.
- Operate the tool in a dim area. The light should illuminate when the trigger is pulled and may remain on for a short delay after release.
If that didn't work, the issue is internal. Do not attempt to disassemble the housing to access the worklight. Never modify the power tool. Damage or personal injury could result.
Heads up: This requires professional repair. Take the tool to an authorized service center for diagnosis and service.
