2.5 Precautions with tires
Handling tires
See also "Handling the tires (3-157)".
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.
z
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.
z Inflate tyres up to the defined pressure. If the tyre pressure is
too low, the tyres may heat up and burst. If the tyre pressure
is too high, there is also danger that the tyre may burst.
z If a tyre heats up considerably, inflammable gases are pro-
duced. A burning tyre may burst very easily, thus spreading
fire over a large area.
z Check the tyre pressure when the tyres are still cold. Do not
let off pressure, when the pressure in a warm tyre has
increased.
z Do not light a fire and do not carry out welding near the tyre.
z Keep the working area free of pointed or sharp objects that
may damage the tyre.
z Avoid any overload.
z The values for tyre pressure and permitted speed given in
this manual correspond to the manufacturers’ values. See
also "Handling the tires (3-157)".
z For details, please refer to your KOMATSU distributor or the
tyre manufacturer.
Precautions when storing tires
Tires for construction equipment are extremely heavy, so they
may cause serious personal injury.
z Basically, tyres must be stored in a protected room that can-
not be accessed by unauthorised persons.
z Place the tyres on an even surface and incline them 60° to
70° against a solid stopper. Secure the tyres with wheel
chocks so that they cannot roll away, tip over, or slip.
z If, however, a tyre tips over despite this safety measure, do
not try to stop it, but get out of the way as quickly as possi-
ble, since tyres for construction machines are very heavy
and may cause serious injuries.
