When charging, mixing, or dumping a batch of plaster
or mortar the
drum lock pin
should be placed to the
left
(when viewing the mixer from the towpole end) of
the drum stop block which is welded to the front side of
the drum. See Figure 22.
This will allow the operator to use both hands on the
drum handle during dumping. Please note that when
the lock pin is placed to the left, the drum will be
maintained in the vertical position as the paddles rotate.
To discharge the material the operator should hold the
dump handle with
both hands
and rotate the drum to
discharge the desired amount of material.
