This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
The power cord and plug specified under "Circuit
Requirements for 220V" on the previous page
has an equipment-grounding wire and a ground-
ing 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 below).
Current Carrying Prongs
figure 2. neMA 6-15 plug and receptacle.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
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 or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
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 gets 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 require-
Minimum Gauge Size ...........................14 AWG
Maximum Length (Shorter is better).......50 ft.
