àMounting the Brandnew Workload Unit

1. Assemble the brandnew workload unit so that it will engage

with the workload unit mounting metal base of the frame (Fig.

1). Be careful that the copper disk plate will not touch the

frame.

2. Tighten the crank nut by using a cotterless gear crank

removing/ fastening tool and a wrench (Figs. 2 and 3).

Tightening torque should be 350kg cm to 400kg·cm, and

tighten the nut until the end of the crank shaft can level with the

end surface of the nut. Then, put the crank cap with a coin or

the like. (Fig. 4)

3.	Assemble the chain. Chain should first be set on the free
	wheel before setting it to the upper part of the large gear.
	Then, a forward rotation of the crank will enable the complete
	setting on the large gear. (Fig. 5)
4.	Set the derailleur spring to the pawl of the derailleur to give
	tension to the chain. (Fig. 6)
5.	Adjust the position of the workload unit so that the tension of
	the chain at the workload unit can be adequate. Move the
	workload unit back and forth so that the longer edge of the
	derailleur fixing metal base can be positioned at a right angle
	to the derailleur spring. (Fig. 6)
6.	Tighten the workload unit fixing screw (two screws on either
	right and left sides). (Fig. 7) The tightening torque is 90kg·cm
	to 120kg·cm.
7.	Assemble the workload reinforcing metal base in between the
	bolts at the workload side and the frame side, and tighten the
	bolts with nuts. (Fig. 8)

*In case the nut is screwed in at the position where the workload-unit-side workload unit metal base is supposed to be mounted, remove the nut.

*The tightening torque at the workload unit side should be 90kg·cm to 120kg·cm, and the nut at the frame side should be provisionally tightened.
