SAFETY RULES

WARNING: The double-insulated system is intended to protect the user from shock

resulting from a break in the tool's internal wiring. Observe all normal safety precautions relat-

ed to avoiding electric shock. 

1. Know your machine. Read this manual carefully. Learn the machine’s applications and

limitations, as well as specific potential hazards peculiar to it.

2. Ground all machines. This machine is “Double Insulated,” meaning that all outside metal

parts are insulated from electrical power. Double Insulated tools are equipped with a

polarized plug. 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 a polarized outlet. Do not attempt to circumvent this safety feature.
