This is meant to highlight sections of safety standards published by the American National Standards 

Institute and the Occupational Safety and Health Administration. This is not meant to replace those 

standards but only highlight certain areas. 

When care is taken to ensure that the right tool is operated properly, and safety and maintenance 

procedures are followed, accidents can be avoided. Read and follow all instructions and directions. 

Comply with all rules governing the use of power tools, personal protective equipment and equipment 

guards.

Remember - machines, attachments and accessories must be used only for the purpose for which 

they were designed. Safety reasons and product liability prohibit any modifi

cations to tools. Any 

attachments or accessories must be agreed to in advance with an authorized technical 

representative of H&S Tool, Inc. 

Operation Instructions and Safety Precautions

The grinding equipment must be approved for the 

rated speed of the machine. The rated speed, 

marked on the machine, should not be exceeded. 

Be sure to learn the proper handling and storage 

of abrasive wheels and inserted tooling. 

Inspect the wheel guard for any signs of  wear and 

that it is properly mounted to the tool. Any guard 

showing signs of wear such as bends, chips, 

nicks, or cracks should be replaced. 

Always wear eye and hearing protection, and when 

necessary, other personal protective equipment 

such as gloves, an apron, and helmet. Properly 

fitted protective clothing cushion the operator from 

vibration exposure and help prevent minor scrapes 

that might occur as a result of guiding the tool along 

the workpiece. 

Additional information on eye protection is available 

in the following national regulatory standards.

1) Federal OSHA Regulations 29 CFR, Section

1910.133 (Eye and Face Protection)

2) ANSI Z87.1 (Occupational and Educational Eye

and Face Protection)

Check hose size and air pressure. The air pressure at the tool shall 

not exceed 90 psi (6.2 bar). All hoses should be inspected regularly 

and kept away from heat, oil and sharp edges. Be sure the tool is 

secured to the air hose.

Measure the speed of grinders every 20 hours of actual use or once 

per week, whichever comes fi

rst.

Measure speed of all types of grinders after maintenance or repair, 

whenever a grinder is issued from the tool crib and at each wheel 

change. Several readings should be taken.

This form of inspection should be made with the grinding wheel or 

tooling removed.
