work place tamper-proof by installing locks on the doors and on the master switches. Always remove
the lock-off button from the tool and store it in a secure place, when the tool is not in use.
6. NEVER FORCE THE TOOL. It will do the job better and more safely if it is operated at the rate for
which it was designed.

was not designed.

EYE INJURY. Ordinary eyeglasses do not provide adequate protection because the lenses are not
made of safety glass. Also, use a face mask for additional safety and wear a dust mask if the cutting
operation produces dust.
