LOAD-AND-CARRY OPERATION
k k
WARNING
• When carrying a load, lower the bucket to lower the center of gravity of the machine and drive.
• If the ECSS switch is turned ON during travel or with the work equipment raised, the machine starts
moving instantly. Take care.
• If the machine is operated with the ECSS switch ON, the work equipment may starts moving at the
moment when the ECSS is actuated. Take care.
NOTICE
When traveling continuously in load-and-carry operation,
choose the appropriate tires to match the operating condi-
tions, or choose the operating conditions to match the
tires. If this is not done, the tires will be damaged.
Consult your Komatsu distributor or tire dealer.
The load and carry method for wheel loaders consists of a cy-
cle of scooping → hauling → loading (into a hopper, glory hole
etc.).
Maintain the travel road constantly in good condition.
LOADING WORK
Select an efficient loading method which minimizes the number of turns and travel distance according to the job
site.

WARNING
• Maintain the ground of job site level. Do not perform sudden steering or braking while the boom is
being raised with the bucket loaded. This is dangerous.
• Never thrust the work equipment into the target material (soil or crushed rock) when the machine is
traveling at high speed. This is dangerous.
• If the ECSS switch is turned on during travel or with the work equipment raised, the machine starts
moving instantly. Take care.
• If the machine is operated with the ECSS switch ON, the work equipment may start moving at the
moment when the ECSS is actuated. Take care.
• When the boom is below the level position, if the bucket TILT operation is performed further from
the tilt end, the boom may rise. If the bucket DUMP operation is performed just after this, the boom
may lower a little. Take care.
NOTICE
• If the tires slip, their service lives will be shortened. Take care that the tires do not slip during opera-
tion.
• Avoid excessive shaking of the bucket.
