Service Manual
Checklist B Procedures
B-8
Inspect the Tires, Wheels and
Lug Nut Torque
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Maintaining the tires and wheels, including proper
wheel fastener torque, is essential to safe
operation and good performance. Tire and/or
wheel failure could result in a machine tip-over.
Component damage may also result if problems
are not discovered and repaired in a timely fashion.
Note: The tires on this machine are foam filled and
do not need air added to them.
1 Check all tire treads and sidewalls for cuts,
cracks, punctures and unusual wear.
2 Check each wheel for damage, bends and
cracked welds.
3 Check each lug nut for proper torque. Refer to
Specifications, Machine Specifications.

B-9
Check the Drive Hub Oil Level
and Fastener Torque
Genie specifications require that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Failure to maintain proper drive hub oil levels may
cause the machine to perform poorly and continued
use may cause component damage.
Drive hubs:
1 Drive the machine to rotate the hub until the
plugs are located one at the side and the other
at the other side.
1 drive hub plugs
2 Remove both plugs and check the oil level.
Result: The oil level should be even with the
bottom of the plug holes.
3 If necessary, add oil until the oil level is even
with the bottom of the plug holes. Refer to
Specifications, Fluid Capacity Specifications.
4 Install the plug in the drive hub.
5 Check the torque of the drive hub mounting
fasteners. Refer to Specifications, Machine
Torque Specifications.
6 Repeat this procedure for each drive hub.
