I am about to embark on a new attachment for my TB 135. I am gonna purchase a Mini Disc Mulcher; however, it has to be operated in the Hammer Mode. I saw the Hammer Mode switch on the front of my machine but have never touched it. I would imagine that if this mode doesn't work correctly, it would mess up my next investment. My TB 135 has a thumb attachment, what would happen if I switch to Hammer Mode with the thumb attachment and operate? Would the thumb only operate in one direction? I just want to make sure that I don't do something wrong and blow a seal or something.
