Using this DeWalt tool tote is easy. First, open the tote and start organizing your tools in the 36 pockets and loops. Put the frequently used tools in the easily accessible pockets. When you're on a jobsite, just grab the tote and go. It can withstand rough handling, but try not to drop it from a great height. For maintenance, if it gets dirty, you can use a damp cloth to wipe the dirt - repellant tarpaulin. Make sure the IP54 water - resistant compartment is dry before you store any sensitive tools. Also, check the zippers regularly to ensure they're working smoothly. If there are any issues, contact DeWalt's customer service.
