8. PRECAUTIONS FOR MAINTENANCE

8.3 TIRES

HANDLING TIRES
If a tire or a rim is handled wrongly, the tire may burst or may be broken and the rim may be broken
and scattered, and that can cause serious injury and death.
To maintain safety, always observe the following items.
‡ Since maintenance, disassembly, repair and assembly of the tires and rims require special
equipment and technology, be sure to ask them for a tire repair shop.
‡ Use only the specified tires and inflate them to the specified pressure.
Suitable inflation pressure © See "24.2.15 SELECTION AND INSPECTION OF TIRES".
‡ When inflating a tire, check that any person will not enter the working area and use an air chuck
which has a clip and which can be fixed to the air valve.
While inflating the tire, check the inflation pressure occasionally so that it will not rise too high.
‡ Abnormal drop of inflation pressure and abnormal fitting of the rim indicate a trouble in the trouble
or rim. In such cases, be sure to ask a tire repair shop for repair.
‡ If the rim is not fitted normally, it may be broken and scattered while the tire is inflated.
Accordingly, place a guard around the tire and do not work in front of the rim but work on the
tread side of the tire.
‡ Do not adjust the inflation pressure of the tires just after high-speed travel or heavy-load work.
‡ Do not heat or weld a rim to which the tire is installed. Do not make a fire near the tire.
PRECAUTIONS FOR STORAGE OF TIRES
‡ As a basic rule, store the tires in a warehouse which unauthor-
ized persons cannot enter. If you must store the tires outside,
always erect a fence around the tires and put up a "No Entry"
sign.
‡ Stand the tire on level ground, and block it securely so that it
will not roll or fall over even if an unauthorized person touch
it. If the tire is placed on its side, it will be flattened and
deteriorated.
‡ If the tire should fall over, get out of the way quickly. Tires for
construction equipment are extremely heavy, so trying to hold
the tire may lead to serious injury.
