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.
This machine is equipped with a power cord that has an
equipment-grounding wire and a grounding plug. Only
insert plug into a matching receptacle (outlet) that is
properly installed and grounded in accordance with all
local codes and ordinances. DO NOT modify provided plug!

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
