Grounding & Plug Requirements
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.
This machine is equipped with a power cord that has an
equipment-grounding wire and a grounding plug (similar to
the figure on the right). 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.
Serious injury could occur if you con-
nect 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 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.
Extension Cords
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 requirements:
Minimum Gauge Size ................................. 14 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. Instead, have
a qualified electrician install the
proper receptacle on a power supply
circuit that is grounded and meets the
requirements for this machine.
