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. Apply park brake.
3. Place transmission control lever in neutral.
4. Start engine and allow a warming period.
5. While warming the engine, set up the Rated Capacity Limiter configuration.
6. Stow boom over front.
7. Pull hoist line snug.
8. Retract outriggers.
9. Step on the brake pedal.
10. Release park brake lever.
11. Shift transmission to desired gear.
12. Place forward/reverse lever in desired position.
13. Release brake and press on accelerator pedal.
14. Slow down when making turns.
15. Set park brake and lower outriggers or chock wheels to park.
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. Apply park brake.
3. Place transmission control lever in neutral.
4. Start engine and allow a warming period at low RPM.
5. While warming the engine, set up the Rated Capacity Limiter configuration.
6. Move accelerator pedal to medium to full speed.
7. Set all outriggers fully down on firm, level surface. Use timber or steel plate cribbing
under outrigger shoes as needed on soft or uneven surfaces. Outriggers should remain
set during all crane operations except for pick and carry.
8. Meter the controls when beginning or ending 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.
9. You may use the throttle control switch to set the engine speed to 1200 or 1800 RPM
when the park brake is on. Return to idle by releasing park brake momentarily.
10. Release accelerator during idle time and shut off engine, if practical.
NORMAL GAUGE READINGS
Level Indicator: Do not operate crane if it is not level.
Fuel: Do not allow fuel tank to become empty. The engine will be difficult to restart and may
require "bleeding" of diesel injectors. Keep fuel tank full when idle to prevent condensation
in tank.
