For the crane with deadman switches on the joysticks:
You must push in the deadman switch (on left or right joystick) for the joystick
commands to operate the crane.

For the crane with a deadman switch on the seat:
You must sit on the seat until the indicator illuminates for the joystick
commands to operate the crane.
F. The boom angle indicator and the angle detector attach to the side of the main boom.
Refer to Figure 7-16. The operator can see the angle indicator from the cab of the
crane. The angle detector is an electronic device that sends the boom angle data to
the LMI (Load Moment Indicator). The boom angle shows on the display screen.

WARNING
Do all derricking movements smoothly. You can cause damage to the crane if you
move the load up or down with quick stops.
You can cause a dangerous condition if you try to lift a heavy load with the boom at
a low angle. Make sure that you follow the Load Ratings.
