Extension Cords

Grounding Requirements

Improper connection of the equipment-grounding

wire can result in a risk of electric shock. The

wire with green insulation (with or without

yellow stripes) is the equipment-grounding

wire. If repair or replacement of the power cord

is necessary, do not connect the equipment-

grounding wire to a live (current carrying)

terminal.

Check with an electrician or qualified service

personnel if you do not understand these

grounding requirements, or if you are in doubt

about whether the machine is properly grounded.

If you ever notice that a cord is damaged or

worn, disconnect it from power, and immediately

replace it with a new one.

The power cord and plug specified under Circuit

Requirements section on the previous page has

an equipment-grounding wire and a grounding

prong. The plug must only be inserted into a

matching receptacle (outlet) that is properly

installed and grounded in accordance with all

local codes and ordinances (see Figure 10).

We do not recommend using an extension cord

with this machine. If you must use an extension

cord, only use it if absolutely necessary and only

on a temporary basis.

Extension cords cause voltage drop, which may

damage electrical components and shorten motor

life. Voltage drop increases as the extension cord

size gets longer and the gauge size get smaller

(higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine

must contain a ground wire, match the required

plug and receptacle, and meet the following

requirements:

Minimum Gauge Size ............................... 12 AWG

Maximum Length (Shorter is Better) ........... 50 ft.

This machine must be grounded! In the event

of certain types of malfunctions or breakdowns,

grounding provides a path of least resistance

for electric current in order to reduce the risk of

electric shock.
