Starting (electric only)
1. Using an adequate size extension cord (see Table 5),
connect one end of the extension cord to the plug on the
electric motor, connect the other end to the power source.
Make sure the motor is configured for the proper operating
voltage.
2. Set the electric motor's ON/OFF switch (Figure 7) to the
ON position.
Mixing Dumping
1. The paddle shaft inside the drum should be rotating at
this time.
2. Add a small amount water to the mixing drum.
3. Lift the mixing bag compound onto the steel safety grate
over the bag cutter and let the contents fall into the drum.
Add more water if desired and mix compound to desired
consistency.
4. 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 21.
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.
8. Place the belt slip lever (Figure 20) in the mix position. This
will tilt the engine placing tension on the V-belts enabling
the shaft to rotate.

Be sure to stand clear of the dump handle (Figure 22) when
the mixer is operational. Any binding of material between the
mixer blades and the drum will cause the drum handle to move
to the discharge position and could cause bodily harm.
