Wheel Maintenance

• Mishandling of a tire and rim parts can cause serious injury
or death.
• Inspect tires and wheels daily. Do not operate with low
pressure, cuts, bubbles, damaged rims, or missing lug
bolts and nuts.
• When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side and
not in front of or over the tire assembly. Use a safety cage
if available.
• Do not attempt to inflate or mount a tire unless you have
the proper equipment and experience to perform the
job. Have it done by your authorized dealer or a qualified
repair service.
• Always maintain the correct tire pressure. DO NOT inflate
tire above the recommended pressure.
• Explosions of air inflated tires have resulted from heat-
induced gas combustion inside the tires. Explosions
can be caused by heat that is generated by welding, by
heating rim components, by external fire, or by excessive
use of brakes. Explosions differ from punctures or tire
bursts because the destructive force is extremely large.
This could result in tire explosion which could propel
projectiles in excess of 500 m (1640 ft) from the machine.
Both the force of the explosion and the flying debris can
cause property damage, personal injury, or death. If tire
overheating is suspected or noticed, do not approach the
tire within any area included in the shaded area (15 m in
radius) in the illustration and restrict access underneath
the truck, until the tire has cooled down sufficiently.
• Store tires safely.
• Store tires in the place where tires are not exposed to the
direct sunlight, rain, water and oil. Avoid near external
heat source or electric sparks hazard.
• Stand tire on level ground, and block it securely so that it
cannot roll or fall over.
• Store the tires in a warehouse in which unauthorized
persons cannot enter. If the tires are stored outside,
always erect a fence around the tires and put up "No
Entry" and other warning signs that even young children
can understand.
