Hi fellas, I bought this hardness tester at a local school auction. I can't find much information on it and was hoping someone could lead me in the direction of an owner's manual. It is a Louis Small Service Diamond Model 8BLP.
The problem I have is, the loading handle turns only a few degrees then encounters very strong spring resistance. Something out of adjustment?
Thanks for any help,Oscer.
