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 personal 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 specified tires and inflate them to the specified
pressure.
Suitable inflation pressure : see HANDLING TIRES (PAGE
3-114).
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.
Always release all pressure from a single tire or from both tires of a dual assembly prior to removing any rim
components.
Before removing the tire from the machine for repairs, remove the valve partially to release the air from the tire,
then remove the tire.
