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.

Trowel Arm Adjustment
Use the following procedure to check and adjust trowel arms,
and check for worn or damaged components when it becomes
apparent that the trowel is finishing poorly or in need of routine
maintenance.
Look for the following indications. Trowel arm alignment, worn
spider bushings or bent trowel arms may the cause.

2.Rotate blades into position under Z-Clips. Ensure that the
blades are rotated in the direction of travel when the machine
is in operation or use the engine to rotate the blades into
position.
3.Attach the blade tie-downs (item #3) to the far side of the ZClip brackets (item #4) with tie-down knobs (item #2) as
shown in figure 35.
4.Check to make certain that the blade edges are secured
under the Z-Clips and the tie-downs are secured completely
over the edges of the blade bar before the machine is put back
into operation.
