Adjustment of Bucket Auto Leveler
d
WARNING: CRUSH HAZARD
 Be careful to avoid injury and/or death when
adjusting the bucket auto leveler.
 Stop the engine. Lower the loader arm and bucket
to the ground to release oil pressure.
 Apply the parking brake to prevent unexpected
movement of the machine. Chock wheels with
blocks. Keep bystanders away from the vicinity of
the machine.
The bucket auto leveler automatically stops the bucket
movement when level. (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 bucket control lever (5) 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 neutral
(N).
The bucket auto leveler is preset so that when the bucket
bottom becomes parallel with the road surface, bucket
movement is stopped. Nevertheless, when required to tilt
the bucket forward or backward beyond the level position,
adjust the bucket auto leveler by moving the mounting
position of the proximity switch (4), relative to rod (3).
