Load and carry operations

WARNING
When carrying a load, lower the bucket to lower the center of
gravity when traveling.
When the machine is traveling or the work equipment is
raised, the moment that the E.C.S.S. switch is turned ON,
the work equipment will move.
If operations are carried out with the E.C.S.S. switch left at
the ON position, the moment that the E.C.S.S switch is
turned ON, the work equipment will move.
The load and carry method for wheel loaders consists of a cycle
of scooping -> hauling ->loading (into a hopper, truck, etc.)
Always keep the travel path properly maintained.
When using the load and carry method, see "Precautions for
using load and carry method (3-158)".

Loading operations

Select the method of operation which will give the minimum
amount of turning and travel in order to provide the most efficient
method for the jobsite.
WARNING
Always keep the jobsite level. When the lift arm is raised with
the bucket loaded, it is dangerous to operate the steering
suddenly or apply the brakes suddenly. Do not carry out
such operations.
It is dangerous to thrust the bucket into the material to be
loaded (borrow pit, crushed rock, etc.) at high speed. Do not
carry out such digging operations.
When traveling or when the work equipment is raised, if the
E.C.S.S. swith is turned ON, the work equipment will move
at that instant, so operate carefully.
If operations are carried out with the E.C.S.S. switch ON, the
work equipment may move at the instant the E.C.S.S. is
actuated, so operate carefully.
NOTE
If the tires slip, the tire life will be reduced, so do not allow
the tires to slip during operation.
Avoid excessive bucket shaking.
