How to Adjust the Function Ramp
Up Time Setting
The ramp up time setting of a function controls the
time at which it takes for the function to reach
maximum output, when moved out of the neutral
position. The ramp up time of a function can be
changed to compensate for hydraulic pump wear to
maintain peak performance from the machine.
Note: Begin this procedure with the rotary speed
control at the platform turned fully in the clockwise
direction.
1 Turn the key switch to platform control.
2 Pull out the red Emergency Stop button to the
'ON' position at both the ground and platform
controls.
3 Do not press down on the foot switch.
4 Move and hold the drive enable toggle switch
in the right direction while holding the steer
rocker switch in the right direction.
5 When the display leaves SYSTEM READY
mode, release the drive enable toggle switch
and the steer rocker switch.
Result: The display will show FAULTS.
6 Momentarily activate the steer rocker switch in
the right direction until SETTINGS is shown on
the display.
7 Momentarily activate the drive enable toggle
switch in the right direction until VALVE AND
PUMP SETTINGS is shown on the display.
8 Momentarily activate the drive enable toggle
switch in the right direction until THRESHOLD
is shown on the display.

momentarily activate the function to be
corrected.

direction and milliamps.

direction.

the ramp up time needs to increase or
decrease.
