Grinding/cutting/drilling of masonry, concrete, metal and
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.In addition, 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
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal and
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
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.
The WM-70 plaster and mortar mixer is equipped with a number of safety decals. These decals are provided for operator
safety and maintenance information. Figure 1 below illustrates these decals as they appear on the machine. Should any
of these decals become unreadable, replacements can be obtained from your dealer or the MQ Parts Department.

CAUTION
In addition to meeting Department of Transportation
(DOT) safety towing regulations, check your local
county or state safety towing regulations before towing
the mixer.
In order to reduce the possibility of an accident while
transporting the mixer on public roads, ALWAYS make
sure the towing vehicle is mechanically sound and in
good operating condition.
ALWAYS shut down the engine before transporting and
place the fuel valve in the OFF position.
ALWAYS inspect the hitch and coupling for wear. NEVER
tow a mixer with defective hitches, couplings, chains, etc.
Check the tire air pressure on both towing vehicle and
mixer. Mixer tires should be infl ated to 50 psi cold.
Also check the tire tread wear on the vehicle and mixer.
ALWAYS make sure the mixer is equipped with a safety
chain.
NOTICE
follow the rules below.
DO NOT

handling batteries that contain sulfuric acid.
ALWAYS properly attach the mixer’s safety chains to
the towing vehicle.
The maximum speed for highway towing is 55 MPH unless
posted otherwise. Recommended off-road towing is not to
exceed 15 MPH or less depending on type of terrain.
Avoid sudden stops and starts. These can cause skidding
or jackknifi ng. Smooth, gradual starts and stops will
improve towing.
Avoid sharp turns to prevent rolling.
The mixer should be adjusted to a level position at all
times when towing.
Raise and lock the mixer drum in the UP position when
towing.

The gasoline engine used in this equipment has been
designed to reduce harmful levels of carbon monoxide
(CO), hydrocarbons (HC) and nitrogen oxides (NOx)
contained in gasoline exhaust emissions.
This engine has been certifi ed to meet US EPA evaporative
emissions requirements in the installed confi guration.
Attempting to modify or make adjustments to the engine
emission system by unauthorized personnel without proper
training could damage the equipment or create an unsafe
condition.
Additionally, modifying the fuel system may adversely affect
evaporative emissions, resulting in fi nes or other penalties.
Emission Control Label
The emission control label is an integral part of the emission
system and is strictly controlled by regulation(s).
The label must remain with the engine for its entire life.
If a replacement emission label is needed, please contact
your authorized engine distributor.
Check with your county or state towing safety
regulations department before towing your mixer.
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 recommendations 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. Check the tire tread wear on both vehicles.
Check the wheel mounting lug nuts with a torque wrench.
Torque the lug nuts as described in the Maintenance
section of this manual.
Check the tightness of the axle mounting hardware.
Torque the suspension hardware as described in the
Maintenance section of this manual.
Avoid sudden stops and starts. These can cause skidding
or jackknifing. Smooth, gradual starts and stops will
improve gas mileage.
NOTICE
If the mixer tow bar is deformed or damaged, replace
the entire tow bar. NEVER tow the mixer with a defective
tow bar. The possibility exists of the trailer separating
from the towing vehicle.
NOTICE
DO NOT tow or lift the mixer unless the mixing drum
is completely empty.
ALWAYS make sure the mixer is equipped with a
safety chain.
ALWAYS attach the trailer’s safety chain to the frame of
the towing vehicle.
ALWAYS make sure that the towing vehicle’s directional,
backup, and brake lights are working properly.
Remember that in most cases the maximum speed for
highway towing is 55 mph unless otherwise posted.
Check your local, state and county vehicle towing
requirements before towing your mixer. Recommended
off-road towing speed is 15 mph or less depending on
the type of terrain.
If the mixer is disconnected from the towing vehicle while
parked, place chock blocks underneath the wheels to
prevent rolling.
Inflate tires to the correct pressure and inspect tires
for damage or excessive wear. See Table 10 for
tire wear troubleshooting.
When towing of the mixer is required, place the drum in
the UP (mouth facing upwards) position.
NOTICE
To prevent the drum from tipping, ALWAYS make sure
the drum latch pin (Figure 2) is placed to the RIGHT
(when viewing the mixer from the tow bar end) of the
drum stop block, which is welded to the front of the
drum. Make sure the latch pin is fully engaged (locked).
This will prevent the drum from rotating during transport.

1. Check the vehicle hitch ball and the 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 for the 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 ball failure or separation
of the coupler and ball.
3. After the tow bar has been connected to the mixer
(Figure 3–Figure 6), securely attach the mixer’s coupler
to the hitch ball on the towing vehicle. Make sure the
lock lever is in the DOWN (locked) position and the
safety pin is inserted.
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.
TOWING GUIDELINES
2. After the tow bar has been connected to the mixer
(Figure 3–Figure 6), 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 nyloc nut
(grade 5) when securing either tow bar to the towing
vehicle.
