Repetitive work motions and/or vibration
may cause injury to hands and arms.
Use minimum hand grip force consistent
with proper control and safe operation.
Keep body and hands warm and dry.
Avoid anything that inhibits blood circulation.
Avoid continuous vibration exposure.
Keep wrists straight.
WARNING
!
Avoid repeated bending of wrists and hands.
Safety Recommendations
before it becomes a debilitating injury. Any user suffering
prolonged symptoms of tingling, numbness, blanching of
fingers, clumsiness or weakened grip, nocturnal pain in the
hand, or any other disorder of the shoulders, arms, wrists,
or fingers is advised to consult a physician. If it is deter-
mined that the symptoms are job related or aggravated by
movements and postures dictated by the job design, it may
be necessary for the employer to take steps to prevent
further occurrences. These steps might include, but are not
limited to, repositioning the workpiece or redesigning the
workstation, reassigning workers to other jobs, rotating
jobs, changing work pace, and/or changing the type of tool
used so as to minimize stress on the operator. Some tasks
may require more than one type of tool to obtain the
optimum operator/tool/task relationship.
The following suggestions will help reduce or moderate the
effects of repetitive work motions and/or extended vibration
exposure:
• Use a minimum hand grip force consistent with
proper control and safe operation
• Keep body and hands warm and dry (cold weather is
reported to be a major factor contributing to Raynaud's
Syndrome)
• Avoid anything that inhibits blood circulation
—Smoking Tobacco (another contributing
factor)
—Cold Temperatures
—Certain Drugs
• Tasks should be performed in such a manner that the
wrists are maintained in a neutral position, which is
not flexed, hyperextended, or turned side to side
• Stressful postures should be avoided — select a tool
appropriate for the job and work location
• Avoid highly repetitive movements of hands and
wrists, and continuous vibration exposure (after
each period of operation, exercise to increase blood
circulation)
• Use quality abrasive wheels
• Keep tool well maintained and replace worn parts
Work gloves with vibration reducing liners and wrist sup-
ports are available from some manufacturers of industrial
work gloves. Tool wraps and grips are also available from
a number of different manufacturers. These gloves, wraps,
and wrist supports are designed to reduce and moderate
the effects of extended vibration exposure and repetitive

Before beginning operations or after
mounting a wheel, the tool must be run
for one (1) minute in a protected enclo-
sure to check the integrity or the wheel.
During this time or any other time, no
one should stand in front of or in line of
the wheel. When starting work with a
cold wheel, apply it gradually to the
workpiece until the wheel becomes
warm.
DO NOT CONTINUE TO USE A GRINDER IF:
• It is not equipped with the proper wheel guard
• The speed rating of the wheel is less than the
speed of the grinder
• It starts to vibrate
• You sense any changes in tool speed or an
unusual increase in noise output that would
indicate the tool is running at excessive speed.
• You notice excessive end play in the spindle
• You hear any unusual sound from the grinder
RETURN THE TOOL TO THE TOOL CRIB FOR SERVICE
IMMEDIATELY!
Some individu-
als may be sus-
ceptible to dis-
orders of the
hands and
arms when per-
forming tasks
consisting of
highly repetitive
motions and/or
exposure to extended vibration. Cumulative trauma disor-
ders such as carpal tunnel syndrome and tendonitis may
be caused or aggravated by repetitious, forceful exertions
of the hands and arms. Vibration may contribute to a
condition called Raynaud's Syndrome. These disorders
develop gradually over periods of weeks, months, and
years. It is presently unknown to what extent exposure to
vibrations or repetitive motions may contribute to the disor-
ders. Hereditary factors, vasculatory or circulatory prob-
lems, exposure to cold and dampness, diet, smoking and
work practices are thought to contribute to the conditions.
Any tool operator should be aware of the following warning
signs and symptoms so that a problem can be addressed
