ASSEMBLY
WARNING: AVOID INJURY.
Read and understand entire
Safety section before proceeding.
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.
WARNING: FAILURE OF
INTERLOCK together with
improper operation can result in
severe personal injury.
WARNING: FAILURE OF
CONTROLS could result in death
or serious injury.
