USE PROPER EXTENSION CORD. Make sure your exten-
sion cord is in good condition. When using an extension cord,
be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. Table 1
shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the cord.

Grinder safety warnings
Safety warnings common for grinding, sanding,
wire brushing, or cutting-off operations:
This power tool is intended to function as a grinder,
1.
sander, wire brush, hole cutter or cut-off tool. Read
all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure
to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
2. Operations such as polishing are not to be performed with
this power tool. Operations for which the power tool was not
designed may create a hazard and cause personal injury.
3. Do not convert this power tool to operate in a way
which is not specifically designed and specified by
the tool manufacturer. Such a conversion may result
in a loss of control and cause serious personal injury.
4. Do not use accessories which are not specifically
designed and specified by the tool manufacturer.
Just because the accessory can be attached to your
power tool, it does not assure safe operation.
5. The rated speed of the accessory must be at least equal to
the maximum speed marked on the power tool. Accessories
running faster than their rated speed can break and fly apart.
6. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
7. The dimensions of the accessory mounting must
fit the dimensions of the mounting hardware of the
power tool. Accessories that do not match the mount-
ing hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
Do not use a damaged accessory. Before each use
8.
inspect the accessory such as abrasive wheels for
chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of the
rotating accessory and run the power tool at maxi-
mum no-load speed for one minute. Damaged acces-
sories will normally break apart during this test time.

9. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
flying debris generated by various applications.
The dust mask or respirator must be capable
of filtrating particles generated by the particular
application. Prolonged exposure to high intensity
noise may cause hearing loss.
10. Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
11. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
12. Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
13. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
14. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
15. Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
16. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
17. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
