SERVICE PROCEDURE
SELECTION AND INSPECTION OF TIRES
WARNING
If a tire or a rim is handled improperly, 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 do the work.
Do not heat or weld the rim to which the tire is installed. Do not make a
fire near the tire.
SELECTION OF TIRES
WARNING
Select the tires according to the conditions of use and the weight of the attachments on the machine. Use only specified 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. Use the
following table.
Since the travel speed indicated on the speedometer varies with the tire size, consult your Komatsu distributor when
using optional tires.
