Grease the Axle Wheel Bearings -
CE Models
Axle specifications require that this
procedure be performed every 6
months or 10,000 km, whichever
comes first.
Maintaining the axle wheel bearings is essential to
safe operation and good machine performance.
Towing the machine with loose or worn wheel
bearings may cause an unsafe towing condition
and continued use may result in component or
property damage. Regular steam cleaning and
pressure washing of the machine may require that
this procedure be performed more often.
1 Loosen the wheel lug bolts. Do not remove
them.
2 At the ground controls, extend the outriggers
until the axle is off the ground and the machine
is level.
3 Remove the lug bolts and remove the tire and
wheel assembly from the machine.
4 Remove, wash and inspect the axle wheel
bearings and spacer ring.
5 Pack both bearings with clean, fresh grease.
6 Install the bearings and spacer ring onto the
axle and reassemble the axle.
7 Tighten the castle nut until the wheel runs with a
little bite.

to Section 2, Specifications.
