Section 2 - Pre-Operation and Controls
Optional Controls
The joystick (1) controls the boom, attachment and outrigger functions.
Boom Functions
• Move the joystick back to lift boom; move joystick forward to lower boom.
• Boom extend/retract is controlled by the rocker switch (2). Push the rocker switch
up to extend boom; push the rocker switch down to retract boom.
• The speed of boom functions depends upon the amount of joystick travel in
corresponding direction. Increasing engine speed will also increase function
speed.
• For two simultaneous boom functions, move the joystick between quadrants. For
example; moving the joystick forward and to the left will lower boom and tilt
attachment back (up) simultaneously.
TIP OVER/CRUSH HAZARD. Rapid, jerky operation of controls will cause rapid,
jerky movement of the load. Such movements could cause the load to shift or fall
or could cause the machine to tip over. Failure to comply could result in death or
serious injury.
