Grounding.Requirements
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 to travel—in
order to reduce the risk of electric shock.
Improper connection of the equipment-grounding wire will
increase the risk of electric shock. The wire with green
insulation (with/without yellow stripes) is the equipment-
grounding wire. If repair or replacement of the power
cord or plug is necessary, do not connect the equipment-
grounding wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel
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, disconnect it from power, and
immediately replace it with a new one.
For.240V.Connection
This machine is equipped with a power cord that has an
equipment-grounding wire and NEMA 6-20 grounding plug.
The plug must only be inserted into a matching receptacle
(see Figure) that is properly installed and grounded in
accordance with local codes and ordinances.
Extension.Cords
We do not recommend using an extension cord with
this machine. Extension cords cause voltage drop, which
may damage electrical components and shorten motor
life. Voltage drop increases with longer extension cords
and smaller gauge sizes (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.at.240V....................... 12.AWG
Maximum.Length.(Shorter.is.Better).................50.ft.
Model W1687 (For Machines Mfg. Since 9/11)
The machine must be properly set up
before it is safe to operate. DO NOT
connect this machine to the power
source until instructed to do later in
this manual.

No adapter should be used with the
required plug. If the plug does not fit
the available receptacle, or the machine
must be reconnected to a different
type of circuit, the reconnection must
be made by an electrician or qualified
service personnel and it must comply
with all local codes and ordinances.
