MAYCO C30HDGA CONCRETE PUMP • OPERATION MANUAL — REV. #1 (09/09/19) — PAGE 3

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.Inaddition, 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.
