Maximum Speed Setting
The maximum speed of a joystick controlled
machine function can be modified from the ground
controls display. Whenever a hydraulic cylinder,
drive motor or hydraulic pump is replaced, the
maximum speed setting should be adjusted to
maintain optimum performance. The maximum
speed settings on the joystick can be changed to
compensate for hydraulic pump wear to maintain
peak performance from the machine.
Note: Perform this procedure with the boom in the
stowed position.
