Hi recently purchased the topaz tec 5, unfortunately there was no manual from the previous owner. The company was based in Brisbane, however I'm struggling to find any information. My club (Mount Gravatt) doesn't have any info in the library. A couple of members have older machines from the 80's but they don't have the prism alignment on the protractor. Would appreciate any info, documents on this machine. I know l have to get a single line when aligning, but l'm really finding this difficult on a consistent basis. Yes I'm very new and it may be a rookie error problem. Any assistance appreciated Cheers Nick
