operator will be permitted to cycle power and restart the
engine once with approximately 2 minutes of run time.
After the 2 minute run time is complete or if the engine is
shut down by the operator prior to the completion of the
2 minute run time, it cannot be restarted until fuel is
added to the tank.
• Engine Restart - When the engine shuts down, the operator will be permitted to cycle power and restart the
engine for approximately 2 minutes of run time. After the
2 minutes of run time is complete, the operator may cycle
power and restart the engine for an additional 2 minutes
of run time. The operator can repeat this process until
there is no more fuel available.
• Engine Stop - The engine will shut down. No restarts will
be permitted until fuel is added to the tank.

4.4TRAVELING (DRIVING)
SECTION 4 - MACHINE OPERATION
See Figure 4-3., Grades and Sideslopes
DO NOT DRIVE WITH BOOM EXTENDED OR ABOVE HORIZONTAL EXCEPT ON A SMOOTH,
FIRM AND LEVEL SURFACE.
DO NOT DRIVE WITH HOODS RAISED OR UNLATCHED.
TO AVOID LOSS OF TRAVEL CONTROL OR UPSET ON GRADES AND SIDESLOPES, DO NOT
DRIVE MACHINE ON GRADES OR SIDESLOPES EXCEEDING THOSE SPECIFIED ON MACHINE
INFORMATION PLACARD ON THE LEFT SIDE OF THE FRAME.
TRAVEL GRADES WITH DRIVE SPEED/TORQUE SELECT SWITCH IN THE FORWARD POSITION. USE EXTREME CAUTION WHEN DRIVING IN REVERSE AND AT ALL TIMES WHEN
DRIVING WITH PLATFORM ELEVATED AND ESPECIALLY WHEN DRIVING WITH ANY PART
OF MACHINE WITHIN 6 FEET (2 M) OF AN OBSTRUCTION. DO NOT USE DRIVE TO MANEU
VER PLATFORM CLOSE TO AN OBSTRUCTION...USE ONE OF THE BOOM FUNCTIONS.
BEFORE DRIVING, LOCATE THE BLACK/WHITE ORIENTATION ARROWS ON BOTH THE
CHASSIS AND THE PLATFORM CONTROLS. MOVE THE DRIVE CONTROLS IN A DIRECTION
MATCHING THE DIRECTIONAL ARROWS.
Traveling is limited by two factors:
1. Gradeability, which is the percent of grade of the incline the
machine can climb.
-
2. Sideslope, which is the angle of the slope the machine can
be driven across.
When the boom is raised or extended, the machine should not
be operated on grades or sideslopes that are greater than that
detected by the tilt alarm. The tilt alarm will sound to alert the
operator when the machine is on an unsafe slope. The
machines high drive function will also be cut back to low drive.
