If the machine must be driven for a long distance, take the following precautions.
• Observe the regulations related to this machine, and drive carefully to assure safety.
• 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. Consult your Komatsu distributor or tire dealer.
• The following shows the appropriate tire pressure and travel speed when the machine is equipped with
standard tires and runs on the paved surface.
Front tire inflation pressure: 525 kPa {5.35 kg/cm
2
}
Rear tire inflation pressure: 525 kPa {5.35 kg/cm
2
}
Travel speed: 10 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.
However, when stopping the machine in extremely cold district, do not stop the engine abruptly to prevent
the radiator coolant temperature from rising sharply. Cool the radiator coolant down gradually before stop-
ping the engine.
• Always travel with the bucket empty.
• Never travel with calcium chloride or dry ballast in the tires.
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) Top face of indicator
Top face (A) of the indicator is in parallel with the cutting edge.
(B) Side face of indicator
Side face (B) of the indicator is at a right angle to the cutting
edge.
RECOMMENDED APPLICATIONS
In addition to the following, it is possible to further increase the range of applications by using various attach-
ments.
DIGGING WORK
WARNING
• Never perform digging or scooping operation with the machine articulated. There is a danger that
the machine may tip over.
• If the ECSS switch is turned on during travel or with the work equipment raised, the work equipment
starts moving.
• If the machine is operated with the ECSS switch at ON position, the work equipment may start mov-
ing at the moment when the ECSS is actuated.
NOTICE
If the tires slip, the tire life will be reduced, so operate the machine avoiding tire slippage.
LOAD STOCK PILES AND BLASTED ROCKS
When loading stock piles or blasted rocks, the machine is driven forward as shown below to scoop them. In this
case, pay attention to the following points in order to prevent cuts on the tires caused by tire slipping.
