Grounding Requirements
Extension Cords
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.

NEMA 5-20 plug & receptacle.
This machine is equipped with a power cord that has an
equipment-grounding wire and NEMA 6-15 grounding plug.
The plug must only be inserted into a matching receptacle
(see
Figure 2
) that is properly installed and grounded in
accordance with local codes and ordinances.
For 220V Connection (Prewired)
A NEMA 5-20 plug has a grounding prong that must be
attached to the equipment-grounding wire inside the
included power cord. The plug must only be inserted
into a matching receptacle (see
Figure 3
) that is properly
installed and grounded in accordance with all local codes
and ordinances.
For 110V Connection (Must be Rewired)
The machine must be properly set up
before it is safe to operate. DO NOT
connect to the power source until
instructed to do so later this manual.
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
the gauge 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 for 220V ....................... 14 AWG
Minimum Gauge Size for 110V ....................... 12 AWG
Maximum Length (Shorter is Better) ..................50 ft.
DO NOT modify the provided plug or
use an adapter if the plug will not fit
your receptacle. If the machine must be
reconnected for use on a different type
of electric circuit, the reconnection
should be made by qualified service
personnel; and after reconnection,
the machine must comply with all local
codes and ordinances.
