Needle bearing 708 rolls on slide guide and needle bearing 808 rolls under slide guide plate as illustrated
in Fig. 6B. Because of this functional reason, needle baring 708 is assembled to the eccentric rotation axis
as illustrated in Fig. 6C.

Turn the rod gripping its flat portion with wrench, until needle bearing 708 touches on slide guide and
needle bearing 808 touches on slide guide plate. However, these needle bearings have to slightly touch
on them to keep smooth sliding. And then, fix the rod with hex socket hd. bolt M5 x 6.
Thus, the rod can be assembled correctly as illustrated in Fig. 6A and 6B.
