Loading

C AU T I O N
Maneuver around large obstructions when loading scraper. Driving over large objects may
damage transmission case.
N OT E
The following instructions are intended to provide basic procedures on properly loading
scraper. Read these procedures BEFORE loading scraper.
Raise or lower cutting edge on scraper bowl to proper height before beginning loading
operations.
To provide maximum efficiency, a supervisor may be used to coordinate loading operation.
Refer to WP 0004 for the location and operation of controls.
1. Position machine near end of previous loading pass. Provide some overlap for a smooth cut area.
N OT E
Loading is most efficient when done on a level grade or a slight downhill grade. If cut area
is on a grade, load downhill whenever possible.
2. Load machine in direction of dump (fill) area, if possible. This reduces work cycle time by reducing travel time
and eliminating the need for turning loaded machine around.
3. Ensure ejector is moved to rear of bowl before beginning loading pass.
4. Open apron part way.
5. When arriving at cut, reduce travel speed by using service brakes.
C AU T I O N
Do NOT engage differential lock control while a wheel is spinning. Do NOT turn machine
with differential lock engaged. Turning machine with differential lock engaged will cause
excessive slip and wear to tires; torque wrap in transmission will also cause tractor to
"hop", and damage to differential or other machine equipment may result.
N OT E
Maintain high engine rpm (not to exceed 2,450 rpm) for fast hydraulic action. Maintain
proper gear to prevent tire slip in rocky or abrasive material.
6. As required, engage differential lock.
7. Select appropriate speed for material being loaded.
a. Use low speed for hard or coarse material.
b. Use high speed for soft material.
8. Maintain engine speed when cutting.
