Check the Free-wheel
Configuration
Proper use of the free-wheel configuration is
essential to safe machine operation. The
free-wheel configuration is used primarily for
towing. 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.
1 Chock the steer wheels to prevent the machine
from rolling.
2 Center a lifting jack of ample capacity
(15000 lbs/6804 kg) under the drive chassis
between the non-steering wheels.
3 Lift the wheels off the ground and then place
jack stands under the drive chassis for support.
4 Disengage the torque hubs by turning over the
torque hub disconnect caps on each
torque hub.
5 Manually rotate each non-steering wheel.
Result: Each non-steering wheel should rotate
with minimum effort.
6 Re-engage the torque hubs by turning over
the hub disconnect caps. Carefully remove
the jack stands, lower the machine and
remove the jack.
Collision hazard. Failure to
re-engage the torque hubs may
cause death or serious injury and
property damage.
