Eachwheel is equipped with a wheel drive
pin (A, Figures 3-2 and 3-3) that secures
the wheel to the wheel shaft (B). The
wheels can be positioned in either a
WHEELDRIVEora FREEWHEEL mode.
WARNING: Neverallow
either of the wheels to be in the
FREEWHEEL position when the
engine is running. Always put
both wheels in the WHEEL
DRIVEposition beforestarting
