Joystick Controls
General Description
Fig. 6-2: Joystick
(Ref. Fig. 6-2) The joysticks control hydraulic flow to the associated
cylinders.
Control is proportional: The more joystick movement, the greater the
action. The speed of cylinder action is also affected by engine/hydraulic
pump speed. Action is quicker at higher engine speeds.
Joysticks can be moved in any direction and are not limited to front/back,
left/right movement. Moving a joystick in a diagonal direction will cause a
combination of actions.
A switch is located on the top of the front joystick, under a protective
rubber cap. Pressing this switch down with your thumb activates the
auxiliary function (models 644B, 844C, and 1044C only).
Note: Releasing the switch while moving the joystick left or right changes the
function of the joystick back to transfer carriage control.
