some pokies are murder to work on

Feeling like shit tonight, hands are giving me hell and i seem to be overly irritable, starting to do well at work again. The 2IC said I did ok servicing the machines he had seen so far... The only issues I have is the Konami Tasman series machines, I can't seem to get into service the buttons as well as I can others i can't get the front rows out.. ah well on monday I need to see if I can ask the boss if there is an easier way to do the button changes
