is warm from operation. Water can seep into bearings and damage
them.
See SPECIFICATIONS on page 28 for correct tire pressure.
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.

you to stand to one side.
