ELECTRICAL
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.

DO NOT modify the provided plug or
use an adapter if the plug will not
fit the receptacle. Instead, have an
electrician install the proper receptacle
on a power supply circuit that meets
the requirements for this machine.
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 120V ...................... 16 AWG
Maximum Length (Shorter is Better) ................50 ft.
For 120V Connection
This machine is equipped with a power cord that has an
equipment-grounding
wire and NE M A 5-15 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.
