PROCEDURES
D-2
Check the Free-wheel
Configuration
Note: Genie specifications require that this
procedure be performed every 1000 hours or
annually, whichever comes first.
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.
Component damage hazard. If the
machine must be towed, do not
exceed 2 mph / 3.2 km/h.
1 Chock the steer wheels to prevent the machine
from rolling.
2 Center a lifting jack of ample capacity
(15,000 lbs / 7000 kg) under the drive chassis
between the non-steer wheels.
3 Lift the wheels off the ground and then place
blocks under the drive chassis for support.
4 Disengage the drive hubs by turning over the
drive hub disconnect caps on each
non-steer wheel hub.
5 Manually rotate each non-steer wheel.
Result: Each non-steer wheel should rotate with
minimum effort.
6 Engage the drive hubs by turning over
the drive hub disconnect caps.
7 Carefully remove the blocks, lower the machine
and remove the jack.
Collision hazard. Failure to engage
the drive hubs could result in
death or serious injury and
property damage.
