Check the Tires, Wheels
and Lug Nut Torque
Maintaining the tires and wheels in good
condition, 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 with the exception
of High Flotation tires.
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
Section 2, Specifications .

Confirm the Proper
Brake Configuration
Proper brake configuration is essential to safe
operation and good machine performance.
Hydrostatic brakes and hydraulically-released,
spring-applied individual wheel brakes can appear
to operate normally when they are actually not fully
operational.
1 Check each drive hub disconnect cap to be
sure it is in the engaged position.
2 Be sure the free-wheel valve on the drive pump
is closed (clockwise).
Note: The free-wheel valve is located on the drive
pump.
