SEQUENCE OF OPERATION
DRIVING THE VEHICLE
The following procedure is recommended for driving the vehicle to the job site:
1. Perform the daily inspection and test. (See Page 3-4)
2. Apply park brake.
3. Leave hydrostatic transmission switch in neutral.
4. Start engine and allow a warming period. (If equipped with Safety Shutdown System,
depress reset button while starting, and for a few seconds after.)
5. Set up the Rated Capacity Limiter configuration while warming the engine.
6. Stow boom over front.
7. Pull hoist line snug.
8. Retract outriggers.
9. Step on the brake pedal.
10. Turn parking brake off.
11. Place transmission switch in FORWARD or REVERSE.
12. Release brake and press on accelerator pedal gradually until movement starts. There is
a built-in delay after pedal movement, before the vehicle moves.
13. Slow down when making turns.
14. Release accelerator pedal gradually to slow down and stop.
15. Step on brake pedal for abrupt stop.
16. Set park brake and outriggers or wheel chocks to park.
WARNING
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.
To start the engine, the transmission switch must be in NEUTRAL. The switch should always
be kept in neutral except for travel. Step on the brake before switching to FORWARD or
REVERSE. Then release the brake and push the accelerator pedal to begin travel. Motion
begins at about 1500 RPM engine speed. (Idle speed is about 700 RPM & maximum speed is
about 2500 RPM for the gas engine, and 2600 RPM for diesel.)
The hydrostatic transmission will normally stop the crane on a grade -- but some oil will slip
through the wheel drive motors and allow the crane to creep. ALWAYS apply parking brake
when operating the crane, or leaving the crane unattended. Also, extend the outriggers if
possible. Remember the hydrostatic transmission is NOT a parking brake.
On level surfaces, the brake pedal is not required for normal stopping. On slopes, the
operator may have to coordinate the brake and the accelerator to make smooth starts and
stops. Emergency stops can be made more quickly by stepping on the brake pedal. This
combines hydrostatic braking with the action of the disc brakes. Operating both accelerator
and brake pedal with the right foot is preferred. Using the left foot on the brake pedal while
simultaneously using the right foot on the accelerator will allow the engine to over-speed.
W A R N I N G
Abrupt braking from stepping on the foot brake at travel speeds may cause loss of
control of a load on the hook or on the deck. The operator should anticipate stops, and
slowly let up on the accelerator pedal to make smooth stops.
