Middle Joystick
The middle joystick (3) controls boom and second auxiliary hydraulic (if equipped)
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.
• 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 and retract boom
simultaneously.
Second Auxiliary Hydraulic Function (if equipped)
• For attachments that require a second hydraulic supply for operation, press
button (2) to activate auxiliary hydraulics control. The button must be held down
while moving the joystick left or right. See Section 5 - Attachments for approved
attachments and control instructions.
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.
