BUCKET DUMP ANGLE WHEN LEVELLING
Drive the machine in reverse when carrying out leveling opera-
tions.
If leveling operations are carried out with the machine traveling
forward, do not make angle (a) between the cutting edge of the
bucket and the ground surface facing down more than 8°. If
leveling operations are carried out when driving forward with
angle (a) between the cutting edge of the bucket and the
ground surface facing down more than 8°, the bucket cylinder
will be pushed by the pushing force of the machine. This will
cause the cylinder to retract and the bucket will face down at a
greater angle, so there is danger of the work equipment break-
ing.
LOADING BUCKET
Do not load the bucket or scoop up the load with the load on
the corner of the bucket or the load on one side of the bucket.
This will cause the machine to twist and will reduce the service
life of the work equipment and the frame.
When carrying out digging or scooping-up operations, thrust
the center of the bucket into the load.
