Model T28523 (Mfd. Since 05/19)

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  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 ...........................16 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 grounding 
plug. Only insert plug into a matching receptacle 
(outlet) that is properly installed and grounded in 
accordance with all local codes and ordinances. 
DO NOT modify the provided plug!
