RULES FOR SAFE OPERATION

themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident
prevention measures.

SAVE THESE INSTRUCTIONS
DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need
to be grounded.
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 pre-
cautions to avoid electrical shock.
Important: Servicing of a tool with double insulation
requires extreme care and knowledge of the system and
should be performed only by a qualified service
technician. For service, we suggest you return the tool to
your nearest authorized service center for repair. Always
use original factory replacement parts when servicing.
ELECTRICAL CONNECTION
Your tool has a precision built electric motor. It should
be connected to a power supply that is 120 volts, 60
Hz, AC only (normal household current). Do not
operate this tool on direct current (DC). A substantial
voltage drop will cause a loss of power and the motor will
overheat. If your tool does not operate when plugged
into an outlet, double-check the power supply.
