4.8 Service procedure When required Maintenance Selection and inspection of tires If a tire or a rim is handled wrongly, the tire may burst or may be damaged and the rim may be broken and scattered, and that can cause serious injury or death. Since maintenance, disassembly, repair and assembly of the tires and rims require special equipment and skill, be sure to ask a tire repair shop to carry out the work. Do not heat or weld the rim to which the tire is installed. Do not make a fire near the tire. GK032084 Selection of tires Select the tires according to the conditions of use and the weight of the attachments on the machine.
Use only speci- fied tires and inflate them to the specified pressure. Select the tires according to the conditions of use and the weight of the attachments of the machine. Since the travel speed indicated on the speedometer varies with the tire size, consult your KOMATSU distributor when using optional tires. Check inflation pressure of tires When inflating a tire, check that no one will enter the work- ing area. 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 occa- sionally so that it will not rise too high. If the rim is not fitted normally, it may be broken and scat- tered while the tire is inflated.
To ensure safety, place a guard around the tire and do not work in front of the rim but work on the tread side of the tire. Abnormal drop of inflation pressure and abnormal fitting of the rim indicate trouble in the tire or rim. In this case, be sure to ask a tire repair shop to carry out repairs. Be sure to observe the specified inflation pressure. Do not adjust the inflation pressure of the tires just after high-speed travel or heavy-duty work.
