Using your DeWalt wheeled backpack is simple. First, open the zippers and start placing your tools in the appropriate pockets. Put your drill and batteries in the dedicated compartments. For your laptop and other electronics, use the separate laptop area. When you're on the move, you can either carry it as a backpack or use the wheels for easy transportation. As for maintenance, keep it clean by wiping off dirt and debris regularly. Make sure to close all zippers properly to protect the contents from water and dust. Avoid overloading the backpack to prevent damage to the fabric and wheels. If it gets wet, let it dry completely before storing it.
