Using the Bosch MS1234 miter saw length stop kit is easy. First, decide which side of your Bosch miter saw you want to mount the kit on. Then, use the included mounting hardware to securely attach it. Once it's installed, you can set the length for your repeated cuts. Just slide the stop to the desired position and lock it in place. When you're done using the kit, simply store it on the tool itself. For maintenance, keep the kit clean. Wipe it down after each use to remove sawdust and debris. Check the mounting hardware regularly to make sure it's tight. If you notice any damage, replace the parts as soon as possible. And always follow the safety instructions provided by Bosch when using your miter saw and this kit.
