PRECAUTIONS WITH TIRES

HANDLING TIRES

If tires or rims are handled mistakenly, there is danger that the tire
may explode or be damaged, or that the rim may fly off and cause
serious injury or death.
To maintain safety, always do as follows.
Maintenance, disassembly, repair, and assembly of the tires
and rims requires special equipment and special technology, so
always ask your Komatsu distributor to carry out these
operations.
Use only the specified tires and inflate them to the specified
pressure.
Suitable inflation
INSPECTION OF TIRES (PAGE 4-34)".
When pumping up the tires, check that no other person is
standing near the tire, and install an air chuck with a clip that can
be secured to the air valve.
To prevent the tire inflation pressure from becoming too high,
measure the pressure from time to time with an air gauge while
pumping up the tire.
If the tire pressure goes down abnormally or the rim parts do not
fit the tire, there is a problem with the tire or rim parts. Always
contact your Komatsu distributor for repairs.
If the rim parts are not fitted properly when the tire is being pumped up, there is danger that the rim parts may fly
off, so set up a protective fence around the tire, and do not stand directly in front of the rim. Stand beside the tread
when pumping up the tire.
Do not adjust the tire inflation pressure immediately after traveling at high speed or carrying out operations under
heavy load.
Never carry out welding or light a fire near the tire.

PRECAUTIONS WHEN STORING TIRE

Tires for construction equipment are extremely heavy, so trying to
hold the tire may lead to serious injury.
As a basic rule, store the tires in a warehouse which
unauthorized persons cannot enter.
If the tires must be stored outside, always erect a fence and put
up "No Entry" signs.
Stand the tire on level ground, and block it securely so that it
cannot roll or fall over if any person should touch it.
Do not lay the tire on its side. This will deform the tire and cause
it to deteriorate.
If the tire should fall over, do not attempt to stop it. Get out of the
way quickly.
