SEQUENCE OF OPERATION
DRIVING THE VEHICLE
The following procedure is recommended for driving the vehicle:
1. Perform the daily inspection and test. (See Page 3-4)
2. Start engine and allow a warming period.
3. While warming the engine, set up the Rated Capacity Limiter (RCL) configuration.
4. Stow boom over front.
5. Pull hoist line snug.
6. Stow the outriggers.
7. Step on the brake pedal.
8. Release park brake switch by selecting the desired range, direction (forward or reverse),
and the desired gear to operate the machine in.
9. Release brake pedal and press on accelerator pedal.
10. Slow down when making turns.
11. When parking the vehicle, set park brake and lower outriggers , or chock wheels.
W A R N I N G
Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and
odorless. Breathing engine exhaust fumes can cause death or serious illness. Do not
run the engine in enclosed areas without adequate ventilation.
OPERATING THE CRANE
The following procedure is recommended for placing the crane in operation:
1. Perform daily inspection and test. (See Page 3-4)
2. Drive crane to lifting location. Take the time to survey the location for obstacles, solid
footing, and check if crane is spotted within the lifting radius for the load being lifted.
3. Start engine and allow a warming period at low RPM (if not already running).
4. Apply park brake, which also places the transmission in neutral.
5. Set all outriggers fully down on firm, level surface. Use appropriate cribbing under
outrigger shoes as needed on soft ground. Outriggers should remain set during all
crane operations except for pick and carry.
6. Set up the Rated Capacity Limiter (RCL) configuration for the boom and outrigger
conditions.
7. Enable the ARM button on the 15-button panel to activate the joysticks. Meter the
controls when beginning or ending any movement. This prevents suddenly starting or
stopping, which causes unsafe load swinging and shock loads on the equipment. The
control should be slightly actuated to begin movement and then slowly increased to
desired speed. Metering can be improved by coordinating with the accelerator pedal.
8. You may use the throttle control switch to set the engine speed to one of the preset RPM
options when the park brake is on. Return to idle by cycling through set points to return
to low idle, or by using the decrement speed buttons.
9. Release accelerator when crane is not in use and shut off engine, if practical.
NOTICE
Any change in outrigger position , when in the working mode , will cause the RCL to
revert back to set-up mode. The system senses a configuration has changed even if
temporarily.
