throttle moves freely and returns to closed position). Being
carefulnottoendangeradjacentpersonnel,cleartheairhose
of accumulated dust and moisture. Attachment of a quick-
disconnect air coupling directly to the inlet threads of a
percussion tool can cause wear and failure of the coupling.
Should the coupling fail, severe injury can result from the
hose end violently whipping about. If a quick-disconnect air
coupling is used, separate the coupling from the tool with a
whip hose (1.5 feet minimum). Only use a whip hose with
fittings of hardened steel or other material which is at least
comparablyresistantto shock.Donot usehoseto liftorlower

Cracked chisels or implements are
hazardous. Visually inspect the chisel
orimplementforcracksbeforeuse.Makeapracticeofhaving
all chisels magnifluxed before resharpening. Destroy and
discard any chisel or implement that shows a crack.
Correct selection of the chisel or other implement is impor-
tant. Dull edges on the chisel or moil point cause the energy
of the percussion blow to be absorbed by the tool itself,
instead of the workpiece, increasing the chance of chisel
breakage. When operating percussion tools in explosive or
flammable environments, use only non-sparking chisels or
implementssuchasthosemade fromberylliumcopper.Also,
do not use cupped rivet sets with Cleco percussion tools to
drive nails. Blows not centered on the nail can cause the nail
to ricochet off the work and strike the user.

Safety Recommendations
Foryoursafetyandthe safetyofothers,readand understand
the safety recommendations before operating any percus-
sion tool.
Always wear protective equipment and clothing.
For additional information on eye protection, refer to Federal
OSHA Regulations, 29 CFR, Section 1910.133, Eye and
Face Protection, and ANSI Z87.1, Occupational and Educa-
tional Eye and Face Protection. This standard is available
fromtheAmericanNationalStandardsInstitute,Inc.,11West
42nd Street, New York, NY 10036.
Hearing protection is recommended in high noise areas
(above85 dBA). Closeproximity ofadditionaltools, reflective
surfaces, process noises, and resonant structures can sub-
stantially contribute to the sound level experienced by the
operator. For additional information on hearing protection,
refertoFederalOSHARegulations,29CFR,Section1910.95,
Occupational Noise Exposure, and American National Stan-
dards Institute, ANSI S12.6, Hearing Protectors.
Gloves and other protective clothing should be worn as
required.Properlyfitted glovescushionvibration andprotect
the fingers from pinching, scuffing and scraping and must be
used when guiding the chisel on a workpiece.
Cleco percussion tools are designed to operate on 90 psig
(6.2 bar) maximum air pressure. Excessive air pressure can
damage the plunger and increases sound levels. Installation
ofafilter-regulator-lubricatorintheairsupplylineaheadofthe
tool is highly recommended. Before the tool is connected to
the air supply, check the throttle for proper operation (i.e.,

WARNING!
Explosive Hazard.
Use only nonsparking chisels or
implements in explosive or
flammable environments.
Impact Hazard. Ejected chisels can cause
serious injury or even death.
Disconnect air before changing chisels.
Do not operate unless chisel is in contact
with workpiece.
Do not point tool in direction of any person.
Use safety retainers on tool and retainer
type chisels.

cold and dampness, diet, smoking and work practices are
thought to contribute to the conditions. 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, or
fingers is advised to consult a physician. If it is determined
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, reassigning workers to other jobs, rotating jobs, chang-
ing 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.
• 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.
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
numberofdifferentmanufacturers.Thesegloves,wraps,and
wrist supports are designed to reduce and moderate the
effects of extended vibration exposure and repetitive wrist
trauma.Since theyvarywidely indesign, material,thickness,
vibration reduction, and wrist support qualities, it is recom-
mended that the glove, tool wrap, or wrist support manufac-
turer be consulted for items designed for your specific appli-
cation. Proper fit of gloves is important. Improperly fitted
gloves may restrict blood flow to the fingers and can
substantially reduce grip strength.
This information is a compilation of general safety practices
obtained from various sources available at the date of pro-
duction. However, our company does not represent that
everyacceptablesafety practice isconsideredherein, or that
abnormal or unusual circumstances may not warrant or
require additional procedures. Your work may require addi-
tionalspecificsafetyprocedures.Followtheseproceduresas
required by your company. For more information, see the

if the throttle is accidently engaged. Use of a self-relieving
valve within reach of the user of the tool is highly recom-
mended.
Do not operate or trigger any percussion tool unless the
chisel, scaling tool, rivet set, or other implement is in the tool
andincontactwiththeworkpieceorworksurface.Neverpoint
any percussion tool in the direction of another person or
yourself, or deliberately eject a chisel. Failure to do so can
cause serious injury and/or damage the tool.
Chisel or rivet set retainers are recommended and furnished
asstandard equipment.Periodic inspection of the retainer
forwearordamageisrecommendedsincethesedevices
can receive heavy abuse, particularly if the tool is run off
the workpiece. Damaged retainers are dangerous, and
can allow the ejection of a chisel or other implement.
They must be replaced as necessary. Only use safety
retainer type chisels, as shown in the operating instruc-
tions and service manual. Also, it is good safety practice to
erect suitable barriers to protect persons in surrounding or
lower work areas from possible ejected tools.
Some individuals
may be suscep-
tible to disorders
of the hands and
arms when per-
forming tasks
consisting of
highly repetitive
motions and/or
exposure to ex-

Cumulative
trauma disorders such as carpal tunnel syndrome and ten-
donitis may 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
developgraduallyover periods of weeks,months, and years.
It is presently unknown to what extent exposure to vibrations
or repetitive motions may contribute to the disorders. Heredi-
