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 in order to reduce the risk of
electric shock.

5-15 RECEPTACLE
Figure 1. NEMA 5-15 plug and receptacle.
DO NOT modify the
included plug or use an
adapter if it 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.
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.
Extension Cords
Minimum Gauge Size ............................14 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:

Figure 2. NEMA 6-15 plug and receptacle.
For 110V operation
: 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.
For 220V operation:
Use the plug type listed in
the Circuit Requirements for this voltage. The
listed plug (similar to the following figure) has
an equipment-grounding wire to safely ground
the machine. 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.
