FUNCTION SPEED/TORQUE ADJUSTMENT
The speed of each crane function (all drums, travel, swing)
and swing torque can be adjusted to suit operator needs.
Adjustment
To adjust the desired function’s speed or swing torque,
proceed as follows:
1. Stop operating the desired function and park it.
2. Access diagnostic screens ( Figure 3-16 ):
a. Turn limit bypass key clockwise and scroll up at
least one screen (with selector next to display
screen).
b. Once step 2a is performed, release key and scroll
up or down through diagnostic screens until speed
and torque screen appears.
3. Press BOTTOM of CONFIRM/SELECT switch until
cursor (
* ) appears next to desired function.
4. Scroll up or down to change speed or torque of selected
function to desired percentage between 25% and 100%.
5. Repeat steps 1, 3 and 4 for other functions, as desired.
6. Press BOTTOM of CONFIRM/SELECT switch until
cursor (
* ) disappears.
7. Adjustment is complete. The selected speeds and
torque will remain in computer memory, even after
engine is stopped.
8. If desired, turn off diagnostic screens:
a. Turn limit bypass key clockwise.
b. Once step 8a is performed, scroll down at least one
screen and release key.
Stopping engine will also turn off diagnostic screens.

controllers.
• Controller programming information —These screens
are for factory use only, and are not shown in this folio.
• Hydraulic system calibration information — Check
includes pressure sender calibration, control calibration,
pump pressure test, and charge pressure test.
• Speed adjustment screen — Allows for setting each
