at either end.

Neutral

Ulnar Deviation

Avoid

• 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 accessories (the primary source of vibration
when using a grinder is an accessory that is out of

balance, out of round, untrue, or possibly any combina-

tion of all three; avoid excessive overhang of accessory
in collet)
• Use carbide burrs that are sharp, as dull burrs require
more force and effort to remove material
• Keep tool well maintained and replace worn parts (a
preventive maintanance program with scheduled inspec-
tions is highly recommended)

Work gloves with vibration reducing liners and wrist supports 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 de-
signed to reduce and moderate the effects of extended vibration
exposure and repetitive wrist trauma. Since they vary widely in
design, material, thickness, vibration reduction, and wrist support
qualities, it is recommended that the glove, tool wrap, or wrist
support manufacturer be consulted for items designed for your
specific application. WARNING! Proper fit of gloves is important.
Improperly fitted gloves may restrict blood flow to the fingers and
can substantially reduce grip strength.
USE QUALITY ABRASIVE WHEELS
The primary source of vibration when using a portable grinder is an
abrasive wheel that is out of balance, out of round, untrue, or
possibly any combination of all three.

The use of quality abrasive wheels which are well balanced, round,
and true is highly recommended as they have been found to
significantly reduce vibration. Some abrasive wheels lose their
balance, roundness, and trueness as they wear from use. Because
of the abusive nature of the vibration caused by out of balance, out
of round, and untrue condition of some abrasive wheels, it is felt that
these wheels are more suseptible to failure. Excessive vibration
may signal eminent wheel failure. Out of balance abrasive wheels
are dangerous. Flat spotting of the abrasive wheel, caused by
grinding the wheel to a stop after the power has been shut off can

result in changes to the balance and shape of the wheel. Be sure the
grinding wheel has stopped before setting the tool down. Set the tool in
a tool rest or tool holder when not in use.

WIRE BRUSHES
If a grinder is used for wire brushing applications the same
problems of balance, roundness, and truth as experienced with
abrasive wheels prevail. Use quality wire brushes.

USE A PREVENTIVE MAINTENANCE PROGRAM
Tool abuse or poor maintenance procedures can amplify and
contribute to the vibration produced by the abrasive wheel. A
preventive maintenance program featuring scheduled periodic
inspections and proper maintenance is the best way to assure
safety in your portable grinding operations. A well managed pro-
gram can, for example, detect such things as speed variations due
to wear, flanges or spindles that have been damaged from abuse,
or bad bearings damaged by foreign matter or lack of lubrication.
Problems such as these can affect the wheel trueness when the
grinder is running and contribute to the vibration. Rotor blades that
are worn or chipped can lock up the motor and damage motor
components. Rotor blades should be checked periodically and
replaced if they measure less than 3/16" (4.7mm) at either end.

Proper repair procedures and the use of original Cleco service parts
and bearings rather than substitutes will return the tool to factory
specifications of precision and balance, and minimize vibration.

PROPER LUBRICATION
An automatic in-line filter-regulator-lubricator is recommended as
it increases tool life and keeps the tool in sustained operation. The
in-line lubricator should be regularly checked and filled with a good
grade of 10W machine oil. Proper adjustment of in-line lubricator is
performed by placing a sheet of paper next to exhaust ports and
holding throttle open approximately 30 seconds. Lubricator is
properly set when a light stain of oil collects on paper. Excessive
amounts of oil should be avoided.

STORAGE
In the event it becomes necessary to store tool for an extended
period of time (overnight, weekend, etc.), it should receive a gener-
ous amount of lubrication at that time and run for several seconds
to distribute oil before disconnecting from air supply. This will
reduce corrosion and displace water that may be trapped in tool.
