CAUTION!
Personal hearing protection is
recommended when operating
or working near this tool.
For your safety and the safety of others, read and under-
stand the safety recommendations and operating instruc-
tions before operating a nutrunner.
Always wear protective equipment:
For additional information on eye protection and face
protection, refer to Federal OSHA Regulations, 29 Code
ofFederalRegulations,Section1910.133.,EyeandFace
Protection, and American National Standards Institute,
ANSIZ87.1,OccupationalandEducationalEye andFace
Protection. Z87.1 is available from the American National
Standards Institute, Inc., 11 West 42nd Street, New York,
NY 10036.
Hearing protection is recommended in high noise areas
85 dBA or greater. The operation of other tools and
equipmentinthearea,reflectivesurfaces,processnoises
and resonant structures can substantially contribute to,
and increase the noise level in the area. Excessive air
pressureabove90PSIGandwornmotorcomponentscan
also increase sound level emitted by tool. Proper hearing
conservation measures, including annual audiograms
andtrainingintheuseandfitofhearingprotectiondevices
may be necessary. For additional information on hearing
protection,refertoFederal Regulations,Section1910.95,
Occupational Noise Exposure, and American National
Standards Institute, ANSI S12.6, Hearing Protectors.
Cleco nutrunners are designed to operate on 90 psig (6.2
bar)maximumairpressure.Ifthetoolisproperlysizedand
applied,higherairpressureisunnecessary. Excessiveair
pressure increases the loads and stresses on the tool
parts, sockets, and fasteners and may result in breakage.
Installation of a filter-regulator-lubricator in the air supply
line ahead of the tool is recommended.
Before the tool is connected to the air supply, check the
throttleforproperoperation(i.e.,throttlemovesfreelyand
returns to closed position). Being careful not to endanger
adjacent personnel, clear the air hose of accumulated
dustandmoisture.Beforeconnectingatooltotheairhose
orremovingatoolfromserviceorchangingsockets,make
sure the air line is shut off and drained of air. This will
Safety Recommendations
prevent the tool from operating if the throttle is accidently
engaged.
When using right angle nutrunners, be sure the throttle is
positionedrelativetotheangleheadsothatthethrottlewill
not become wedged against an adjacent object in the
"ON"position due to torquereaction. The angle headmay
be repositioned with respect to the lever to accommodate
proper location for task. If tool is to be reversed, locate
throttle lever in a neutral position that will prevent entrap-
ment. Refer to operating instructions for additional infor-
mation.
It is essential for safe operation that any operator of a
nutrunner use good balance, sure footing, and proper
posture in anticipation of a torque reaction.
Toolswithclutchescanstallratherthanshut-offifadjusted
over maximum power output of tool, or if there is a drop in
air pressure. Operator must then resist stall torque until
throttle is released.
Tool balance arms are available to absorb the torque
reaction of the tool while balancing the weight of the tool
for improved ergonomic applications.
Some individuals may be susceptible to disorders of the
hands and arms when performing tasks consisting of
highly repetitive motions and/or exposure to extended
vibration. Cumulative trauma disorders such as carpal
tunnel syndrome and tendonitis may be caused or aggra-
vated by repetitious, forceful exertions of the hands and
arms. Vibration may contribute to a condition called
Raynaud'sSyndrome.These disorders develop gradually
over periods of weeks, months, and years. It is presently
unknown to what extent exposure to vibrations or repeti-
tive 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 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,
orfingersisadvisedtoconsultaphysician.Ifitisdetermined
that the symptoms are job related or aggravated by move-
ments 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 worksta-
tion,reassigningworkerstootherjobs,rotatingjobs,chang-
ing work pace, and/or changing the type of tool used so as
tominimizestress 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)
• 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
anumberofdifferentmanufacturers.Thesegloves,wraps,
and wrist supports are designed 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
yourspecificapplication.WARNING! Proper fitof gloves
is important. Improperly fitted gloves may restrict
blood flow to the fingers and can substantially reduce
grip strength.

OPERATING INSTRUCTIONS
LUBRICATION
An automatic in-line filter-lubricator-regulator is recom-
mended as it increases tool life and keeps the tool in
sustainedoperation. The in-line lubricator should beregu-
larlychecked andfilled withagood gradeof 10Wmachine
oil.Proper adjustmentof thein-line lubricator isperformed
by placing a sheet of paper next to the exhaust ports and
holdingthethrottleopenforapproximately30seconds.The
lubricatorisproperlysetwhenaverylightstainofoilcollects
onthepaper.Excessiveamountsofoilshould beavoided.
Application of the tool should govern how frequently it is
greased. It is recommended that the idler gears and right
angle gears receive a generous amount of NLGI 2-EP
grease through the grease fittings after 40 hours of opera-
tion.
STORAGE
In the event that it becomes necessary to store the tool for
an extended period of time, it should receive a generous
amountoflubricationatthattimeandagainwhenreturned
to service. The tool should be stored in a clean and dry
environment. This inhibits corrosion of the precision inter-
nal components and bearings.
