SILICOSIS/RESPIRATORY WARNINGS  
WARNING 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.  
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.

MAINTENANCE (MIXER)  
TIRES/WHEELS/LUG NUTS  
LUG NUTTORQUE REQUIREMENTS  
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.  
It is extremely important to apply and maintain proper wheel  
mounting torque. 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:  
1. Start all wheel lug nuts by hand.  
WARNING — Damaged Wheels  
2. Torque all lug nuts in sequence. See Figure 39. DO  
NOT torque the wheel lug nuts all the way down.Tighten  
each lug nut in 3 separate passes as defined by Table  
10.  
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.

engines) before cleaning the inside of the drum. If mixer  
is equipped with an electric motor remove power cord  
from AC power source. In addition make sure the  
clutch engagement lever is disengaged.  
4. Place “Do Not Operate” tag on mixer.  
5. Make sure the rear section of safety grate is connected  
to the mixing drum.  
6. At the end of each day’s operation, place mixer drum  
in an upright position and spray inside of tub  
immediately with water to prevent lumps of dried mortar  
or plaster from forming and contamination of future  
batches, DO NOT allow a buildup of materials to form  
on the blades or anywhere inside the drum.  
Figure 39. Wheel Lug Nuts Tightening Sequence  
7. Rotate mixer to dump position and remove debris.
