2. Wheel Base Width Adjustment
Adjusting the wheelbase width allows the rider the
option to move the wheels closer or further away from
the hips. This gives the proper wheel spacing to maxi-
mize pushing efficiency.
Adjusting the wheelbase width: (Fig. 10)
a. Loosen the nuts, and reposition the axle sleeve	A
