Using this impact wrench is easy. First, make sure you've got a fully charged Makita 18V LXT lithium-ion battery with the star symbol. Insert the battery into the tool. Then, choose the right speed using the 4-speed power selection switch according to your task. For forward or reverse movement, set the appropriate auto-stop mode to avoid over-tightening or over-loosening. Press the trigger, and you're ready to work. The full-speed mode can be used to quickly reach full speed. When not in use, store the tool in a dry place. Clean it regularly to keep dust and debris away, especially from the air vents. Don't use it in extremely wet or dusty conditions without proper protection. Only use genuine Makita batteries and chargers to ensure the best performance and to protect the tool and battery from damage. And remember, this tool comes with a 3-year limited warranty, so take good care of it.
