CANBUS SYSTEM SETUP
Before the engine is started from the crane for the first time,
the CANbus system needs to be initialized. Interface to the
CANbus system is through a laptop. To access the CANbus
system connector, remove the access panel on the
passenger side of the crane control console and plug the
cable into the CANbus system connector (Figure 9-26).
NOTE: The software and cable can only be purchased by
t e c h n i c i a n s t h a t h a v e a t t e n d e d t h e N e w
Technology training course.
Refer to the NBT30H-2 RCL specification for
detailed instructions to program or troubleshoot
using the RCL software.
• Turn the crane ignition switch to the ON position. Do not
try and start the engine.
• PTO must be engaged.
• Boot up the laptop and launch the CANbus system
software.
• Navigate to the engine configuration menu following the
on-screen instructions to:
- Select make of truck engine.
- Set the fuel level source address.
- Calibrate throttle pedals.
INITIAL CRANE RUN IN PROCEDURE
1. Place the crane in an area that allows for full operation of
all its functions.
NOTE: Make sure the hydraulic tank is full and the butterfly
valve in the suction line is on.
2. Engage the PTO, start the truck from the crane cab.
3. Program the RCL as outlined in the RCL manual.
4. Run the truck engine at idle and activate the crane
power switch.
5. Operate all crane functions and outriggers slowly at
least six (6) times to purge cylinders of air. Check that
the movement of the outriggers, boom, and hoist
correspond with direction indicated on the control levers.
Refer to the appropriate sections in this manual to
correct any problems.
NOTE: Add oil to reservoir as required to keep air out of
the system.
6. Adjust the throttle for the engine RPM and PTO ratio to
get proper pump shaft speed.
7. After all cylinders have been cycled, stow the crane and
place the outriggers in the up position. The oil level
should be visible near the top of the sight gage.
8. Lift and stability test must now be performed on the unit.
Hoist and crane tests need to be conducted to insure
proper performance.
9. After the stability test is complete, check the T-box and
frame mounting bolts for proper torque.
10. Measure the overall height of the crane and truck. Post
the overall height measurement inside the truck cab to
inform the driver of the overall height.
RCL CALIBRATION
After the crane has been installed and all electrical and
hydraulic connections are completed, calibrate the RCL.
Calibrate the RCL as described in the RCL manual titled
Calibration/Service Manual.
STABILITY TEST
The purpose of the stability test is to verify that the rated load
can be lifted with an 85% tipping factor. With an 85% tipping
factor, the crane can lift a rated load and be at 85% of the
tipping condition or less.
A stability test must be performed on each completed unit to
determine the 85% tipping factor. Proceed as follows:

DANGER
The loads used for stability tests put the crane at the
tipping point. Keep the hook load close to the ground.
Control of the boom position is critical. Do not allow the
test loads to swing out past the rated radius. If the crane
starts to overturn and the boom angle is too low the crane
may tip over.
