A machine configured to free-wheel without operator
knowledge may cause death or serious injury and
property damage.
Collision hazard. Select a work site
that is firm and level.
Component damage hazard. If the
machine must be towed, do not
exceed 2 mph / 3.2 km/h.

between the wheels at the non-steer end of the
machine.
3 Lift the wheels off the ground and place blocks
under the drive chassis for support.
