PRECAUTIONS FOR OPERATION

TRANSPORTATION

When the machine is transported on a trailer, there is danger of serious personal injury or death during
transportation. Always do as follows.
Always check the machine dimensions carefully. Depending on the work equipment installed, the machine
weight, transportation height, and overall length may 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.
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.
Perform loading and unloading on firm, level ground only.
Maintain a safe distance from the edge of the road or 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.
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.
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.
Run the engine at low idling and drive the machine slowly at low speed.
When on the ramps, do not operate any lever except for the travel lever.
Never correct your steering on the ramps. If necessary, drive off the ramps, correct the direction, then enter the
ramps again.
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.
When loading or unloading to an embankment or platform, make sure that it has suitable width, strength, and
grade.
When swinging the upper structure on the trailer, the trailer is unstable, so pull in the work equipment and swing
slowly.
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.
Refer to "TRANSPORTATION (PAGE 3-175)".
