120 VAC GROUNDING INSTRUCTIONS
This appliance shall be grounded while in use to protect the operator from electric shock. If it should electrically malfunction, grounding provides a path of least resistance  for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and a three-contact grounding-type  attachment plug to fit the proper grounding type receptacle. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with  all local codes and ordinances.

WARNING!
The machine must be used with an extension power cord as follows:

• minimum length 15 feet
• type S, or ST, or SO, or STO, or STW
• minimum rate 300V 140/167°F (60/75°C)

DANGER!

• Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as  to whether the outlet is properly grounded.
• Do not modify the plug provided with the appliance. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.
• This appliance is for use on a nominal 120V circuit, and has a grounding plug that looks like the plug (B, Fig. 6). A temporary adapter (B and C) may be used to connect  this plug to a 2-pole receptacle (B), if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet (A) can be  installed by a qualified electrician. The greencolored rigid ear, tab, or the like extending from the adapter must be connected to a permanent ground such as a properly  grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw. Grounding adapters are not approved for use in Canada.
• Replace the plug if the grounding pin is damaged or broken.
• The Green (or Green/Yellow) wire in the cord is the grounding wire. When replacing a plug, this wire must be attached to the grounding pin only.

Extension cords connected to this machine should be 12 gauge, three-wire cords with three-prong plugs and outlets.
DO NOT use extension cords more than 50 feet (15 m) long.
