when they are serviced incorrectly:
• Do not attempt to mount a tire without the
proper equipment and experience to
perform the job.

assembly. Heat can cause an increase in air
pressure resulting in an explosion. Welding
can structurally weaken or deform the

assembly when inflating. Use a clip-on
chuck and extension hose long enough to
allow you to stand to one side.
