Working the Truck
relivalve operation.
NEVER ' JUMP DUMP' t he machine 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,
extensive stresses. (refer to g.5-16)
Once the load has been dumped, push the
control lever down into the 'FLOAT' position
to allow the body's weight to lower it to the
chassis. If the body does not begin to lower by
its weight, push the control lever down into the
'LOWER' position and power the body down
until it begins to lower by gravity. Then release
the control lever into the 'FLOAT' position.
Note:
For the truck running stably that should
be operated the hoisting handle slowly while
the body hoisting period and lowing period.
5.5 Empty Return
Make sure the body is completely lowered, the
body control lever is in the 'FLOAT' position,
and the transmission is shifted to the correct
range before releasing the brakes and moving
away from the dump site.
Except for the above, the procedure for
returning empty to the loading area is the
same as that given earlier for 'HAULING'.
WARNING
DO NOT drive the truck with the body
up. Apart from effecting the stability of
the truck, there can be severe danger
from contacting overhead electric
cables, trees, or bridges over the haul
route.
