PRECAUTIONS RELATED TO SEMI-AUTO MODE
• Be sure to perform the warm-up operation before starting the work. If the work equipment is operated with-
out sufficient warming-up operation of the machine, response of the work equipment to movement of the
control lever will be slow. There is a danger that the work equipment may not respond as the operator in-
tends, or the semi-auto limited digging mode may not operate normally.
Warm up the engine adequately especially in the cold weather. Start the work after checking that the work
equipment moves smoothly.
• Improper use of the semi-auto limited digging mode can lead to an unexpected move of the work equip-
ment, or the semi-auto limited digging mode may not operate normally.
Refer to the content of “SEMI-AUTO MODE”, and get a full understanding of it before start using the ma-
chine.
• Perform calibration before start using the semi-auto limited digging mode. There is a danger that the work
equipment may not respond as the operator intends if it is operated with semi-auto limited digging mode
without calibration.
• Check the bucket configuration before start using the semi-auto limited digging mode. There is a danger
that the work equipment may not respond as the operator intends if it is operated with semi-auto limited
digging mode whose bucket configuration is different from the bucket actually installed.
PRECAUTIONS FOR TRANSPORTATION
When the machine is transported on a trailer, serious personal injury or death may result because of the acci-
dent during transportation. Always observe the following.
• Always check the machine dimensions carefully. Depending on the work equipment and optional devices
installed, the machine weight, transportation height, and overall length differ.
• Check beforehand that all bridges and other structures on the transportation route are strong enough to
withstand the combined weight of the transporter and the machine being transported.
• This machine may need to be divided into components for transportation depending on the regulation.
When transporting the machine, consult your Komatsu distributor.
