PRECAUTIONS FOR OPERATION
SAFETY
2-30
TRANSPORTATION 2
When the machine is transported on a trailer, there is danger of serious personal injury or death during transporta-
tion. Always do as follows.
q
Always check the machine dimensions carefully. Depending on the work equipment installed, the machine
weight, transportation height, and overall length may differ.
q
Check beforehand that all bridges and other structures on the transportation route are strong enough to with-
stand the combined weight of the transporter and the machine being transported.
q
The machine can be divided into parts for transportation, so when transporting the machine, please contact
your Komatsu distributor to have the work carried out.
LOADING AND UNLOADING
When loading or unloading the machine, mistaken operation
may bring the hazard of the machine tipping over or falling, so
particular care is necessary. Always do as follows.
q
Perform loading and unloading on firm, level ground only.
Maintain a safe distance from the edge of the road or cliff.
q
Never use the work equipment to load or unload the
machine. There is danger that the machine may fall or tip
over.
q
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.
q
Be sure the ramp surface is clean and free of grease, oil,
ice and loose materials. Remove dirt from machine-tracks.
On a rainy day, in particular, be extremely careful since the
ramp surface is slippery.
q
For machines equipped with an auto-deceleration device,
always turn the auto-deceleration switch OFF. If the
machine is operated with the auto-deceleration system
ON, there is danger that the engine speed will suddenly
rise, the machine will suddenly move off, or the machine
travel speed will become faster.
q
Run the engine at low idling and drive the machine slowly at low speed.
q
When on the ramps, do not operate any lever except for the travel lever.
q
Never correct your steering on the ramps. If necessary, drive off the ramps, correct the direction, then enter
the ramps again.
q
The center of gravity of the machine will change suddenly at the joint between the ramps and the track or
trailer, and there is danger of the machine losing its balance. Travel slowly over this point.
q
When loading or unloading to an embankment or platform, make sure that it has suitable width, strength, and
grade.
q
When swinging the upper structure on the trailer, the trailer is unstable, so pull in the work equipment and
swing slowly.
q
For machines equipped with a cab, always lock the door after boarding the machine. If this is not done, the
door may suddenly open during transportation.
