Hi [MENTION=6976]silentheart[/MENTION] and @LazyBuddy , 1) any trick to get the weight bar perfectly leveled? I believe the 1 and a half inch thing mentioned in the manual is for tennis racket; that's too much error for badminton racket that has lower tension to begin with. 2) do you guys follow the manual to clean the jaws for every 6 rackets? 3) the stringing jobs I did on M140 yield consistently lower tension compared with local stringing shop's work. Do you guys experience the same thing? Thank you in advance.
