Operation

Joystick Operation (Single Joystick Option)

The single joystick option is an assembly containing a single joystick (1) to control

boom functions, auxiliary hydraulics, attachment tilt and the PlaceAce™ transfer

carriage operation. The frame sway is controlled by a separate frame sway joystick

(2) which is located behind the single joystick assembly.

The joystick can be operated in two separate modes of operation: without button (3)

depressed “Boom Lift/Lower and Extend/Retract” (Default Mode) and with button (3)

depressed and held “Transfer Carriage Extend/Retract and Auxiliary Hydraulic Male

Pressurized/Female Pressurized” (Secondary Mode). The joystick also has a thumb

control (4), on the topside of the joystick, for attachment tilt control which operates in

either mode.

IMPORTANT! The button (3) must be held against the joystick handle during

operation of the Secondary Mode. Releasing the button (3) from the Secondary

Mode will immediately

change the joystick back to the Default Mode of operation.
