Leveling operation
NOTE
!
Always operate the machine in reverse when carrying out
leveling operations.
If it is necessary to carry out leveling operations when travel-
ing forward, do not set the bucket dumping angle to more
than 20 degrees.
!
Turn the E.C.S.S. switch (option) OFF when carrying out lev-
eling operations.
1. Scoop soil into the bucket. Move the machine backward
while spreading soil from the bucket little by little.
2. Go over the spread soil with the bucket teeth touching the
ground and level the ground by back-dragging.
3. Scoop some more soil into the bucket, put the lift arm control
lever in FLOAT position, level the bucket at ground level,
and smooth the ground by moving backward.
Pushing operation
CAUTION
Never set the bucket to the DUMP position when carrying out
pushing operation.
When carrying out pushing operations, set the bottom of the
bucket parallel to the ground surface.
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 travel damper is actu-
ated, 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 (3-148)".
