FOR YOUR SAFETY

To ensure safe operation the three-pin plug supplied must be inserted only into a standard three-pin
power point which is efiectivly earthed through the normal husehold wiring.

Extension cords used with the equipment must be three-core and be correctly wired to provide
connection to earth. Wrongly wired extension cords are a major cause of fatalities.

The fact that the equipment operates satisfactorily does not imply that the power point is earthed and
that the installation is completely safe. For your safety, if in any doubt about the effective earthing of the
power point, consult a qualified electrician.

K

For U.S.A. and Canada models.

f
CAUTION
TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION
CORD. RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO
PREVENT BLADE EXPOSURE.
