position. (Select the required step)

speed changing lever is at the step 1, the speed will be based on the reference point of
the step 1 (as mark d in the fig. 2). On the contrary, when the two step speed changing
lever is at the step 2, the speed will be based on the reference point of the step 2 (as
mark e in the fig. 2).
f. Switch the Hi-lo speed changing lever to the required position.
