When hauling dirt or rock from a borrow pit into
a fill area such as an earth-fill dam, the load
is usually dumped in a string with other loads
and the loads smoothed out with a crawler
tractor. When dumping on a fill of this type,
the operator usually works alone and picks his
own dumping place. To save bulldozer work
and cleaning up, the load should be dumped
as close as possible to the preceding load.
The operator should pull past the preceding
load, turn in line with the string and back his
truck until it is within a few feet of the last load.
This assures that the load will fall in the right
place.
No matter what kind of job the operator is
working, there are a few things which are
common to all jobs and which the operator
should observe. When dumping over a spoil
bank without a 'SPOTTER', know how close
the machine can safely approach the edge
under all weather conditions. If in doubt as to
dumping safety, dump the load a safe distance
from the edge so that it can be pushed over
the edge later(refer to fig.5-14).
Before raising the body, make sure the rear
wheels are on firm level ground. If one wheel
is higher than the other, a twisting strain is
imposed upon the body hinge pins, hoists
and chassis. Stop the machine, allow the
engine to slow to idle, shift the transmission
to 'NEUTRAL' and apply the brakes with the
Parking-Emergency Brake control to hold the
machine stationary(refer to fig.5-15).
Push the body control lever back into the
'RAISE' position and accelerate the engine.
Decelerate the engine to slow the raising
speed as the hoists approach their maximum
extension. When the body has been raised to
the desired height, release the control lever
into the 'HOLD' position until the body is to be
lowered. Do not hold the lever in the 'RAISE'
position when the hoists are fully extended
to prevent unnecessary hydraulic system
