Using the DeWalt DWA5842 floor scraper is a breeze. First, make sure the 4 bolts and 4 nuts are properly tightened to secure the blade. Then, simply position the extra - wide stainless - steel blade against the material you want to remove, like tiles or glued - down carpets, and start scraping. As you work, if you notice the blade isn't cutting as well, don't worry. You can easily replace it to keep the tool in top shape. When it comes to maintenance, after each use, clean the blade with a dry cloth to remove any debris. Store the tool in a dry place to prevent rusting. Also, check the bolts and nuts regularly to ensure they are tight. This way, your DeWalt DWA5842 will serve you well for a long time.
