Check the Free-wheel
Configuration
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
(20,000 lbs / 10,000 kg) under the drive
chassis between the non-steer tires.
3 Lift the wheels off the ground and then place
jack stands under the drive chassis for
support.
