 • 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.
