Replace Tires
Tighten the nut to the proper torque to prevent the
tire from loosening. Use a torque wrench to
tighten the fastener, if you don't have a torque
wrench, use a socket wrench to tighten the
fastener and then immediately have a service
station or dealer to tighten the fastener to the
correct torque. Over-tightening will cause the
bolts to break or permanently deform the bolt
holes in the tires.
The correct steps to replace a tire are as follows:
1. Make sure the machine is in stowed position.
2. Press the main power switch and disconnect all
power sources (such as battery charger) connected
to the machine.
3. Use a wrench to loosen but do not remove the tire
retaining nut.
4. Use a jack with sufficient load capacity to lift the ma-
chine frame to the appropriate height so that the tire
assembly is off the ground.
5. Remove the tire retaining nuts and bolts alternately,
and then remove the tire.
6. Align the mounting hole of the new tire with the cor-
responding mounting hole in the frame.
7. After applying Loctite 272 threadlocking adhesive to
the bolts and nuts, install the bolt and nuts
sequentially.
8. Tighten all nuts by hand first to prevent loosening of
the bolts and nuts. Never apply lubricant to threads
or nuts.
9. Then tighten the nuts step by step in the order as
shown below. Please refer to the recommended tor-
que in the table below for tightening.
