Personal hearing protection is
recommended when operating
or working near this tool.
Safety Recommendations
For your safety and the safety of others, read and under-
stand the safety recommendations and operating instruc-
tions before operating any tool.
Always wear protective equipment:
For additional information on eye protection and face
protection,refertoFederalOSHARegulations,29Codeof
Federal Regulations, Section 1910.133., Eye and Face
Protection, and American National Standards Institute,

in the area, reflective surfaces, process noises and reso-
nant structures can substantially contribute to, and in-
crease the noise level in the area. Excessive air pressure
above 90 PSIG or worn motor components can also
increase sound level emitted by tool. For additional infor-
mationonhearingprotection,refertoFederalRegulations,
Section1910.95,OccupationalNoiseExposure,andAmeri-
can National Standards Institute, 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,higherairpressureis unnecessary.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
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.
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
tunnelsyndromeandtendonitismaybecausedoraggra-
vated by repetitious, forceful exertions of the hands and
arms. Vibration may contribute to a condition called
Raynaud's Syndrome. These disorders develop gradu-
ally over periods of weeks, months, and years. It is
presentlyunknowntowhatextent exposuretovibrations
or repetitive motions may contribute to the disorders.
Hereditary factors, vasculatory or circulatory problems,
exposureto coldanddampness,diet,smokingandwork
practices are thought to contribute to the conditions.

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,butarenotlimitedto,repositioningtheworkpieceor
redesigningtheworkstation,reassigningworkerstoother
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
tooltoobtaintheoptimumoperator/tool/taskrelationship.
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 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,
itisrecommendedthattheglove,toolwrap,orwristsupport
manufacturer be consulted for items designed for your
specific application. WARNING! Proper fit of gloves is
important.Improperlyfitted glovesmayrestrictblood
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.Thein-linelubricatorshouldberegu-
larlycheckedandfilledwithagoodgradeof10Wmachine
oil.Properadjustmentofthein-linelubricatorisperformed
by placing a sheet of paper next to the exhaust ports and
holding the throttle open for approximately 30 seconds.
The lubricator is properly set when a very light stain of oil
collectsonthe paper.Excessive amounts ofoil shouldbe
avoided.
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
greasethroughthegreasefittingsafter40hoursofopera-
tion.
STORAGE
Intheeventthatitbecomesnecessarytostorethetoolfor
an extended period of time, it should receive a generous
amountoflubricationatthattimeandagainwhenreturned
to service. The tool should be stored in a clean and dry
environment.Thisinhibitscorrosionof theprecisioninter-
nal components and bearings.
TORQUE ADJUSTMENT
The 55MTC nutrunner is designed to develop maximum
rated torque at 90 psig. The torque setting is achieved by
entering a number within the tool's torque range into the
torquecontrolmonitor.Seecatalogfortorquerangeoftool.
The torque setting entered into the torque control monitor
must not exceed maximum torque range of tool or the
automatic shut-off device will not function and the tool will
operate as a stall tool. Operator should be prepared to
resist torque reaction until throttle is released.
AIR SUPPLY
For maximum performance, use a 1/2" I.D. air hose no
longer than 8' in length. If additional length is required, a
5/8" or larger hose should be connected to the 1/2" hose.
Beingcarefulto avoid endangeringadjacent personnel or
yourself, theairhoseshouldbeclearedofaccumulateddirt

REASSEMBLY — GENERAL
Thetoolis reassembled inthe reverse orderof disassem-
bly. Clean all parts thoroughly in kerosene and inspect for
damageorwear.Checkallbearingsforwearwhichcanbe
detected by excessive end play and/or roughness which
would indicate a brinelled condition. The rotor blades
should be replaced at every repair cycle if they measure
less then 1/4" (6.4mm) at either end. All gear teeth, bear-
ings, and pins should receive a close inspection and be
replaced if necessary.
NOTE:Duringreassemblyofthecompletetool,itisimpor-
tant that the motor be free. After the tool is completely
assembled, the square drive spindle should turn freely
using a small hand wrench. If the spindle does not turn
freely,themotorshouldbecheckedforproperspacing.Do
not run the tool until the spindle turns freely. Failure to do
this could result in damage to motor components.
Motor Unit

Makesuretheouterbearingraceisfirmlyseatedinbearing
plate. Clamp the rotor lightly in the vise with the threaded
end up and slip the rear bearing plate assembly onto the
rotor shaft far enough for the bearing lock nut to start.
Tighten the lock nut until there is approximately .0015"
clearance between the rotor and bearing plate. The outer
bearing race should be firmly seated and the rotor held
forward when checking this clearance.
Pack both rotor bearings with a good grade of No. 2 Moly
grease after assembly of the motor unit.

If a 87.15kohm shunt calibration resistor is used, no calculations are required. The full scale value of the transducer may be
used for the calibration value.
If a 110kohm resistor is used, the calibration value is 79.3% of rated full scale value (see calculation below).
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 55 series and a torque monitor with a 110 kohm calibration resistor.
The values are: FS = 51.6
Rbr = 700ohm
Vo = .002
Rcal = 110,000ohm
700ohm 1 1
% FS = --------------------------- X ------ X ----- = 79.3%
