ADJUSTING WORK EQUIPMENT POSTURE
WARNING
Stop the machine on flat ground and put blocks in front and behind the
wheels.
Apply the parking brake.
Secure the front and rear frames with the frame lock bar.
Always attach the warning tag to the work equipment control lever.
Do not go under the work equipment when the arm is raised.
The boom kickout makes it possible to set the bucket so that it
automatically stops at the desired lifting height (lift arm higher than
horizontal) and the bucket positioner makes it possible to set the
bucket so that it automatically stops at the desired digging angle.
The setting can be adjusted to match the working conditions.
For machines equipped with an EPC work equipment lever (if
equipped), refer to the section of "METHOD OF REMOTE
POSITIONER (PAGE 6-49)" in the chapter, ATTACHMENT AND
OPTION, in this manual.
ADJUSTING BOOM KICKOUT

Raise the bucket to the desired position, return the lift arm
control lever to the HOLD position, set the work equipment lock
lever to the LOCK position, then stop the engine.
