It sure couldn't hurt to have the unit looked over, but if it's working there is nothing more the shop will do for you. The set-down weight of the arm is not set by counterweight. There is no adjustment that is done for a turntable like this. The only user-serviceable items are the needle and the idler wheel, so you can expect to replace them every once in a while and that's about it.
