OPERATION
LOAD-AND-CARRY OPERATION
k k
• When carrying a load, lower the bucket to lower the
center of gravity of the machine and drive.
• If the ECSS switch is turned to ON position during
travel or with the work equipment raised, the machine
starts moving instantly. Take care.
• If the machine is operated while the ECSS switch stays
in ON position, the work equipment may start moving
at the moment when the ECSS is actuated. Take care.
The load and carry method for wheel loaders consists of a cycle of scooping → hauling → loading (into a hop-
per, glory hole etc.).
Maintain the travel road constantly in good condition.
When performing load-and-carry operation, see "PRECAUTIONS FOR LOAD-AND-CARRY OPERATION
(3-257)".
LOADING WORK
• Level the job site constantly. While the boom is being raised with the bucket loaded, sudden steer-
ing or braking is dangerous, so never do it.
• Never thrust the work equipment into the target material (soil or crushed rock) when the machine is
traveling at high speeds. This is dangerous.
• If the ECSS switch is turned to ON position during travel or with the work equipment raised, the ma-
chine starts moving. Take care.
• If the machine is operated while the ECSS switch stays in ON position, the work equipment may
start moving at the moment when the ECSS is actuated. Take care.
NOTICE
• If the tires slip, their service lives are shortened. Take care that the tires do not slip during opera-
tion.
• Avoid excessive shaking of the bucket.
Select an efficient loading method which minimizes the number of turns and travel distance according to the job
site.
