Electrical safety
1. power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs
with grounded power tools.
Unmodified plugs and matching outlets
will reduce risk of electric shock.
2. Do not expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric shock.
3. Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the power tool. Keep cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase
the risk of electric shock.
4. When operating a power tool outdoors,
use an extension cord
suitable for outdoor use.
Use of a cord suitable for outdoor use
reduces the risk of electric shock.
5. If operating a power tool in a damp
location is unavoidable, use a Ground
Fault circuit Interrupter (GFcI)
protected supply. Use of a GFCI
reduces the risk of electric shock.
personal safety
1. Stay alert, watch what you are
doing and use common sense when
operating a power tool. Do not use
a power tool while you are tired or
under the influence of drugs, alcohol
or medication. A moment of inattention
while operating power tools may
result in serious personal injury.
2. use personal protective equipment.
Always wear eye protection.
Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
3. Only use safety equipment
that has been approved by an
appropriate standards agency.
Unapproved safety equipment may
not provide adequate protection.
Eye protection must be ANSI-approved
and breathing protection must be
NIOSH-approved for the specific
hazards in the work area.
power tool use and care
1. use the correct power tool for your
application. The correct power tool
will do the job better and safer at the
rate for which it was designed.
2. Do not use the power tool if the Switch
does not turn it on and off.
Any power tool that cannot be
controlled with the Switch is
dangerous and must be repaired.
3. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing
power tools. Such preventive safety
measures reduce the risk of starting
the power tool accidentally.
4. Store idle power tools out of the
reach of children and do not allow
persons unfamiliar with the power tool
or these instructions to operate the
power tool. Power tools are dangerous
in the hands of untrained users.

5. Maintain power tools. check for
misalignment or binding of moving
parts, breakage of parts and any other
condition that may affect the power tool’s
operation. If damaged, have the power
tool repaired before use. Many accidents
are caused by poorly maintained power tools.
6. use the power tool, accessories and
tool bits etc. in accordance with these
instructions, taking into account the
working conditions and the work to
be performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.

GROuNDING
TO pREVENT ELEcTRIc SHOcK AND DEATH
FROM INcORREcT GROuNDING WIRE cONNEcTION:
check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the tool.
Never remove the grounding prong from the plug. Do not use the tool if the power cord or
plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will
not fit the outlet, have a proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three prong plugs
3-prong plug and Outlet
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.
(See 3-prong plug and Outlet.)
Extension cords
1. Grounded tools require a
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.
Page 6 For technical questions, please call 1-888-866-5797. Item 61245
