Bucket Auto Leveler

WARNING:
 Pay attention to safety to avoid personal injury and/
or death when adjusting the bucket auto leveler.
 Stop the engine. Lower the loader front on the
ground to release oil pressure.
 Apply the parking brake to prevent the machine
from moving unexpectedly. Wedge the wheels with
blocks. Keep bystanders away from the vicinity of
the machine.
The bucket auto leveler automatically stops the bucket
movement at the preset digging angle. (When the machine
is shipped from the factory, the bucket positioner is preset so
that the bucket is stopped with the bucket bottom parallel
with the road surface.)
For example, after discharging material into a truck or a
hopper, when control lever (4) is placed to detent position
(G), the lever is held in that position. Then, when the bucket
is returned to the preset angle position, the bucket is
automatically stopped and the lever is returned to hold (N).
The bucket auto leveler is preset so that when the bucket
bottom becomes parallel with the road surface, the bucket
is stopped. Nevertheless, when required to tilt the bucket
forward or backward more than level position, adjust the
bucket auto leveler by moving the mounting position of the
proximity switch.
