Using your DeWalt DCS356C1 oscillating multi - tool is easy. First, charge the 20V MAX* Lithium Ion Battery using the DCB107 Charger. Once it's charged, insert the battery into the tool. Decide which blade you need for your job - the wood cutting blade for wood or the wood/metal blade for both wood and metal. Use the Quick - Change™ system to attach the blade. You can adjust the speed with the 3 - speed selector according to the task. For more precise speed control, use the DUAL - GRIP™ variable - speed trigger. When working in a dark area, turn on the LED light. As for maintenance, after each use, wipe down the tool to remove any debris. Keep the battery charged but don't over - charge it. Store the tool in the kit bag provided to protect it from dust and damage. Also, check the blades regularly for wear and replace them when necessary.
