Description / Abstract:
Scope and purpose
This standard applies to portable, handheld internal combustion
engine-powered machines, which use a rotating cut-off (abrasive)
wheel that is center-mounted on and driven by a spindle shaft, and
designed for cutting construction materials such as asphalt,
concrete, stone, and metal.
The requirements in this standard apply to machines using up to
406-mm (16-in) cut-off wheels. If the machine is designed for
larger than 406-mm (16-in) cut-off wheels, the requirements of this
standard shall be considered. The requirements listed may apply to
machines designed for larger cut-off wheels.
Cut-off wheel design and safety specifications are not included
in this standard.
The effective implementation date of this standard shall be two
(2) years after the publication date and shall apply to all
products built after that date. Manufacturers may also comply with
the requirements of this standard any time after the publication
date.
"ANSI/OPEI B175.4-2013" and "ANSI B175.4-2013" may be used
interchangeably wherever referenced or required in this
standard.
Purpose
This standard establishes safety and environmental requirements
to reduce the risk of injury associated with the use of portable,
hand-held internal combustion engine-powered machines using a
rotating cut-off (abrasive) wheel.
