PRECAUTIONS FOR TRAVELING
A long distance travel at high speed can heat the tires extremely and cause premature damage on them. Avoid
it as long as possible.
If the machine must be driven for a long distance, take the following precautions.
• Follow the regulations related to this machine, and drive carefully.
• Before driving the machine, perform the checks before starting.
• The most suitable tire pressure and travel speed differ according to the tire type and condition of the travel
surface. Contact your Komatsu distributor or tire dealer.
• The following shows the appropriate tire pressure and travel speed when the machine is equipped with
standard tires (23.5R25 ☆ ) and runs on the paved surface.
The tire pressure of both front and rear wheels is 400 kPa {4.0 kg/cm
2
}.
Travel speed14 km/h
• Check the tire inflation pressure before driving, when the tires are cool.
• Stop the machine for 30 minutes after the travel of 1 hour, and check the tires and each part for any abnor-
mality. Check the oil level and coolant level as well.
When stopping the machine in extremely cold areas, do as follows.
Do not stop the engine abruptly to prevent the radiator coolant temperature from rising sharply. Cool the
radiator coolant down gradually before stopping the engine.
• Always travel with the bucket empty.
• Never travel with calcium chloride or dry ballast in the tires.
PAY ATTENTION TO DEF LEVEL
Before working on a slope or traveling on a rough ground, check DEF tank and add sufficient amount of DEF as
necessary. If the remaining DEF level becomes low, sudden drop of its level or abnormality in urea SCR system
may be detected. If DEF level caution lamp or DEF system caution lamp lights up in red, move the machine to a
level place immediately and add DEF.
METHOD FOR CHECKING BUCKET ANGLE
The indicator in the top right side corner of the bucket allows
check of the bucket angle during operation.
(A): In parallel with cutting edge
(B): At 90° to cutting edge
RECOMMENDED APPLICATIONS
