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 g.5-13).
Before raising the body, make sure the rear
wheels are on rm 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 button to hold the
machine stationary(refer to g.5-14).
Push the body control lever back into the
'RAISE' position and The engine speed should
be holds within 1000rpm for stably during the
starts and ends peroid of rasing the body.
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 relief valve
operation.
NEVE R 'JUM P DUMP' the m achine by
bouncing the rear tyres against a stop block,
or otherwise jarring the body in its raised
position to dislodge stuck or frozen material.
The tremendous loads that this practice
develops on the body pin area, chassis
and hydraulic system can cause needless,
