Welcome!
Be sure to exercise the camera through it's entire speed range a few times if it has been setting unused for an extended period. These mechanical cameras need to be used on a regular basis or they tend to stiffen-up and won't give optimal results.
Try 5 exposures per shutter speed several times while watching a movie or something.
Might have to do it by yourself, or someone might throw something at you for the noise! Ask me how I know...
It's a great camera! Enjoy.
