I am fairly new to track saws and have what is probably a dumb question about my T75. I was going to try a plunge cut and I have notice when the blade is in the up position at rest it sticks out about a 1/4 inch below the base. In other words when trying to plunge the blade is already hitting the wood so when I start the saw it really jumps off the track. Is it supposed to be like this and if so how do I actually start a plunge cut using the guide rails. Thanks for the help
