RULES FOR SAFE OPERATION
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 (Figure A & B).If the tool should electrically malfunction
or break down, grounding provides a low 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 & B.

Figure B
WARNING: Electrical cords can be hazardous. Misuse can result in fire or death by electrical
shock. Read carefully and follow all directions.
WARNING: Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified 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 the plug will not fit the outlet, have a proper outlet
installed by a qualified electrician.

WARNING: Only use the socket outlet on the machine for purpose specified in the instruction
manual.
Jobsite receptacles can vary. Check voltage at receptacles on the jobsite for the best voltage supply. 15
amp GFI outlets are not recommended.

RULES FOR SAFE OPERATION
EXTENSION CORDS
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.
The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 10 gauge
cord can carry a higher current than a 12 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 ampere and use the sum to determine the
required minimum wire size.
GUIDELINES FOR USING EXTENSION CORDS
• If you are using an extension cord outdoors, make sure it is marked with the suffix “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 qualified person before using it.
• Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
• Keep away from water. Do not use if wet.
• Inspect thoroughly before each use. DO NOT USE IF DAMAGED.
• Make sure equipment is not running before disconnecting cord.
• FULLY INSERT plug into outlet.
• Do not remove, bend or modify any metal prongs or pins of cord.
• Do not use excessive force to make connections.
• Do not connect a three prong plug to a two-hole cord.
• Avoid overheating. Uncoil cord and do not cover it with any material.
• Do not walk on cord.
• Do not drive, drag or place objects over cord.
• Minimum 12 gauge cord, 50ft maximum length.
• Regularly examine the supply cord for damage, such as cracking or aging. If damage is found, replace
the cord before further use.
• Only replace the supply cord with the type specified in the instruction manual.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE REFERENCE.
WARNING: Electrical cords can be hazardous. Misuse can result in fire or death by electrical
shock. Read carefully and follow all directions.
WARNING: Do not allow the rotating plates to come into contact with the supply cord.

injury or illness, such as respiratory disease, cancer, birth defects or other
reproductive harm. If you are unfamiliar with the risks associated with the particular
material being cut, review the material safety data sheet and/or consult your
employer, the material manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources of hazardous materials. California and some other other
authorities, for instance, have published lists of substances known to cause cancer, reproductive
toxicity, or other harmful effects. Control dust, mist and fumes at the source where possible. In this
regard use good work practices and follow the recommendations of the manufacturer/supplier,
OSHA/NIOSH, and occupational and trade associations. When the hazards from inhalation of dust,
mists and fumes cannot be eliminated, the operator and any bystanders should always wear a
respirator approved by OSHA/MSHA for the material being cut.
