Operation Instructions and Safety Precautions
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 modifications to tools. Any
attachments or accessories must be agreed to in advance with an authorized technical
representative of H&S Tool, Inc.
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.

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
9
per week, whichever comes first.
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.
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)
