Removal and Installation of Tire
d
WARNING: A wheel and tire assembly is a very
heavy part so that removal and installation of a tire
is hazardous and difficult work. In addition, a crane
to lift a tire is required when removing or installing
the tire to the wheel. Consult your nearest authorized
dealer or a professional tire sales shop for tire removal
and installation work. When jacking up the machine,
observe the following points.
 Select dry, solid and flat ground for a work site.
 Work in a group of more than two persons. One person
to mainly do the work and others to work as assistants
and/or ensure safety.
 Do not use the bucket to raise the front wheels.
 Do not raise the machine off the ground higher
necessary.
 When one axle is raised off the ground, block the tires at
the axle that is still in contact with the ground.
 After the machine is raised off ground, be sure to block
the machine using rigid supports. If wooden blocks
are used for "cribbing" support, use only hard wood
blocks. Never use soft wood for support. Never leave the
machine to be supported only by jacks.
 The rear wheels oscillate. Insert wooden blocks between
the axle and the chassis to stop oscillation.
 When removing the wheel bolts, lift the wheel with
a crane so that the wheel bolt remaining at the top
position is removed lost.
