2.5 Precautions With Tires

2.5.1 Handling tires

Explosive separation of a tire and/or rim parts

can cause serious injury or death.To ensure

safety, always do as follows.

●

When carrying out maintenance,

disassembly, repair, or assembly of the

tire or rim, special tools and procedures

must be used. Always ask your Komatsu

distributor to do the work.

●

Use only specified tires and inflate them

to the specified pressure.

●

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

Fig. 2.5-1

high, measure the pressure from time to

time with an air gauge while pumping up

the tire.

●

If the pressure goes down abnormally or

the rim parts go not fit the tire, there is a

problem with the tires 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
