Removal and Installation of Tire

d
WARNING: Wheel with tire 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.
In case jacking up the machine is required, be sure to
observe the following points.
 Select dry, solid and flat ground for a work site.
 Work in a group of more than two personnel. One
person shall mainly engage in practicing the work
and others shall 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 than
necessary.
 When the front (rear) wheels are raised off the
ground, wedge wheel stoppers under the rear (front)
wheels.
 After the machine is raised off ground, be sure to
block the machine using rigid supports. Never leave
the machine to be supported only by jacks.
 The rear wheels oscillate. Insert wooden blocks
between the axle and the frame 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 finally removed.
 Wheel bolt tightening torque: 890 N·m (89 kgf·m,
656 lbf·ft)

WARNING: When a tire wheel must be removed, ask a
professional person to do so.
Allow only an authorized person to inflate a tire after
the tire was installed onto the wheel.
Sufficiently remove rust from the wheel. Severe rust
may cause the wheel to crack, possibly causing the
machine and/or personal accidents.
