Proper maintenance can prolong the life of
unit. The following charts show the
recommended service schedule. More
frequent service may be required due to
extreme working conditions (heavy loads,
high ambient temperatures, dusty conditions,
or airborne debris).
See the maintenance instructions in the
engine manual for additional information.
WARNING: Safety interlock system failure
and improper operation of unit can result in
death or serious injury. Test this system each
time the unit is operated. If this system does
not function as described, do not operate
until repairs are made. see Safety Interlock
System on page 16.
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.
