Using the DeWalt DWS535B circular saw is easy. First, make sure it's plugged in. Then, adjust the bevel angle as needed using the bevel detents at 22.5 and 45 degrees for common angles or set it up to 53 degrees for advanced jobs. If you want to use the rip guide, attach the DWS5100 dual port rip guide (sold separately) to the dual rip ports. When you're ready to cut, hold the saw firmly and pull the trigger. The powerful 15 Amp motor will start the blade spinning at 4,800 rpm. Once you're done cutting, release the trigger and the electric brake will stop the blade quickly. As for maintenance, keep the saw clean after each use. Check the cord regularly for any damage because of the Toughcord cord protection. If you need to change the blade, use the top - accessible spindle lock to make the process easier. And always store the saw in a dry place to prevent rusting.
