be prepared to react to an emergency
situation:
• Return steering levers to neutral

Check 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. Use a clipon chuck and extension
hose long enough to allow
you to stand to one side.
See "SPECIFICATIONS" on page 34.
