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 in order to reduce the risk of
electric shock.
This machine is equipped with a power cord
that has an equipment-grounding wire and a
grounding plug (similar to the figure below).
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.
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 an electrician or qualified 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.
No adapter should be used with plug. If
plug does not fit available receptacle, or if
machine must be reconnected for use on a
different type of circuit, reconnection must
be performed by an electrician or qualified
service personnel, and it must comply with all
local codes and ordinances.

Grounding Requirements
Extension Cords
Minimum Gauge Size ............................12 AWG
Maximum Length (Shorter is Better) ....50 ft.
We do not recommend using an extension cord
with this machine. If you must use one, 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 listed in the Circuit
Requirements for the applicable voltage, and
meet the following requirements:
