Using this Makita band saw is easy. First, make sure you've got a compatible Makita 18V Lithium - Ion battery with a Star symbol (battery and charger sold separately). Insert the battery, and you're ready to start. Use the variable speed dial and trigger to match the speed to your cutting task. For one - hand operation in tight spaces or overhead work, it's designed to be very handy. When cutting, use the adjustable stopper plate for better material support. Remember to use the catch bar to avoid accidental follow - through during repetitive cuts. As for maintenance, keep the blade clean and sharp. You can use the blade tracking dial to adjust the blade for better cutting performance. Check the battery charge level using the integrated 3 - stage L.E.D. light indicator. Always use genuine Makita batteries and chargers to ensure the saw works well and to protect it from overloading, over - discharging, and over - heating. Also, follow the 3 - year limited warranty terms. And don't forget, only use blades that are 32 - 7/8' x 1/2'.
