Grounding & Plug Requirements
This machine MUST be grounded. In the
event of certain malfunctions or break-
downs, 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. Only insert plug
into a matching receptacle (outlet) that is
properly installed and grounded in accor-
dance with all local codes and ordinances.
DO NOT modify the provided plug!

SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug provided—if
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.

Improper connection of the equipment-
grounding wire can result in a risk of
electric shock. The wire with green insu-
lation (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 ser-
vice 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, dis-
connect 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
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 ................. 12 AWG
Maximum Length ............................. 50 ft.
