General Information
Breakages/Personal Injury
In the event of on-machine breakage of Norton abrasive products, call your local Norton distributor immediately. Whether involving personal injury
or not, the abrasive user should leave the equipment and other evidence undisturbed until a Norton sales representative has been notified and
conducts an investigation. Prompt action on the part of abrasive users, distributor, and Norton sales personnel is important to ensure swift
determination of the breakage cause and to guard against recurrence.
Safe Operating Practices
Safe operating practices must be part of every grinding wheel user’s operation. The greatest efficiency and lowest overall abrasive cost can be
realized only if proven care and use techniques become standard practice.
• Be sure to read any safety material/guidelines provided with the
abrasive product.
• Always check the wheel for cracks or damage before use.
• Always properly maintain your machine; especially governors on
pneumatic machines and linkage on floorstand machines.
• Never use the incorrect air, hydraulic or electric power supply.
• Never mount grinding wheels directly on electric motors.
• Never mount grinding wheels on the wrong size machine for the
grinding wheel.
• Before mounting the wheel, use a tachometer to measure the
spindle speed.
• Ensure the mounting flanges, backplate or adapter supplied by the
machine manufacturer are used and kept in good condition. ANSI
Safety Requirement B7.1 provides wheel mounting requirements.
Check mounting flanges for equal and correct diameter and use
blotters when supplied.
• Always mount, true and dress the wheel in conformance with the
guidelines published in the ANSI Safety Requirements B7.1.
• Ensure the correct wheel guard is in place before starting the wheel.
Allow the wheel to come up to full operating speed before starting
to grind for a minimum of one minute, and stand out of the plane
of rotation.
• NEVER use a high speed air sander as a portable grinder.
• NEVER use grinding wheel with a rated speed less than that of
the grinder.
• NEVER exceed the maximum operating speed marked on the
wheel being used. The following formula may be used to calculate
wheel speed:
SFPM = Spindle Speed in RPM x Wheel Dia. in inches x .262
• Avoid dropping or bumping the wheel.
• When not using the wheel, store the wheel in its original packing
materials. This protects the wheel from chips and cracking, as well
as provides easy identification of the wheel.

AVOID BODILY CONTACT WITH
AN ABRASIVE PRODUCT
Most abrasive wheels, discs, belts, etc. rotate at high speeds in order to perform their
function effectively. Accidental contact with one of these products during rotation may result
in an injury ranging from minor (cut/abrasion) to severe (loss of a body part). When using an
abrasive product always consider the following:
• Pay attention! Never make contact with
a rotating object.
• Contain long hair and do not wear loose
clothing, or dangling objects such as ID
badges, ties, jewelry, or anything that
may catch on the rotating object.
• If gloves are worn, they must be
tight fitting.
• Prevent accidental start-up of the
machine during abrasive product
changes or during equipment repair/
maintenance by disconnecting machines
from their power source.
• Most (there are some exceptions)
abrasive products require a guard.
Guards have many functions such as;
protecting the operator from a breakage,
deflecting sparks, collecting dust/swarf
and aiding in keeping body parts from
coming into contact with rotating
abrasive product. Always use a properly
adjusted guard.
Avoid contact with rotating abrasive products! A cut-off wheel will cut, a grinding wheel will
grind, and a coated abrasive product will abrade. These products cannot tell the difference
between a work piece (like steel) and you! So remember, as always, play it safe at the wheel
and avoid bodily contact with any rotating objects!
