The maximum speed setting of a joystick and
toggle switch controls the maximum speed of a
machine function. 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 can be changed to compensate
for hydraulic pump wear and to maintain peak
performance from the machine.
There are two types of max speed settings.
High flow functions : Secondary up / down and
extend / retract.
