Checklist B Procedures
B-3
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.
Bodily injury hazard. An
over-inflated tire can explode
and could cause death or serious
injury.
Tip-over hazard. Do not use
temporary flat tire repair
products.
Note: The tires on some machines 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.
4 Check the pressure in each air-filled tire.
