Using the DeWalt DWHT38125S tape measure is easy. Pull out the blade to the length you need. Use the integrated finger brake to stop the blade at the right position. The fractional blade graphics will help you read the measurements quickly. When you're done, press the brake to retract the blade slowly. For safety, don't let the blade snap back too fast as it could cause injury. Keep the tape measure clean. Wipe it with a dry cloth after use. Store it in a dry place to prevent the blade from rusting. This will also help maintain the durability of the blade coating and keep your tape measure in good condition for a long time.
