Boom Joystick
The boom joystick (1) controls the boom and attachment tilt functions.
Boom Functions
• Move the joystick back to lift boom; move joystick forward to lower boom; move
joystick right to extend boom; move joystick left to retract boom.
• Speed of boom functions depends upon 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 and retract
boom simultaneously.
Attachment Function
Tilt control is actuated by the switch (2).
• Depress left side of switch to tilt up; depress the right side of switch to tilt down.
• Use rotary switch (3) to regulate speed of the tilt. Rotate knob counter-clockwise
to increase speed; rotate knob clockwise to decrease speed.
WARNING
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.
