Using this 18V LXT Handheld Canister Vacuum is easy. First, make sure you have a fully charged 1.5Ah Makita battery (sold separately). Then, choose the right speed from the 3 speed buttons according to the cleaning job. The vacuum can handle a wide range of debris with its 49 CFM motor. The extendable hose lets you reach tight spots. If the L.E.D. warning light on the vacuum turns on, it's time to recharge the battery. When not in use, store the vacuum in a dry place. Keep it clean by emptying the debris regularly. Only use genuine Makita batteries and chargers to ensure good performance and protect the tool from overloading, over-discharging, and overheating. The vacuum comes with a 3-year limited warranty, so if you have any issues, reach out to Makita. And don't forget, it can also be used as a blower with the included attachments for added versatility.
