Using the Makita DF012DSE is a breeze. First, choose the right bit for your task and insert it into the 1/4' hex chuck. You can quickly change bits thanks to this convenient feature. Decide whether you want to use the tool in straight or pistol grip position based on your comfort and the nature of the job. Next, select the appropriate speed. Use 200 RPM for low - torque tasks and 650 RPM for high - torque ones. Then, set the clutch according to the required fastening torque. There are 21 clutch settings to choose from, with a range from 32 to 50 in.lbs. When you start working, the auto - stop clutch will shut off the tool when it disengages, preventing over - driving. If you're working in low - light conditions, turn on the built - in L.E.D. work light using the separate switch. Keep an eye on the battery. When the L.E.D. light blinks, it's time to recharge the battery using the provided 7.2V - 12V max Lithium - Ion charger. Only use genuine Makita batteries and chargers to ensure proper performance. After each use, make sure to clean the tool. You can use a soft cloth to wipe it down. Store the tool in the provided tool case when not in use. This helps protect it from damage. Remember, the tool, battery, and charger come with a 3 - year limited warranty, so if you have any issues, you're covered.
