Safety Recommendations
Wheels or accessories known to have been subjected to any of
the conditions above can burst violently and should be destroyed
rather than risk their use by someone who may not notice that
they are damaged.
Do not operate 116/136 RA grinder without a wheel guard if used
with Type 1 (straight) or Type 27 (depressed center) wheels.
Guard must not be modified, and any guard damaged or bent must
be replaced. Grinder must be used such that opening in guard is
away from operator.
CHECK FLANGE
A Type 1 wheel grinder's flanges must be relieved, free
of nicks that might cause stress concentrations on the
wheel which can cause cracks. Blotters must be used
and be as large in diameter as the flanges. Diameters of
driving and outer flange must be equal and measure at
least 1/3 dia. of the wheel. If flanges are less than 1/3 dia.
of wheel, do not use grinder or select proper wheel.
Spindle end nut must be tightened firmly against outer
flange to insure necessary friction against blotters to
drive wheel. Caution: Overtightening can cause wheel breakage. Type
1 breakage can also occur if:
• Outer flange is left off
• Outer flange is reversed
• A washer is used in place of either flange
• Outer and driving flange are different diameters
• Blotters are not used
• Wheel is side loaded (Grind on periphery only!)
Check spindle
and driving
flange on grind-
ers used with
Type 27 (de-
pressed center)
w h e e l s .
Spindles must
not be bent and
threads must be
free of any dam-
age that might
keep a wheel from being centrally mounted or seated properly
against the driving flange. The spindle end nut should be tightened
to prevent wheel slippage and satisfactorly transfer the driving
torque of the spindle to the wheel through the adapter assembly.
COLLET EQUIPPED TOOLS
The collet should be checked to assure it is in good operating
condition and is secure to the tool. Accessories should be inserted
to full depth of the collet. Avoid excessive overhang and/or exces-
sive down force that can result in vibration or a bent spindle.
Possible loss or ejection of accessory can result. Collet equipped
116/136 RA grinders are intended for use with small carbide burrs
and mounted wheels only. Do not use these tools for Type 1 or Type
27 wheel grinding. If your application calls for a Type 1 or Type 27
wheel, consult your Cleco representative for a wheel grinder equipped
with the proper wheel guard.
BEGINNING GRINDING OPERATION
Before using or after mounting a wheel or accessory, tool must be
run for one minute in a protected enclosure to check the integrity of
the wheel or accessory. During this time or any other time, no one
should stand in front or in line of the wheel or accessory. When
starting work with a cold wheel, apply it gradually to the workpiece
until it becomes warm. Do not continue to use a grinder if:
• It is not equipped with proper wheel guard
• It starts to vibrate
• You sense changes in tool speed or an unusual increase
in noise that would indicate tool is running at excessive
speed
• You notice excessive end play in spindle
• You hear any unusual sound from grinder
RETURN THE TOOL TO THE TOOL CRIB FOR SERVICE IMMEDI-
ATELY!
Some individuals may be
susceptible to disorders
of the hands and arms
when performing tasks
consisting of highly re-
petitive motions and/or
exposure to extended vi-
bration. Cumulative
trauma disorders 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 disorders.
Hereditary factors, vasculatory or circulatory problems, 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 before it
becomes a debilitating injury. Any user suffering prolonged symp-
toms 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 determined 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, reas-
signing 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 proper selection of the correct type of grinder is an important
ergo nomic consideration. Each application should be carefully
considered and the tool chosen that will minimize the stresses on
the operator that can lead to the onset of cumulative trauma
disorders. Some tasks require more than one type of tool to obtain
the optimum operator/tool/task relationship. Cleco has a complete
selection of tools including vertical, straight, angle, and extended
grinders that make possible the correct ergonomic match of the
operator, tool, and task.
The following suggestions will help reduce or moderate the effects
of repetitive work motions and/or extended vibration exposure:
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.
