Using the Makita XRJ07ZB reciprocating saw is a breeze. First, make sure you've got a fully - charged 18V LXT Lithium - Ion battery (battery and charger sold separately). Insert the battery into the saw following the instructions. For blade installation, use the tool - free blade change system. Just open the blade clamp, put the blade in place, and close the clamp. To start cutting, hold the saw firmly with the rubberized soft - grip handle. You can adjust the speed from 0 to 3,000 strokes per minute depending on your task. The built - in LED light will help you see the work area clearly. When you're done cutting, use the electric brake to stop the blade quickly. As for maintenance, keep the saw clean. Wipe it down after each use to remove dust and debris. Since it has Extreme Protection Technology (XPT), it can handle some dust and water, but try to avoid using it in extremely wet or dirty conditions. Always use genuine Makita batteries and chargers to protect the saw from overloading, over - discharging, and over - heating. And remember, this saw comes with a 3 - year limited warranty, so take good care of it.
