Using the Makita XRV01T is easy. First, make sure you have a fully - charged 18V LXT 5.0 Ah battery. Insert the battery into the tool. You can hold the tool in either a horizontal or vertical position thanks to the dual - directional switch. Once you turn it on, the motor will generate 13,000 vibrations per minute. Place the 4 - foot shaft into the concrete. The 1 - inch thick shaft will help level the concrete and remove air bubbles effectively. Run the tool for up to 41 minutes under load. When it's time to charge the battery, use the Rapid Optimum Charger. It will charge the battery in 45 minutes or less. The charger has a built - in fan to cool the battery and optimize the charging process. Remember, this tool has STAR Protection to prevent overloading, over - discharging, and over - heating. Always use genuine Makita batteries and chargers. After use, clean the tool and store it in a dry place. The tool, battery, and charger come with a 3 - year limited warranty, so you can use it with confidence.
