WARNING: When operating a machine equipped with
ride control and the lift arm control lever in the float
position, when performing works as soil scooping,
land grading, or snow removal, be sure to turn the
ride control switch OFF. Failure to do so may allow
the ride control system to operate so that the front
attachment may automatically move up and down.
IMPORTANT: Perform grading work while moving the
machine in reverse. If grading work is performed by
moving the machine forward, severe loads are applied
to the front attachment, possibly creating cracks or
damage to the front attachment.
1. After filling the bucket, dump the bucket gradually to
spread soil while moving the machine in reverse.
2. Lower the bucket edge onto the ground. Grade and
level the ground surface while driving the machine in
reverse with the bucket edge dragging.
3. After filling the bucket with a load such as soil, position
the bucket level with the ground surface. Finish the
ground surface utilizing the bucket weight.
At this time, move the machine in reverse with the lift
arm held in the FLOAT position.
