OPERATION
LEVELING OPERATIONS
NOTICE
Always operate the machine in reverse when carrying out leveling
operations.
If it is necessary to carry out leveling operations when traveling forward,
do not set the bucket-dump angle to more than 20 degrees.
Turn the E.C.S.S. switch (if equipped) OFF when carrying out leveling
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
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
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 actuated, 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 (PAGE
3-156)".
