WARNING: When operating the machine with the
front attachment control lever in the float position
when performing such 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: Be sure to perform grading work while
driving the machine in reverse. If grading work is
performed by driving the machine forward, severe
loads are applied to the front attachment, possibly
causing cracks or damage to the front attachment.
1. After filling soil into the bucket, dump the bucket
gradually to disperse soil while driving the machine in
reverse.
2. Lower the bucket teeth tips onto the ground. Grade and
level the ground surface while driving the machine in
reverse with the bucket teeth tips 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, drive the machine in reverse with the lift
arm held in the FLOAT position.
