other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis.Inaddition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentionedabove.
WARNING
Grinding/cutting/drillingofmasonry,concrete,metaland
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity,or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations.Water should be used for dust
suppression when wet cutting is feasible. When the
hazardsfrom inhalation ofdust,mists and fumes cannot
be eliminated, the operator and any bystanders should

ELECTRIC MOTOR COMPONENTS
ELECTRIC MOTOR
For lubrication care and operation of the electric motor,
refer to your electric motor instruction booklet furnished
with the motor.
Protect the electric motor from dust as much as possible
and keep ventilating openings clean.
The electric motor used on this mixer is single-phase,
1.5 HP @120/240 VAC motor. Pay special attention to the
nameplate on the electric motor when supplying power to
the electric motor. Applying incorrect power to the motor
can severely damage the motor and may cause serious
bodily injury!
Always make certain that the correct voltage is being
supplied to the motor. The input voltage requirements can
be found on the electric motor's nameplate.
ELECTRIC MOTOR POWER CONNECTIONS
A 12-inch electrical cable (Figure 6) is provided with the
electrical motor for hookup to a power source.
The electric motor supplied with the mixer is configured from
the factory for 120 VAC grounded operation.
Motors can burn out when the line voltage falls 10% below the
voltage rating of the motor. Failure to use proper voltage will
cause the motor to overheat and actuate the overload switch.
If overload protection should actuate because of improper
voltage or any other malfunction, turn the main switch on the
motor to the "OFF" position and correct the problem, press
the reset switch button, and turn the main switch to the "ON"
position.
CAUTION
DO NOT spray water at any time on the electric motor.
DO NOT operate electric motor in an explosive
environment.
NOTICE
It is strongly recommended that all electrical wiring be
done by a licensed electrician.Pay special attention to
the nameplate on the electric motor. Make certain that
the voltage supplied to the electric motor matches the
required operating voltage printed on the nameplate.
ELECTRIC MOTOR VOLTAGE CHANGE SWITCH
1. ALWAYS make certain the electric motor's ON/OFF
switch is in the "OFF" position and the power cord has
been disconnected from the power source.
2. Remove the voltage change lock-out bolt and nut
(Figure 5). Change the position of the voltage change
toggle switch from 120 VAC to 240 VAC. The mixer is
factory wired for 120 VAC operation.
3. Re-install the voltage change lock-out bolt and nut.
Figure 5. Voltage Change Switch
4. Important!, when changing the input voltage to the
electric motor from 120 to 240 VAC, the plug on the
electric motor power cord must also be changed. See
Table 6 and Figure 6.

TOWING GUIDELINES
TOWING SAFETY PRECAUTIONS
To reduce the possibility of an accident while
transporting the mixer on public roads, always make
sure that the mixer towing components and the towing
vehicle are in good operating condition and both units
are mechanically sound.
The following list of suggestions should be used when
towing the mixer:
Make sure that the hitch and coupling of the towing
vehicle are rated equal to, or greater than the trailer
"gross vehicle weight rating" (GVWR).
ALWAYS inspect the hitch and coupling for wear. NEVER
tow the mixer with defective hitches, couplings, chains
etc.
CHECK the tire air pressure on both the towing vehicle
and the trailer. Also check the tire tread wear on both
vehicles.
ALWAYS make sure the mixer is equipped with a "Safety
Chain."
ALWAYS attach trailer's safety chain to the frame of
towing vehicle.
ALWAYS make sure that the towing vehicle's directional,
backup, and brake lights are working properly.
Remember in most cases the maximum speed unless
otherwise posted for highway towing is 55 MPH, however
before towing your mixer, check your local state, and
county vehicle towing requirements. Recommended off-
road towing is not to exceed 15 MPH or less depending
on type of terrain.
Place chocked blocks underneath wheels to prevent
rolling , while parked, if disconnected from towing
vehicle.
Inflate tires to correct pressure, inspect tires for cuts, and
excessive wear. See Table 9 (Tire Wear Troubleshooting).
When towing of the mixer is required, place the drum in
the up position (mouth facing upwards).
Avoid sharp turns to prevent rolling.
CAUTION
Check with your county or state safety towing
regulations department before towing your mixer.
ALWAYS make sure that the fuel valve lever is in the
OFF position (gasoline models only).
Check wheel mounting lug nuts with a torque wrench.
Torque wheel lug nuts as described in the maintenance
section of this manual.
Check tightness of axle mounting hardware, torque
suspension hardware as referenced in the maintenance
section of this manual.
Avoid sudden stops and starts.This can cause skidding,
or jackknifing. Smooth, gradual starts and stops will
improve gas milage.
DO NOT tow or lift the mixer unless the mixing drum is
completely empty.
TOW BAR TO VEHICLE (COUPLER ONLY)
1. Check the vehicle hitch ball, and mixer's coupler for
signs of wear or damage. Replace any parts that are
worn or damaged before towing.
2. Use only a 2-inch ball diameter (towing vehicle), this will
match the mixer's 2-inch coupler. Use of any other ball
diameter will create an extremely dangerous condition
which can result in separation of the coupler and ball
or ball failure.
3. After tow bar has been connected to mixer (see next
page), attach mixer's coupler to the hitch ball on the
towing vehicle securely and make sure the lock lever
is in the down position (locked).
MIXER TOW BAR VEHICLE (PINTLE AND LOOP)
1. Make sure the bumper on the towing vehicle is
equipped to handle either a pintle or loop type tow
bar configuration.
2. After tow bar has been connected to mixer (see next
page), secure either type of tow bar to the towing
vehicle, following state and county towing regulations
3. As a minimum, use a 1/2-inch bolt and nylock nut grade
5 when securing either tow bar to the towing vehicle.
CAUTION
If the mixer tow bar is deformed or damaged replace
entire tow bar. NEVER tow the mixer with a defective
tow bar. There exist the possibility of the trailer
separating from the towing vehicle.
