Model G0622 (Mfg 2/08+)
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.
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 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, and meet the following require-
ments:
Minimum Gauge Size ...........................14 AWG
Maximum Length (Shorter is Better).......50 ft.

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.
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.
This machine is equipped with a power cord that 
has an equipment-grounding wire and a ground-
ing 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.
