ASSEMBLY
CAUTION: Handle banding
material with caution. Use heavy
leather gloves. Banding is sharp!
CAUTION: Use jack stands under
tractor whenever elevated off the
tires.
CAUTION: Avoid injury! Explosive
separation of tire and rim parts is
possible when they are serviced
incorrectly:
Do not attempt to mount a
tire without the proper
equipment and experience to
perform the job.
Do not inflate the tires above
the recommended pressure.
Do not weld or heat a wheel
and tire assembly. Heat can
cause an increase in air
pressure resulting in an
explosion. Welding can
structurally weaken or
deform the wheel.
Do not stand in front or over
the tire assembly when
inflating. Use a clip-on chuck
and extension hose long
enough to allow you to stand
to one side.
