Precautions with tires 0.
Handling tires 0.
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 technol-
ogy, so always ask your Komatsu distributor to carry out
these operations.
Always use the tires specified by Komatsu and maintain the
specified inflation pressure.
Suitable tire inflation pressure: see “Handling the tires on
page 3-96“.
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 tires 0.
Tires for construction equipment are extremely heavy, so they
may cause serious personal injury.
As a basic rule, store the tires in a warehouse which unau-
thorized 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.
