Makita · Power Tool Manual
Abnormal vibration can occur if the drive system is not working correctly.
Click steps to track your progress.
Turn the tool off, unplug it from the power source, wait 30 seconds, then plug it back in and restart the tool.
Carefully inspect the area around the drive system for any visible debris, loose screws, or damage. Remove any obstructions if safe to do so.
Ensure the power cord is securely plugged into a working electrical outlet and that the cord itself is not damaged.
If the vibration is accompanied by unusual grinding noises, smoke, or a burning smell, stop using the tool immediately.
If the abnormal vibration continues after these steps, stop using the tool and contact Makita customer support or a qualified service technician.
