resistance path to carry electricity away from the
user, reducing the risk of electric shock.
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.
Your 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
Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked "Double Insulated" do not require
grounding. They have a special double insulation sys-
tem which satisfi es OSHA requirements and complies
with the applicable standards of
Underwriters Laboratories, Inc., the
Canadian Standard Association and
the National Electrical Code. Double
Insulated tools may be used in ei-
ther of the 120 volt outlets shown in
Figures B and C.
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. 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. Refer to the table shown to determine the
required minimum wire size.
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. When using more than one extension
cord to make up the total length, be sure each cord
contains at least the minimum wire size required. 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 wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure
it is marked with the suffi x "W-A" ("W" in Canada)
to indicate that it is acceptable for outdoor use.
• Be sure your extension cord is properly wired
and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a
qualifi ed person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

back will propel the tool in direction opposite to the
wheel’s movement at the point of snagging.
•
Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the ac-
cessory.
Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause
loss of control or kickback.
•
Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent
kickback and loss of control.
Safety Warnings Specifi c for Grinding and Abra-
sive Cutting-Off Operations:
•
Use only wheel types that are recommended for
your power tool and the specifi c guard designed
for the selected wheel.
Wheels for which the
power tool was not designed can not be adequately
guarded and are unsafe.
•
The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed towards
the operator.
The guard helps to protect operator
from broken wheel fragments and accidental contact
with wheel.
•
Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel.
Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied
to these wheels may cause them to shatter.
•
Always use undamaged wheel fl anges that are of
correct size and shape for your selected wheel.
Proper wheel fl anges support the wheel thus reduc-
ing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel
fl anges.
•
Do not use worn down wheels from larger power
tools.
Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and
may burst.
Additional Safety Warnings Specifi c for Abrasive
Cutting-Off Operations:
•
Do not jam the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut.
Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback
or wheel breakage.
•
Do not position your body in line with and be-
hind the rotating wheel.
When the wheel, at the
point of operation, is moving away from your body,
the possible kickback may propel the spinning wheel
and the power tool directly at you.
•
When wheel is binding or when interrupting a
cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never attempt
to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may
occur.
Investigate and take corrective action to
eliminate the cause of wheel binding.
•
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut.
The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
•
Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back.
Large workpieces tend to sag under their
own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of
the workpiece on both sides of the wheel.
•
Use extra caution when making a "pocketcut"
into existing walls or other blind areas.
The pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Safety Warnings Specifi c for Sanding Operations:
•
Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper.
Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing
of the disc or kickback.
Safety Warnings Specific for Wire Brushing
Operations:
•
Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
over stress the wires by applying excessive load
to the brush.
The wire bristles can easily penetrate
light clothing and/or skin.
•
If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard.
Wire wheel
or brush may expand in diameter due to workload
and centrifugal forces.
Additional Safety Warnings
•
Maintain labels and nameplates.
These carry
important information. If unreadable or missing,
contact a service facility for a free replacement.
•
WARNING:
Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause can-
cer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• 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 spe-
cially designed to fi lter out microscopic particles.
WARNING
Improperly connecting the
grounding wire can result in the risk of electric
shock. Check with a qualifi ed electrician if you
are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with
the tool. Never remove the grounding prong from
the plug. Do not use the tool if the cord or plug
is damaged. If damaged, have it repaired by a
service facility before use. If the plug will not
fi t the outlet, have a proper outlet installed by a
qualifi ed electrician.
Grounded Tools: Tools with Three Prong Plugs
Tools marked "Grounding Required" have a three
wire cord and three prong grounding plug. The plug
must be connected to a properly grounded outlet
(See Figure A). If the tool should electrically mal-
function or break down, grounding provides a low
