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.

SAFETY INFORMATION
CAUTION
NEVER allow any person or animal to
stand underneath the equipment while
lifting.
Ride-on trowels are very heavy and
awkward to move around. Use proper
heavy lifting procedures and DO NOT
attempt to lift the trowel by the guard rings.
NEVER lift trowel with the operator on the machine.
NOTICE
The easiest way to lift the trowel is to utilize the lift loops
that are welded to the frame. These lift loops are located
to the left and right sides of the operator’s seat.
A strap/chain can be attached to these lift loops, allowing
a forklift or crane to lift the trowel up onto and off of a slab
of concrete. The strap or chain should have a minimum
of 2,000 pounds (1,000 kg) lifting capacity and the lifting
gear must be capable of lifting at least this amount.
NEVER transport trowel with fl oat pans attached unless
safety catches are used and are specifi cally cleared for
such transport by the manufacturer.
NEVER hoist the trowel more than three feet off the
ground with fl oat pans attached.
Before lifting, make sure that the lift loops are not
damaged.
Always make sure crane or lifting device has been
properly secured to the lift loops of the equipment.
ALWAYS shutdown engine before transporting.
NEVER lift the equipment while the engine is running.
Tighten fuel tank cap securely and close fuel cock to
prevent fuel from spilling.
Use adequate lifting cable (wire or rope) of suffi cient
strength.
CAUTION
Check with your local county or state safety
towing regulations, in addition to meeting
Department of Transpor tation (DOT)
Safety Towing Regulations, before towing
your trowel.
In order to reduce the possibility of an accident while
transporting the trowel on public roads, ALWAYS
sure the trailer that supports the trowel and the towing
vehicle are mechanically sound and in good operating
condition.
ALWAYS shutdown engine before transporting
