Safety Recommendations
For your safety and the safety of others, read and understand the
safety recommendations and operating instructions before operating any power tool with this balance arm.
!
WARNING
Always wear protective equipment:
!
WARNING
Impact resistant eye protection
must be worn while operating
or working near this tool.
For additional information on eye protection and face protection,
refer to Federal OSHA Regulations, 29 Code of Federal Regulations, Section 1910.133., Eye and Face Protection, and American
National Standards Institute, ANSI Z87.1, Occupational and Educational Eye and Face Protection. Z87.1 is available from the American
National Standards Institute, Inc., 11 West 42nd Street, New York,
NY 10036.
Keep hands and fingers away
from jaws or pinch points that
will entrap hands or fingers.
Keep hands and fingers away from pinch points or any placements
of squeezer that will entrap hands or fingers.
!
!
CAUTION
Personal hearing protection is
recommended when operating
or working near this tool.
Hearing protection is recommended in high noise areas 85 dBA or
greater. The operation of other tools and equipment in the area,
reflective surfaces, process noises 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 and training
in the use and fit of hearing protection devices may be necessary.
For additional information on hearing protection, refer to Federal
Regulations, Section 1910.95, Occupational Noise Exposure, and
American National Standards Institute, ANSI S12.6, Hearing Protectors.
CAUTION
Before any tool is used, check the throttle (if so equipped) for proper
operation (i. e., throttle moves freely and returns to closed position).
Being careful not to endanger adjacent personnel, clear an air hose
of accumulated dust and moisture. Before connecting a tool to an air
supply or removing a tool from service, 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.
!
WARNING
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.
Avoid repeated bending of wrists and hands.
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
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 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, vasculatory or circulatory problems, exposure to
cold and dampness, diet, smoking and work practices are thought to
contribute to the conditions.

Safety Recommendations
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, or fingers is advised to consult a physician.
If it is determined that the symptoms 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, repositioning the workpiece or redesigning the workstation, reassigning 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.
The following suggestions will help reduce or moderate the effects
of repetitive work motions and/or extended vibration exposure:
Extension
OK
Neutral
Avoid
Flexion
Avoid
Radial Deviation
Avoid
OK
Neutral
Ulnar Deviation
• 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
For more information on the safe use of portable air tools, see the
latest edition of ANSI B186.1, Safety Code for Portable Air Tools,
available from the American National Standards Institire, Inc. 11
West 42nd Street, New York, NY 10036.
This information is a compilation of general safety practices obtained
from various sources available at the date of production. However,
our company does not represent that every acceptable safety
practice is offered herein, or that abnormal or unusual circumstances may not warrant or require additional procedures. Your work
may require additional specific safety procedures. Follow these
procedures as required by your company.
• 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
Avoid
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 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, vibration reduction, and wrist support
qualities, it is recommended that the glove, tool wrap, or wrist support
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.
Warning Labels
The warning labels found on these tools are an essential part of this
product. Labels should not be removed. Labels should be checked
periodically for ligibility. Replace warning labels when missing or
when the information can no longer be read. Replacement labels
can be ordered as any spare part.
The air compression riveter model 44 develops a squeezing force
of 4400 pounds and the 28 develops 2800 pounds when it is operated with an air pressure of 90 PSI. The dimensions of the jaw have
been designed to ensure the users safety. Changes in the jaw (by
grinding or any other machining process) should not be made. If an
unauthorised change is made, the manufacturer will be released
from its products liabilfty. To ensure product safety, no changes or
modifications should be made from its product liabilfty. The same is
true if the compression riveter is used with higher than specified air
pressure.

OPERATION
TROUBLESHOOTING
The rivet squeezers operate on 90psig (6.2bar) compressed
air supply using a 1/4" hose 8' in length and if additional
hose is needed the next size larger should be connected to
the 1/4" hose.
The squeeze is not correct:
• Wrong adjustment
• Check the distance between the rivet sets (often to small)
It is recommended to use oiled air in order to increase seals
and pistons lifetime. A lubricator regulating filter should be
supplied to the installation.
• Adjust the rivet sets
The squeezing force is too weak:
•This riveter is equipped with a two pneumatic pistons cylinder, pushing a roller bearing by means of a wedge.
• Check the air pressure
•When pushing the lever (push and turn), air pressure is
directed to the two rear chambers of the two pistons through
the valve.
• Check the rivet set adjustment
•The wedge at the end of the piston is a two angle shape
so:
The tool does not work:
• Check the condition of the wedge
• Take the valve flap apart
•At the end of the stroke, the moving jaw moves
quickly (quick feed maximum force).
•At the end of the stroke, the moving jaw moves
slowly (working feed maximum force).
•The rivet squeezer must be adjusted so that the maximum
squeezing force takes place at the end of the cylinder stroke
(see adjustment section).
Releasing the lever will automatically send both pistons back
for to their starting positions - The holder comes back to
home position by spring.
As described above, the maximum riveting force being at
the end of the pistons stroke, the holder final position must
be checked at the end of this stroke.
Because these squeezers are to be used on sheet metal of
various thickness, the holder is equipped with a knob adjustment to take care of this.
Adjust holder so clearance between the two rivet sets meets
the riveting thickness (flush head or cupped set). In that
position, the riveter delivers the maximum force.
•To adjust the squeezer, it is recommended to use a sample
piece of sheet metal.
•The above steps must be followed to adjust the machine
to avoid damage to the tools - the manufacturer can not be
held responsible for damage caused to the tool by not following the above instructions.
