For your safety and the safety of others, read and under-
stand the safety recommendations and operating instruc-
tions before operating a drill.
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,OccupationalandEducational Eye 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
pressure above 90 PSIG or worn motor components can
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.
Drilling operations may produce hazardous fumes and/or
dust. To avoid adverse health effects utilize adequate

selected, fitted, used and maintained in accordance with
Occupational Safety and Health Administration and other
applicable regulations. Read the material safety data
sheet of any cutting fluids or materials involved in the
drilling process.
Follow good ma-
chineshoppractices.
Rotating shafts and
moving components
canentangleanden-
trap, and can result
in serious injuries.
Neverwearlonghair,
loose-fitting clothes,
gloves, ties, or jew-
elry when working
with or near a drill of
any type.
Cleco drills are designed to operate on 90 psig (6.2 bar)
maximum air pressure. If the tool is properly sized and
applied,higherair pressure is unnecessary. Excessive air
pressure increases the loads and stresses on the tool
parts 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
dust and moisture. Before removing a tool from service or
changing a drill bit, tap, reamer, or any accessory make
sure the air line is shut off and drained of air. This will
prevent the tool from operating if the throttle is accidently
engaged.
Suddenandhighreactiontorquemay
be experienced with any drill if:
• drill motor stalls by excessive load being applied to drill
bit or drill bit snags on material being drilled.
• on break-through when the drill bit passes through the
material being drilled. User must be prepared to resist
torque.

Safety Recommendations
a problem can be addressed before it becomes a debilitat-
ing injury. Any user suffering prolonged symptoms of
tingling, numbness, blanching of fingers, clumsiness or
weakened grip, nocturnal pain in the hand, or any other
disorderoftheshoulders,arms,wrists,orfingersisadvised
toconsult aphysician.If itisdetermined thatthesymptoms
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, reposi-
tioningtheworkpieceor 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.
Thefollowing suggestionswillhelp reduceormoderate the
effectsofrepetitiveworkmotionsand/orextendedvibration
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

•Useappropriatelysizedchuckkeytosecurelytightendrill

•Use care when drilling because of the possibility of the
cutting tool bending or breaking.
Tools equipped with chuck capacity over 1/4" should have
at least one handle offset at a right angle to drill axis to
counteracttorquedevelopedbytool.Iftoolisequippedwith
a chuck over 3/8" capacity, two handles at right angles to

Always use a dead handle with low RPM —high torque
tools.
Some individuals may be susceptible to disorders of the
handsandarmswhenperformingtasksconsistingofhighly
repetitive motions and/or exposure to extended vibration.
Cumulative trauma disorders such as carpal tunnel syn-
drome and tendonitis can 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 peri-
ods 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,smokingandworkpracticesarethoughtto
contribute to the conditions. Any tool operator should be
awareofthefollowing warningsignsandsymptomsso that
CAUTION !
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.

Safety Recommendations
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
anumber of different manufacturers.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. Improperly fitted gloves may restrict blood
flow to the fingers and can substantially reduce grip
strength.

approximately 30 seconds. The lubricator is properly set
when a light stain of oil collects on the paper. Excessive
amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for
an extended period of time (overnight, weekend, etc.), it
shouldreceivea generousamountof lubricationatthattime
and again when returned to service. The tool should be
stored in a clean and dry environment.
Application of the tool should govern how frequently it is
greased. It is recommended that the idler gears, gear pins
and bearings receive a generous amount of NLGI 2-EP
grease.Greaseisappliedbyunscrewing(lefthandthreads)

SERVICE INSTRUCTIONS — REASSEMBLY
REASSEMBLY—GENERAL
All parts should be washed in a solvent and inspected for
damage or wear. Particular attention should be given to all
bearings, gears, gear pins, and rotor blades as failure of
these parts could cause damage to more expensive parts.
Particular attention should be paid to the governor assem-
bly, replacing any of its' parts that show wear or damage. It
is recommended that new rotor blades be installed at each
repaircycle. Ifnot replaced,the usedones mustmeasurea
minimum of 3/16" (4.7mm) at both ends. Failure of these
partscouldcausedamagetomoreexpensivecomponents.
All gears, gear pins, and open bearings should receive a
generousamountofNLGI2-EPgreaseduringreassembly.
Reassembly of all of the various subassemblies is in the
reverse order of disassembly; however, the following para-
graphs list some of the more important reassembly proce-
dures.

bearing plate. Press the bearing plate assembly (press on
thebearing's inner race) onto the rear rotor shaft untilthere
is approximately .0015" (.038mm) clearance between the
rear bearing plate and rotor. Install the cylinder with the
slotted end toward the front bearing plate.
