OPERATION UNDER USUAL CONDITIONS - CONTINUED
TRAVELING - CONTINUED
When loaded and traveling across a hillside, reduce speed significantly BEFORE turning uphill. Failure
to do so may cause machine to roll over, resulting in injury or death to personnel.
When loaded and an uphill turn is required, turn uphill ONLY by making a wide turn at a very slow speed.
10. In the event of a brake failure, drop scraper bowl to aid in stopping machine.
11. If machine becomes stuck when traveling with load, perform the following to break free:
Raise bowl to maximum height.
Move machine forward or back, while at the same time steering in quick succession, first sharp left, then sharp
right, etc. This technique is called "duck walking".
The following instructions are intended to provide basic procedures on dumping and spreading load.
Additional 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,
Whenever possible, dump downhill.
If there is a supervisor at fill 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. Down-
If entering a fill 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; or
4-6 in. (5-15 cm) to dump load as quickly as possible when merely stockpiling material.
At start of dump area, engage elevator in reverse.
Move ejector forward and open floor of bowl.
Finish dumping load. Slowly raise bowl in order to leave dump area as smooth as possible. Raise bowl high enough
to clear obstructions.
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 floor of bowl.
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.
