The Trigger Or Lock-Off Control Does Not Work Safely

The lock-off will not block or release the trigger, or the trigger sticks or switches unreliably.

• Dry debris obstructs the trigger or lock-off button
• Trigger or lock-off is cracked or impact-damaged
• Trigger return or lock-off spring mechanism has failed
• Liquid or contamination entered the control area
• Internal switch or electronic control fault

1. Qualified repair confirms reliable lock-off, trigger return, start, and stop.

1. Keep the blade clear, release the trigger, and remove the battery.
2. Confirm the trigger returns fully and the lock-off moves freely without force.
3. - Brush away only loose dry debris around the controls - do not add oil or solvent.
4. If either control sticks or operates incorrectly, keep the saw out of service for repair.
