Safety Warnings
1.
Hold power tools by insulated gripping
surfaces when performing an operation
where the cutting tool may contact hidden
wiring or its own cord.
Contact with a
″live″ wire will make exposed metal parts
of the tool ″live″ and shock the operator.
2.
Take caution as some woods contain
preservatives such as copper
chromium arsenate (
CC
A) which can
be toxic
. When cutting these materials
extra care should be taken to avoid
inhalation and minimize skin contact.
3.
Exposure to aluminum oxide (a dust
generated from material removing processes)
can result in eye, skin, and respiratory
irritation. Always use a NIOSH (National
Institute for Occupational Safety and Health)
approved respirator and ANSI approved
safety goggles. Avoid skin exposure. Proper
ventilation in the work area is required.
4.
Maintain labels and nameplates on the tool.

sustained electrical shock.
11.
WARNING: Some
dust created by power
sanding, sawing, grinding, drilling, and
other construction activities,
contain
s
chemicals known [to the State of California]
to cause cancer, birth defects or other
reproductive harm. Some examples of
these
chemicals
are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement or
other
masonry products
• Arsenic and chromium from
chemically
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.
(California Health & Safety
Code
§ 25249.5,
et seq.
)
12.
WARNING: Handling the cord on this product
will expose you to lead, a chemical known
to the State of California to cause cancer,
and birth defects or other reproductive harm.
Wash hands after handling.
(California Health & Safety
Code
§ 25249.5,
et seq.
)
13.
The warnings, precautions, and instructions
discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the
operator that common sense and caution are
factors which cannot be built into this product,
but
must be supplied by the
operator.
Vibration Safety
This tool vibrates during use.
Repeated
or
long
-
term
exposure to vibration may
cause temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To
reduce the risk of vibration-related injury:
1.
Anyone using vibrating tools regularly
or for an extended period should first
be examined by a doctor and then have
regular medical check-ups to ensure
medical problems are not being caused
or worsened from use. Pregnant women
or people who have impaired blood
circulation to the hand, past hand injuries,
nervous system disorders, diabetes, or
Raynaud’s Disease should
not
use
this
tool.
If
you
feel
any
symptoms related to
vibration (such as tingling, numbness,
and white or blue fingers), seek medical
advice as soon as
possible.
2.
Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3.
Wear suitable gloves to reduce the
vibration effects on the user.
4.
Use tools with the lowest vibration
when there is a
choice.
5.
Include vibration-free periods
each day of work.
6.
Grip tool as lightly as possible
(while still keeping safe control
of
it).
Let the tool do the work.

1.
Tools marked with “Grounding Required”
have a three wire cord and three prong
grounding plug. The plug must be connected
to a properly grounded outlet. If the tool
should electrically malfunction or break
down, grounding provides a low resistance
path to carry electricity away from the
user, reducing the risk of electric
shock.
2.
The grounding prong in the plug is
connected through the green wire inside
the cord to the grounding system
in
the
tool.
The
green wire in the cord must be
the only wire connected to the tool’s
grounding system and must never be
attached to an electrically “live” terminal.
3.
The tool must be plugged into an appropriate
outlet, properly installed and grounded in
accordance with all codes and ordinances.
The plug and outlet should look like those in
the preceding
illustration.

ords
1.
Grounded
tools require a
Grounded tools require aGrounded
three wire
extension
cord.
Double
Insulated
tools can use either
a two or three wire extension cord.
2.
As the distance from the supply outlet
increases, you must use a heavier gauge
extension cord. Using extension cords with
inadequately sized wire causes a serious
drop in voltage, resulting in loss of power
and possible
tool
damage.
(See
Table
A.)
3.
The smaller the gauge number of the wire,
the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher
current than a 16 gauge cord.
(See
Table
A.)
4.
When using more than one extension cord
to make up the total length, make sure
each cord contains at least the minimum
wire size required.
(See
Table
A.)
5.
If you are using one extension cord for more
than one tool, add the nameplate
amperes
and use the sum to determine the required
minimum cord size.
(See
Table
A.)
6.
If you are using an extension cord
outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate
it is acceptable for outdoor use.
7.
Make sure the extension cord is properly
wired and in good electrical condition.
Always replace a damaged extension
cord or have it repaired by a qualified
electrician before using it.
8.
Protect the extension cords from
sharp objects, excessive heat,
and damp or wet areas.
