SCRAPER OPERATION CONTINUED
N OT E
Cut should be shallow enough for machine to move ahead at a constant speed. If cut is
too deep, engine will labor or lug down. Excessive tire slippage may occur.
Depth of cut can be gauged by observingdepth of penetration of side router bits.
9. Lower bowl to cutting depth that is efficient for loading material and start cut. Decrease cutting depth if engine
begins to labor or if tires slip.
10. Drive machine in a straight line during cut.
11. Regulate apron opening to prevent material from piling in front of cutting edge or falling out of bowl.
N OT E
Do NOT overload bowl. Stop cut when slight spillage of material is evident or when
directed to do so by supervisor.
12. When bowl is full, raise bowl slowly while you continue to drive forward in a straight line (this will result in a
smoother transition). Do NOT stop machine to raise bowl.
13. Close apron to reduce spillage.
14. If engaged, release transmission hold control.
15. If locked, release differential lock switch. Accelerate to traveling speed.
N OT E
Cutting edge is narrower than scraper bowl. Repeated cuttings within the same slot will
result in bowl getting jammed in slot. Minimum slot width should be about 1-1/2 times
machine width.
16. On successive passes at fill area, use straddle cutting to achieve the best results.
Traveling
0005
C AU T I O N
Maneuver around large obstructions when traveling. Driving over large objects may
damage transmission case.
N OT E
The following instructions are intended to provide basic procedures on traveling with
scraper, loaded or unloaded.
1. Travel only on haul roads that have been authorized for your use and have been properly maintained. Avoid
making deep ruts in road. Travel next to previous track to reduce rutting.
2. Loaded machines always have the right of way, unless otherwise directed by supervisor.
N OT E
Speed is governed by smoothness of haul road, by favorable or adverse grades, and by
underfoot conditions. Keeping bowl low enhances stability at high speeds and on uneven
roads.
"Loping" is a rhythmic up-and-down motion ofthe machine. Slower speeds are necessary
if uneven surfaces create loping.
