OPERATION
PRECAUTIONS WHEN DRIVING MACHINE
When the machine travels at high speed for a long distance, the tires become extremely hot. This causes early
wear of the tires, so it should be avoided as much as possible. If the machine must be driven for a long distance,
take the following precautions.
q Follow the regulations related to this machine, and drive carefully.
q Before driving the machine, carry out the checks before starting.
q The most suitable tire pressure, travel speed, or tire type differ according to the condition of the travel surface.
Contact your Komatsu distributor or tire dealer for information.
q The following is a guide to suitable tire pressures and speeds when traveling on a paved surface with standard
tires. (20.5-25-12PR)
Tire pressure
Front wheel: 0.32 MPa (3.3 kgf/cm2, 46.9 PSI)
Rear wheel: 0.27 MPa (2.8 kgf/cm2, 39.8 PSI)
Speed:14 km/h (8.7 MPH)
q Check the tire pressure before starting, when the tire is cool.

and coolant levels.
