CAUTION!
Personal hearing protection is
recommended when operating
or working near this tool.
Safety Recommendations
For your safety and the safety of others, read and
understand the safety recommendations and operating
instructions before operating any tool.
Always wear protective equipment:
For additional information on eye protection and face
protection,refertoFederalOSHARegulations,29Code
of Federal Regulations, Section 1910.133., Eye and
FaceProtection,andAmericanNationalStandardsInsti-
tute,ANSIZ87.1,OccupationalandEducationalEyeand
Face 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
pressureabove90PSIGorwornmotorcomponentscan
also increase sound level emitted by tool. For additional
informationonhearingprotection,refertoFederalRegu-
lations,Section1910.95,OccupationalNoiseExposure,
andAmericanNational StandardsInstitute,ANSI S12.6,
Hearing Protectors.
Cleco tools are designed to operate on 90 psig (6.2 bar)
maximum air pressure. If the tool is properly sized and
applied, higher air pressure is unnecessary. Excessive
airpressure increasestheloadsandstresses onthetool
parts,sockets,andfastenersandmayresultinbreakage.
Installationofafilter-regulator-lubricator intheairsupply
line ahead of the tool is recommended.
Before the tool is connected to the air supply, check the
throttle for proper operation (i. e., throttle moves freely
and returns to closed position). Being careful not to
endangeradjacentpersonnel,cleartheairhoseofaccu-
mulated dust and moisture. Before removing a tool from
serviceorchangingsockets,makesuretheairlineisshut
off and drained of air. This will prevent the tool from
operating if the throttle is accidently engaged.
Someindividuals
may be suscep-
tible to disorders
of the hands and
arms when per-
forming tasks
consisting of
highly repetitive
motionsand/orexposuretoextendedvibration.Cumula-
tive trauma disorders such as carpal tunnel syndrome
and tendonitis may be caused or aggravated by repeti-
tious,forcefulexertionsofthehandsandarms.Vibration
may contribute to a condition called Raynaud's Syn-
drome. 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,
vasculatoryorcirculatoryproblems,exposuretocoldand
dampness,diet,smokingandworkpracticesarethought
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
tool operator should be aware of the following warning
signsandsymptomssothataproblemcanbeaddressed
beforeitbecomesadebilitatinginjury.Anyusersuffering

Safety Recommendations
determined that the symptoms are job related or aggra-
vated by movements and postures dictated by the job
design,itmaybenecessaryfortheemployertotakesteps
to prevent further occurrences. These steps might in-
clude, but are not limited to, repositioning the workpiece
or redesigning the workstation, reassigning workers to
other jobs, rotating jobs, changing work pace, and/or
changingthetypeoftoolusedsoastominimizestresson
theoperator.Sometasksmayrequiremorethanonetype
of tool to obtain the optimum operator/tool/task relation-
ship.
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 contrib
uting 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 posi-
tion, 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
supportsareavailablefromsomemanufacturersofindus-
trial 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 wrist trauma. Since they vary widely in design,
material,thickness,vibrationreduction,andwristsupport
qualities, it is recommended that the glove, tool wrap, or
wrist support manufacturer be consulted for items de-
signed for your specific application. WARNING! Proper
fit of gloves is important. Improperly fitted gloves
may restrict blood flow to the fingers and can sub-
stantially reduce grip strength.

OPERATING & SERVICE INSTRUCTIONS
The torque of the 8MT & 8M nutrunner is controlled by the use
ofapressureregulatortochangethestalltorqueofthetool.The
torque of the 8MA nutrunner is controlled by the use of a
CLECOMATIC automatic shut-off clutch. Accurate torque is
achieved by setting the CLECOMATIC clutch to the desired
torque.
CLUTCH ADJUSTMENT
Shut off air supply to the tool and rotate the adjustment cover,
No. 202829, 180°to uncover the adjustment slot in the clutch
housing. Rotate the spindle until the hole in the adjustment nut
isvisibleintheslot.Use
a 1/8" (3mm) diameter
pin to hold the nut. Use
a suitable tool to turn
the spindle in a coun-
terclockwisedirectionto
increase torque or
clockwise to decrease torque. Return the ad-
justment cover to its closed position after every
adjustment. Note: If the clutch is adjusted over the
maximumpoweroutputofthetool,theclutchwillnotfunction
and the tool will operate like a stall-type tool. Also, if the tool is
being operated at its upper torque limits, a drop in air pressure
could cause the clutch not to function due to a loss of motor
power and the tool will function like a stall-type tool.
FLOW VALVE
The flow valve No. 203036, can be adjusted with a screwdriver
clockwise to lower the RPM and counterclockwise to raise the
RPM of the tool.
AIR SUPPLY
Thetool isdesignedto operateat90 psig(6.2bar) airpressure.
Theairpressureshouldbecheckedatthetool'sairinletwhilethe
tool is running. For maximum performance, use a 5/16" I.D. air
hoseup to 8'inlength. Ifadditionallength isrequired,a 3/8"I.D.
or larger hose should be connected to the 5/16" I.D. hose.
LUBRICATION
An automatic in-line filter-regulator- lubricator is recommended
asitincreasestoollifeandkeepsthetoolinsustainedoperation.
Thein-linelubricatorshouldberegularlycheckedand filled with
a good grade of 10W machine oil. Proper adjustment of the in-
line lubricator is performed by placing a sheet of paper next to
theexhaustportsandholdingthethrottleopenapproximately30
seconds. The lubricator is properly set when a light stain of oil
collects on the paper. Excessive amounts of oil should be
avoided.
Applicationofthetoolshouldgovernhowfrequentlyitisgreased.
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 operation.
STORAGE
In the event that it becomes necessary to store the tool for an
extended period of time (overnight, weekend, etc.), it should
receivea generousamountof lubricationatthattimeandagain
when returned to service. The tool should be stored in a clean
and dry environment.

NOTE: If the trip rod is too long the tool can ratchet or not shut off.
If the tool has a drop in power or RPM the trip rod can be to short.
Remember the trip rod length is not the only factor that causes
these problems. If you feel sure you have cut the trip rod length
properly look for other problems.
MOTOR DISASSEMBLY
Use a soft-faced hammer to drive the rotor out of the front rotor
bearing. This will allow the cylinder and four (4) rotor blades to be
removedfromtherotor.Settherearbearingplateonthe vise jaws

CALIBRATION INSTRUCTIONS
In order to calculate the calibration value for the system in % full scale, the following formula may be used:
% FS = Rbr 1 1
------------------ X ----- X -----
2(Rcal) + Rbr Vo 2
Where Rcal = Calibration Resistor Value in ohms of the torque monitor used.
The following is an example of a 8 series tool and a torque monitor with a 110 kohm calibration resistor.
The values are: FS = 25.0 ft. lbs.
Rbr = 700ohm
Vo = .002
Rcal = 110,000ohm
700ohm 1 1
% FS = --------------------------- X ------ X ----- = 79.3%
2(110,000ohm) + 700ohm .002 2
Calibration Value = 25.0 (.793) = 19.8 ft. lbs.
*Calculated calibration value should be doubled if a torque monitor designed for use with a 350ohm bridge resistance
transducer is used.
