I wouldn't say it's normal to basically work as a technician (unless you're training, in which case that's not unheard of and a generally good thing), but I could be wrong since I haven't worked at too many different places. Whether it's normal or not is less important than if you're ok with it, which is something only you can decide. As a follow up though, have you been explicitly told not to do anything beyond hands on work, or do you have the opportunity to take a step back and do some more big picture stuff? Ideally, at some point you should be starting to look at doing things like reducing maintenance related downtime, better predicting machine failures (and therefore preventing surprise breakdowns), reducing the time or resources needed for a frequent maintenance task, etc. The hands on work you're doing and any relationships you make with the technicians will be very helpful with this, both in helping you identify the problems to focus your attention on as well as being able to ask technicians for help with any aspect of solving the problem(s). Having said that, if you feel like you're being pigeonholed into a career path that you don't want, or your company keeps you as a glorified technician and not an actual maintenance engineer, learn all you can while also finding another job.
