Problem

  • Even when the starting pedal is stepped on fully, the machine does not run with high speed; also cannot decrease the speed
Reasons

  • The installed nut of the stop motion lever catch is loose
  • Belt too loose
  • Defective position of the belt shifter
  • Adjusting bolt of starting lever loose

Solution

  •  Adjust the belt length
  •  Adjust the forward and backward positions of the belt 4.
  •  Adjust the bolt so that when the pedal is stepped on, the catch will interlock for high speed
