into the customer’s equipment.
 (Component on fixed side)

gear.

Confirm that the design of the prepared component on the fixed side conforms to the size and
quantity of the mounting bolts for the base flange indicated in the catalog and in the separately
provided “Outer dimensions” drawings and specification sheet.

Use the positioning pin or positioning plate when aligning the component on the fixed side with the
reduction gear.

(Component on rotation side)
Prepare the installation component on the rotation side to be attached to the output shaft of the reduction
gear.

Confirm that the design of the prepared component on the rotation side conforms to the size and
