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
Turn the auto-decelerator switch OFF (auto-deceleration
function released).
q
Run the engine at low speed and travel slowly.
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.
Refer to “TRANSPORTATION (3-169)“.
SHIPPING THE MACHINE
When shipping the machine on a trailer, do as follows.
q
The weight, transportation height, and overall length of the machine differ according to the work equipment, so
be sure to confirm the dimensions.
q
When passing over bridges or structures on private land, check first that the structure is strong enough to sup-
port the weight of the machine. When traveling on public roads, check first with the relevant authorities and fol-
low their instructions.
