Universal Tool UT7520C-1 User manual

UT7520C-1
PLEASE READ AND FOLLOW ALL WARNINGS
Read Operating Instructions
Always become familiar with all the
instructions and warnings before
operating any power tool.
Always Wear Approved
Eye Protection
Impact resistant eye protection
should meet or exceed the
standards as set forth in the United
States ANSI Z87.1, Occupational
and Educational Eye and Face
Protection. Look for the marking
Z87.1 on your eye protection to
insure that it is an approved style.
For further information, ANSI Z87.1,
Occupational and Educational Eye
and Face Protection, is available
from the American National
Standards Institute, Inc., 11 West
42nd Street, New York, NY 10036.
Hearing Protection is
Recommended
Hearing protection should be used
when the noise level exposure
equals or exceeds an 8 hour time-
weighted average sound level of 85
dBA. Process noise, reflective
surfaces, other tools being
operated nearby, all add to the
noise level present in your work
area. If you are unable to determine
your noise level exposure, we
recommend the use of hearing
protection.
Avoid Prolonged Exposure to
Vibration
Tools can vibrate during use.
Prolonged exposure to vibration or
very repetitive hand and arm
movements, can cause injury.
Stop using any tool if discomfort,
tingling feeling or pain occurs. You
should consult your physician
before resuming use of the tool.
90 PSIG Maximum
This tool is designed to operate at
an air pressure of 90 pounds per square
inch gauge pressure (90 PSIG) maximum,
at the tool. Use of higher air pressure
can, and may cause injury. Also, the use
of higher air pressure places the internal
components under loads and stresses
they were not designed for, causing
premature failure. The air supply should
be clean and dry, preferably lubricated.
For best results, drain the moisture from

Safety Instructions
The following instructions are furnished as
general guidelines for use of your pneu-
matic tool. They cannot comprehensively
cover all possible or conceivable uses of
the subject tool. For additional information
on the safe use of air tools, we advise you
to obtain a copy of ANSI B186.1 Safety
Code for Portable Air Tools, available from
the following source:
American National Standards
Institute, Inc.

The use of the word “shall” in the following
instructions, indicates that adherence to
the particular requirement is necessary to
conform to ANSI B186.1.
Tool Application and Usage
Portable tools shall be used only for the
purposes intended in their design and
within the capacity for which they were
intended and rated. It shall be the tool
owner’s and/or employer’s responsibility to
instruct each operator in the safe use of the
tool. Tools shall not be used without guards
and safety devices as furnished by the
manufacturer. Where an air tool is modified or
altered, the modifier shall provide the
safeguards to enable it to be safely used in
the operations intended and to comply with
any applicable provisions as contained in
ANSI B186.1.
Tool Installation
Pressure regulators shall be used to limit air
pressure to the rated pressure where the
supply pressure exceeds the tool’s rated
pressure. Air hoses and lines shall be
relieved of compressed air before being
disconnected or disjointed, unless there is
automatic valve closing protection at the joint
being separated. Synthetic lubricants which
can cause deterioration of elastomer seals
shall not be used in air systems of air tools.
Tool Maintenance
It shall be the tool owner’s and/or employer’s
responsibility to assure that tools are
maintained in a safe operating condition. Tool
maintenance and repair shall be performed by
authorized, trained, competent personnel.
Tools shall be disconnected from their
compressed air supply before repairs are
attempted. Repairs shall be consistent with
the manufacturer’s recommended proce-
dures. Tool, hoses and fittings shall be
replaced if unsuitable for safe operation. It
shall be the tool owner’s and/or employer’s
responsibility to keep required rating
markings and warnings on the tool in legible
condition.

WARNING:
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals
known to cause cancer, birth defects or
reproductive harm. Some examples of
these chemicals are:
•Lead from lead-based paints
•Crystalline silica from bricks, cement
and other masonry products
•Arsenic and chromium from chemi-
cally treated lumber
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to
these chemicals, work in a well-ventilated
area and work with approved safety
equipment such as those dust masks that
are specially designed to filter out
microscopic particles.
