SETTING UP THE MIXER
Grounding
This product must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electrical shock by providing an escape for the electric current.
This product is equipped with a cord that has a grounding wire and an appropriate
grounding plug. The plug must be inserted into an outlet that is properly installed
and grounded in accordance with all local codes and ordinances.
WARNINGCheck with a qualified electrician or service
person if grounding instructions are not
completely understood or if in doubt as to
whether product is properly grounded.
WARNINGImproper installation of the grounding plug can
result in a risk of electric shock. If repair or
replacement of the cord or plug is necessary, do
not connect the grounding wire to either flat
blade terminal.
The insulation wire with green or green and yellow stripes on the outer surface is
the grounding wire. Check with a qualified electrician if the grounding instructions
are not completely understood, or if in doubt about whether the product is properly
grounded. DO NOT modify the plug provided. If it will not fit into the outlet, have
the proper outlet installed by a qualified electrician.
This product is designed for use in 100 to 240 Volt operation. The power
requirements of your unit will be outlined on the nameplate.
The non explosion-proof model is for use on a nominal 120-volt circuit and has a
grounding plug that looks like the plug illustrated in the figure below. Make sure
that the product is connected to an outlet having the same configuration as the p lug.
No adapter should be used with this product.
Note: If product has a nameplate for nominal 220-vo lt circuit, make
sure the proper grounded outlet is used.

SETTING UP THE MIXER
LEVELING
The customer must level the mixer. Although the unit is shipped on casters for ease
of positioning the mixer, all 4 feet must be extended firmly to the floor. Variations
on the floor will necessitate adjusting the leveling feet to ensure proper operation
and to minimize vibration.
CAUTIONImproper leveling may cause severe vibration
while the mixer is operating.
1.Roll the unit into its intended location.
2.Lower the four (4) leveli ng feet to the ground. Each of the four leveling
feet can be adjusted independently. Using the front of the mixer as a
position guide, turn the foot in a clockwise direction to lengthen, or in a
counter-clockwise direction to shorten.
IMPORTANT: The feet should carry the load; not the casters.
Check the stability of the mixer on the floor by making
sure that the mixer is resting on all four feet, not on its
casters. All casters must rotate freely.
3.Verify that the mixer is level by gripping its sides and gently attempting
to rock the machine. It should not move.
4.Lock the leveling feet into place by tightening the upper locknuts to the
mixer bottom with a 3/4" wrench.
Note: Should additional leveling be necessary, loosen the upper
locknuts and repeat steps 2 - 3.

2.Slide the motor drive pulley onto the shaft and into the same position
measured during removal in Step 9, REMOVING THE MOTOR.
3.Place the key inside the keyway in the motor drive pulley and tighten the
set screw. The key should be seated in the driveshaft keyway. It should
be positioned in the same way as on the old motor (as noted in Step 9,
REMOVING THE MOTOR).
4.Push the circular retaining ring into the motor pulley.
5.Viewing the shaft end of the motor, confirm that the rotation of the
motor is CW (clockwise). Refer to the diagram on the side of the motor
for a detailed wiring diagram.
6.Lift the motor, with the wires pointing downward, into position and
fasten to the motor mounting bracket with the four (4) screws.
7.Before completely tightening the screws, manually turn the rotating
mechanism one full revolution to verify that the motor does not interfere
with the rotating mechanism.
Note: If there is interference, move the motor slightly to correct
the problem before tightening the screws.
8.Connect L1, L2, and ground wires to the motor . Refer to the diagram on
the side of the motor to verify the motor wiring for clockwise rotation as
viewed from the shaft end.
9.Reassemble the tubing connector nut onto the conduit box.
10.Close the motor cover plate with the screw.
