Using the Makita XBP05ZB is easy. First, make sure you have a fully - charged 18V LXT Lithium - Ion Battery (sold separately). Insert the battery into the saw. To start the saw, you need to use the trigger switch with the lock - off feature. It requires two actions, so be careful not to accidentally turn it on. When cutting, hold the saw firmly with one hand. The ergonomic design makes it comfortable to hold. You can adjust the blade speed according to the material you're cutting using the variable speed dial. The built - in L.E.D. light will help you see the work area clearly. For safety, always wear appropriate protective gear like goggles and gloves. When not in use, use the retractable tool hook to secure the saw. For maintenance, keep the saw clean. After use, wipe it down to remove any debris. Check the blade regularly for wear and tear. You can use the tool - less blade change lever to replace the blade quickly. If you're not using the saw for a long time, remove the battery to prevent over - discharging. Also, make sure to store the saw in a dry place to avoid rusting.
