WARNING:
 Take extra care to prevent injury and/or death
when adjusting the lift arm auto leveler (kickout).
 Apply the parking brake to prevent the machine
from moving unexpectedly. Chock the wheels with
blocks. Keep bystanders away from the vicinity of
the machine.
IMPORTANT:
 When the lift arm auto leveler (kickout) function is
activated with the bucket loaded, the bucket may
stop at the set position.
 Height setting of lowering direction can not be
done when the lift arm is above the horizontal
position of the lift arms. Also, height setting of
raising direction can not be done when the lift arm
is below the horizontal position of the lift arms.
The lift arm auto leveler is a device that automatically
stops the lift arm at the preset position while lowering or
raising the lift arm. It is convenient to change the setting
of stop position by using this function when the machine
is constantly used in a specific way, such as when loading
trucks that are equipped with side boards of the same
height.
Refer to page 1-38 to adjust the stop position.
