an 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.

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.

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.
