7-3 Bucket Dumping
Never perform high dumping on soft ground, an uneven surface or a
slope since it is dangerous. It would be extremely dangerous if the ma-
chine becomes unbalanced.
1) Raising of Bucket (High Dumping)

Stop the machine with the steering wheel directed straight forward.
Make sure that the front wheels are also directed straight forward. If the front
wheels are not directed straight forward, the machine will become unbalanced,
which is extremely dangerous.
2
Stop the rotation of the brushes.
3
Set the parking brake switch to the
"ON" position, and then raise the
brushes.
4
Shift the bucket up/down lever to-
ward
