Using this DeWalt oscillating tool is easy. First, if you need to change the blade or attachment, use the Quick - Change™ system. You don't need any wrenches, just make the switch quickly. When starting your work, turn on the tool using the trigger. You can lock it on or off for continuous or intermittent use. For better accuracy, especially in dark areas, turn on the bright LED to illuminate your work surface. You can adjust the speed according to your task with the variable speed trigger.
When using the tool, make sure to hold it firmly. Since the battery is not included, use a compatible 12V battery. Don't over - exert the tool beyond its capacity.
For maintenance, after each use, clean the tool with a dry cloth to remove dust and debris. Check the blades and attachments regularly for wear and tear. If they are damaged, replace them promptly. Store the tool in a dry and cool place to extend its lifespan.
