  • Page 11: Assembly Steps

    ASSEMBLY STEPS Assembly steps In the steps for assembly we will use the terms "RH part" and "LH part". The distinction is conventionally made looking at the machine from the rear. For the purpose of simplification, we will illustrate machine assembly for one side only; since the machine is symmetrical, each operation must be done on both sides.
  • Page 12 ASSEMBLY STEPS For correct assembly, the RH support 3 and the LH support 2 must lean in slightly towards the center of the machine. After assembly, they must have the measurements given (minimum width). At this point, before moving on to next step, keep in mind that the assembly is unstable and therefore it is recommended that extreme caution be used.
