PRECAUTIONS FOR OPERATION
• When leaving the machine, set lock lever (1) to LOCK po-
sition (L), then stop the engine.
• Always close the operator's cab door, and use the key to
lock all the equipment in order to prevent any unauthorized
person from operating the machine. Always remove the
key, take it with you, and keep it in the specified place.
• If it is necessary to park the machine on a slope, always
observe the following.
• Set the work equipment on the downhill side and dig it
into the ground.
• In addition, block the tracks from movement.
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.
PRECAUTIONS WHEN LOADING AND UNLOADING
If handling is improper when loading or unloading the machine, it is dangerous that the machine may tip over or
fall. It requires particular attention. Always observe the following.
• Perform loading and unloading on a firm, level ground only. Avoid road edge or place near the cliff.
• Never use the work equipment to load or unload the machine. There is danger that the machine may fall or
tip over.
• Always use ramps of adequate strength. Be sure that the
ramps are wide, long, and thick enough to provide a safe
loading slope. Take suitable steps to prevent the ramps
from moving out of position or coming off.
(1) Chocks
(2) Ramp
(3) Center of ramp
(4) Angle of ramp: Max. 15 °
• Be sure the ramp surface and the platform of trailer are
clean and free of grease, oil, ice, water and other loose
materials. If any, remove them. Remove dirt around the un-
dercarriage of the machine. On a rainy day, in particular, be extremely careful since the ramp surface is
slippery.
• Always turn the auto-deceleration switch OFF (cancel). If the machine is operated with the auto-decelera-
tion system ON (activated), there is danger that the engine speed will suddenly rise, the machine will sud-
denly move off, or the machine travel speed will become faster.
