shown in figure 9-21. Shake the bucket to loosen dirt
from within. After the load is dumped, back away, lower
the bucket to the carrying position, and return to the
digging area.
CAUTION
A loaded bucket must never be transported
in the fully raised position.
NOTE: Dump trucks should be loaded from the
driver’s side whenever possible. When the truck is being
loaded, be sure the driver either stays in the cab (on
cab-protected trucks) or away from the truck and loader.
When loading from a bank, keep the cutting edge
flat, as shown in figure 9-22. Tilting the bucket back too
far forces the flat of the cutting edge against the bank,
preventing the bucket from digging. This maneuver is
nonproductive and causes waste of power, time, and
possible damage to the bucket cylinders and linkage.
When stockpiling material, move each load only
once and keep the travel distance short. When possible,

locate stockpiles as close to the jobsite as possible
without hindering other work on the jobsite.
When clearing a rocky area, remove the small and
loose rocks first. Large rocks and other solid objects can
then be loosened and moved easier.
