WARNING: When using electric snow throwers, basic safety precautions should always be
followed to reduce the risk of fire, electric shock, and personal injury. These basic

precautions include the following.

READ ALL INSTRUCTIONS

DoubleInsulatedSnowThrower

2

Double insulation is a concept in the safety of electric snow throwers, which eliminates the need for the usual

three-wire grounded power cord and grounded power supply system. Wherever there is electric current in the

snow thrower, there are two complete sets of insulation to protect the user. All exposed metal parts are isolated

from the internal metal motor components with protecting insulation.

Servicing of a snow thrower with double insulation requires extreme care and knowledge of the system and
should be performed only by a qualified service technician. For repair service we suggest you take the snow

thrower to your nearest authorized service dealer. Always use original equipment manufacturer's (OEM)

replacement parts when servicing.
