- Direction Control: Ensure the forward/reverse selector (if present on your tool) is set to the desired direction before operating the trigger.
- Lock-off Button: Some tools may have a lock-off button to prevent accidental starting. Ensure this button is disengaged before pressing the trigger.
6. Maintenance
