authorized service facility. The conductor with insulation 
having an outer surface that is green with or without yellow 
stripes is the equipment-grounding conductor. If repair 
or replacement of the electric cord or plug is necessary, 
do not connect the equipment-grounding conductor to a 
live terminal. Repair or replace a damaged or worn cord 
immediately. Stay constantly aware of cord location and 
keep it well away from the rotating blade.

 

INSPECT  EXTENSION  CORDS  PERIODICALLY

POLARIZED PLUGS. 

To reduce the risk of electric shock, 

this tool has a polarized plug (one blade is wider than 
the other). This plug will fit in a polarized outlet only one 
way. If the plug does not fit fully in the outlet, reverse the 
plug. If it still does not fit, contact a qualified electrician 
to install the proper outlet. Do not change the plug in any 
way.

hands and fingers for any reason. Always turn the power off.

 

ALWAYS SUPPORT LONG WORKPIECES 

while cutting 

to minimize risk of blade pinching and kickback. Saw may 
slip, walk, or slide while cutting long or heavy boards.

 

ALWAYS USE A CLAMP

 to secure the workpiece when 

possible.

 

BE SURE THE BLADE CLEARS THE WORKPIECE.

END OF A CLAMPED WORKPIECE. NEVER 

hold onto 

or bind the free scrap end of the workpiece in any opera-
tion. If a work clamp and length stop are used together, 
they must both be installed on the same side of the saw 
table to prevent the saw from catching the loose end and 
kicking up.

 

NEVER 

cut  more  than  one  piece  at  a  time. 

DO  NOT 

STACK

 more than one workpiece on the saw table at a 

time.

 

NEVER  PERFORM  ANY  OPERATION  FREEHAND.

 

Always place the workpiece to be cut on the miter table 
and position it firmly against the fence as a backstop. 
Always use the fence.
