2 . Install the driving crank on each shaft.
3 . Set a link between the right and left driving
cranks to connect them.
4 . Install the knee lifter lever on the left driving
crank.
5 . The operating force can be lightened by

the left driving crank as shown in the dotted
line of the figure. However, in this case the
operation amount of the knee lifter lever is
increased.
