Inspect the Tires and Wheels
Maintaining the tires and wheels in good condition
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.
An over-inflated tire can
explode and may cause death
or serious injury.
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 every lug nut for proper torque.
4 Check the pressure in each air-filled tire.

Confirm 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 the torque hub disconnect caps to be
sure they are in the engaged position.
2 On 4WD models, be sure the free-wheel valve
on the drive pump is closed (clockwise).
