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 3-39
):
a. Turn limit bypass key clockwise and scroll up at
least one screen (D5, page 3-22

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

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 DIAGNOSTICS
General
The Cummins QSX15 Engine has two types of fault codes:
• Engine electronic fuel system fault codes
• Engine protection system fault codes
All fault codes are either active or inactive. Active engine
faults can be viewed on the crane’s digital display either with
the engine running or with the engine off (run/stop/run switch
in RUN position). Inactive faults can only be read with
electronic service tool supplied by the engine manufacturer.
The engine diagnostic lights are mounted on the front
console in the operator’s cab as shown in Figure 3-40
.
RED STOP LIGHT
When on, the red stop light indicates the need to stop
engine as soon as safely possible and correct the fault.
YELLOW WARNING LIGHT
When on, the yellow warning light indicates that engine can
be run, but the fault should be corrected as soon as possible.
WHITE MAINTAIN LIGHT
When on, the white maintain light indicates that engine
maintenance is required. See engine manufacturer’s manual
for maintenance instructions.

corrected.
