Section 3 • Repair Procedures
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.
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 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.
PLATFORM CONTROLS
8 Momentarily activate the drive enable toggle
switch in the right direction until
THRESHOLD
is shown on the display.
9 Momentarily activate the steer rocker switch
in the right direction until
RAMP UP TIME
is
shown on the display.
10 Momentarily activate the drive enable toggle
switch in the right direction to enter
RAMP UP
TIME
calibration mode.
11 Press down on the foot switch and momentarily
activate the function to be corrected.
Result: The display will show the function,
direction and the actual stored value.
12 Press down on the foot switch, start a timer
and activate the same function in the same
direction. Note how long it takes the function
to reach maximum speed. This is the ramp up
time.
13 Compare the function ramp up time with
the table on the next page and determine
whether the ramp up time needs to increase or
decrease.
14 To adjust the ramp up time setting, release the
foot switch. Momentarily move the steer rocker
switch in the right direction to increase or
momentarily in the left direction to decrease.
Each time the steer rocker switch is momentarily
pressed, the time will change in 0.1 second
increments.
Changing the ramp up time setting in one direction
will also change the opposite direction.
