DeWalt D28000-XE Instruction Manual page 5

• An extension cord must have adequate wire size (AWG or American Wire
Gauge) for safety. The smaller the gauge number of the wire, the greater the
capacity of the cable, that is 16 gauge has more capacity than 18 gauge. An
undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the total length,
be sure each individual extension contains at least the minimum wire size. The
following table shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.

• Do not use an extension cord unless it is absolutely necessary. Use
of improper extension cord could result in risk of fire, electric shock, or
electrocution.
• 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.
Safety Warnings Common for Grinding, Sanding, Wire Brushing,
& Abrasive Cutting-Off Operations
a) This power tool is intended to function as a grinder, sander, wire brush
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.
b) Operations such as polishing are not recommended to be performed with this
power tool. Operations for which the power tool was not designed may create a
hazard and cause personal injury.

c) Do not use accessories which are not specifically designed and recommended
by the tool manufacturer. Just because the accessory can be attached to your
power tool, it does not assure safe operation.
d) 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.
e) 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.
f) The arbour size of wheels, flanges, backing pads or any other accessory must
properly fit the spindle of the power tool. Accessories with arbour holes that
do not match the mounting hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
g) Do not use a damaged accessory. Before each use 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 maximum no-load speed for one minute. Damaged accessories
will normally break apart during this test time.
h) Wear personal protective equipment. Depending on application, use face
shield, safety goggles or safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron capable of stopping small
abrasive or workpiece fragments. The eye protection must be capable of
stopping flying debris generated by various operations . The dust mask or
respirator must be capable of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
i) 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.
j) Hold power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a "live" wire may make exposed metal parts of
the power tool "live" and shock the operator.
