Using the DeWalt DWE625 Plunge Router is quite straightforward. First, plug it into a power source. Then, select the appropriate collet (either 1/4 - inch or 1/2 - inch) for your router bit and use the single - wrench to secure it with the help of the spindle lock button. Adjust the speed using the variable speed dial according to your routing task. You can set it anywhere from 9,000 to 22,000 RPM. For depth adjustment, use the micro - fine depth stop adjuster and the 3 - stage adjustable turret for quick and accurate results. Hold the comfortable handles and use the built - in trigger to start and stop the router. You can even use the lock - on function for continuous operation. When you need to change the routing depth, just use the easily reachable plunge lock lever and release paddle. As for safety, always wear safety goggles and ear protection. Make sure the router is unplugged before changing bits. To keep it in good shape, clean the router regularly, especially around the motor and the base. After each use, wipe it down to remove dust and debris. If you're using the dust extraction feature with the DEWALT® Air Lock™ (sold separately), empty the dust collection container as needed. And don't forget to check the cord for any signs of damage periodically.
