Using your Makita GBU01Z blower is a breeze. First, make sure you have a fully - charged 40V max XGT® Lithium - Ion battery (sold separately). Insert the battery into the blower. You can adjust the speed using the variable speed trigger. If you have heavy debris to move, switch to turbo boost mode. Use the cruise control lever to manage power and runtime. The 3 - stage telescoping long nozzle can be adjusted to reach different areas. For continuous operation, use the speed lock. When you're done, hang the blower using the hole at the bottom of the housing for easy storage. Always use genuine Makita® Batteries and Chargers to ensure proper performance and safety. Keep the blower clean and dry. After use, check for any debris in the nozzle and clean it if necessary. Store the blower in a cool, dry place. This blower comes with a 3 - year limited warranty, so if you have any problems, contact Makita customer service.
