Using the Makita XCS01T1 rebar cutter is quite straightforward. First, make sure you've inserted a fully - charged 18V LXT Lithium - Ion battery. The battery has an LED indicator to show you the charge level. Once the battery is in, you're ready to start cutting. Adjust the stopper to hold the rebar at a 90 - degree angle to the blade for smooth cuts. The 360 - degree rotatable cutting head allows you to choose the best cutting position. You can cut rebar from 1/8 In. to 3/4 In. thick. For #6 (3/4 In.) rebar, it only takes 6.5 seconds. As for maintenance, after each use, wipe the cutter clean. Check the blade regularly. The blade can make up to 4,000 cuts of #3 (3/8 In.) rebar before it needs replacing. Also, always use genuine Makita batteries and chargers. Remember, there's a 3 - year limited warranty on the tool, battery, and charger. Keep the tool in a dry place when not in use to avoid any damage.
