DOUBLE INSULATION

Double insulation is a concept in safety, replacing the
standard grounded supply system, in electric power

tools. The construction of a double insulated tool of-

fers protection equal to,a properly grounded tool with-
our the necessity for us,ng a gruunded conductor, The

double insulation system ehmmntes the need for the
usual three wire 9rounded power cord and grounded

supply system.

Wherever there is electric current in the tool there
ore two complete sets of insulation to protect the user.

All exposed metal parts are isolated from the internal
metal motor components with prOtecting insulation.

The lead wires, switch, etc. with their functional in÷

sulution have the added protection of non-conductlve
sleeving or housings to complete the double insulation

system.

WHEN ELECTRIC TOOLS ARE USED ON FIBER-

GLASS berets, sports cars, etc. it has been found
that they are subject to accelerated wear and possi-

ble premature failure, as the fiberglass chips and
gi4ndings ore highly abrasive to bearings, brushes,

commutator, etc. Consequently it is not recom-
mended that this tool be used tar continuous pro-

duction work on any fiberglass material. During
any use on fiberglass it is extremely important that

the tool is €leaned frequently by blowing wlth on
oir jet.

cord will cause some loss of power. To keep this to

a minimum and to prevent overheating and motor
burn-out, use the table below to determine the MIN-
IMUM wire size (A.W.G.) Extension Cord.
