OPERATION UNDER USUAL CONDITIONS - CONTINUED
The following instructions are intended to provide basic procedures on dumping and spreading load. Addi-
tional information on dumping/spreading techniques can be found in WP 0006 00, Advanced Operation and
Operator Tips. BEFORE dumping/spreading load, read the instructions in WP 0006 00, as well as these pro-
Whenever possible, dump downhill.
If there is a supervisor at dump area, dump load where directed to do so (with the required lift height).
When you arrive at dump (fill) area, release accelerator pedal to reduce engine RPM. Apply service brakes. Downshift
If entering a dump area with soft underfoot, engage differential lock.
Dump material at highest practical travel speed--1st or 2nd gear operation is average for optimum performance.
Lower bowl to required spread (lift) height:
2-4 in. (5-10 cm) to provide material lift for subsequent compaction
4-6 in. (5-15 cm) to dump load as quickly as possible when merely stockpiling material
Open apron at start of dump area.
Move ejector forward.
Finish dumping load. Slowly raise bowl in order to leave dump area as smooth as possible. Raise bowl high enough to
Always return ejector to rear of bowl after dumping load. This reduces the chance of hydraulic cylinder
damage due to bouncing when traveling at higher speeds.
10. Return ejector to rear of bowl and close apron.
11. Return to cut area at highest practical travel speed for job site conditions.
12. On subsequent dumping/spreading passes, consider straddle dumping:
Leave a gap between 1st and 2nd dumping passes that is less than distance between tires.
On the third trip, unload between 1st and 2nd passes, at a spread depth GREATER THAN previous passes; this will
leave a new ridge.
Repeat until desired depth of spread is achieved.
