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 can
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
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size (G1066R/Z) ......12 AWG
Minimum Gauge Size (G1079R) ..........14 AWG
Maximum Length (Shorter is Better).......50 ft.
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 nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel 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, discon-
nect it from power, and immediately replace it with
a new one.
Grounding Instructions
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.
The power cord and plug specified under “Circuit
Requirements for 220V” on the previous page
has an equipment-grounding wire and a ground-
ing prong. 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 (see figure below).
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.
