ADDITIONAL SAFETY INSTRUCTIONS FOR
ALL SAWS WITH RIVING KNIFE
a) Use the appropriate riving knife for the blade
being used.
For the riving knife to work, it must be thicker than
the body of the blade but thinner than the tooth
set of the blade.
b) Adjust the riving knife as described in this
instruction manual.
Incorrect spacing, positioning and alignment can
make the riving knife ineffective in preventing
kickback.
c) Always use the riving knife except when plunge
cutting.
Riving knife must be replaced after plunge cutting.
Riving knife causes interference during plunge
cutting and can create kickback.
d) For the riving knife to work, it must be engaged
in the workpiece.
The riving knife is ineffective in preventing
kickback during short cuts.
e) Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
