Extended Die Grinder
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 your compressor
daily.

Safety Instructions
The following instructions are furnished
as general guidelines for use of your
pneumatic tool. They cannot compre-
hensively cover all possible or conceiv-
able 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.
11 West 42nd Street

The use of the word “shall” in the
following instructions, indicates that
adherence to the particular require-
ment 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 manufac-
turer. 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 protec-
tion at the joint being separated. Syn-
thetic 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.
