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.
