PROPOSITION 65 WARNING
Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drillingandother construction activities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of thesechemicals are:
Leadfromlead-basedpaints.
Crystallinesilica frombricks.
Cementandother masonry products.
Arsenicandchromiumfromchemically
treatedlumber.
Your risk from these exposures varies,
dependingon how often you dothistype
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with
approved safety equipment, such as
dust masks that are specially designed
to filter out microscopic particles.

SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
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.

TOWING GUIDELINES
TOWING SAFETY PRECAUTIONS
CAUTION
Check with your county or state safety towing 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 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 45 MPH, however
before towing your mixer, check your local state, and
county vehicle towing requirements. Recommended offroad towing is not to exceed 10 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 16 (Tire Wear
Troubleshooting).
When towing of the mixer is required, place the drum in
the up position (mouth facing upwards).
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 U-clamp nuts, torque suspension
hardware as referenced in the maintenance section of
this manual.
Avoid sudden stops and starts. This can cause skidding,
or jackknifi ng. Smooth, gradual starts and stops will
improve gas milage.
Avoid sharp turns to prevent rolling.
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.
Tow Bar to Vehicle Connection (Coupler Only)
Check the vehicle hitch ball, and mixer's coupler for 1.
signs of wear or damage. Replace any parts that are
worn or damaged before towing.
Use only a 2-inch ball diameter (towing vehicle), this will 2.
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.
After tow bar has been connected to mixer (see next 3.
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 Connection (Pintle and Loop)
Make sure the bumper on the towing vehicle is 1.
equipped to handle either a pintle or loop type tow bar
confi guration.
After tow bar has been connected to mixer (see next 2.
page), secure either type of tow bar to the towing vehicle,
following state and county towing regulations.

MAINTENANCE (MIXER)
TIRES/WHEELS/LUG NUTS
Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing the
trailer wheels it is important the wheels, tires, and axle are
properly matched.
CAUTION
DO NOT attempt to repair or modify a wheel.
DO NOT install an inter-tube to correct a
leak through the rim. If the rim is cracked,
the air pressure in the inter-tube may cause
pieces of the rim to explode (break-off) with great force
and can cause serious eye or bodily injury.
TIRES WEAR/INFLATION
Tire infl ation pressure is the most important factor in tire
life. Pressure should be checked cold before operation. DO
NOT bleed air from tires when they are hot. Check infl ation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 8 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.

MAINTENANCE (MIXER)
Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
Start all wheel lug nuts by hand.1.
Torque all lug nuts in sequence. See Figure 22. 2. DO
NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defi ned
by Table 9.
