INTRODUCTION

DOUBLE INSULATION is a concept in safety, in electric power tools, which eliminates the need for the usual three

wire grounded power cord and grounded supply system_

Wherever there is electric current in the tool there are two complete sets of insulation to protect the user_ All exposed

metal parts are isolated from internal metal motor compo - nents with protecting insulation.

FEATURES

Features include easily operated bevel cut and depth of cut adjustment mechanisms; positive 0° bevel stop; directed air

flow for keeping line of cut clear; blade wrench storage; and lock-off switch, See Figure 1_

Before attempting to use your saw, familiarize yourself

with all operating features and safety requirements.

SWITCH

Your saw is equipped with a "lock-off" switch, which reduces the possibility of accidental starting. You must depress the

button on top of the handle in order to be able to pull the switch

trigger. The lock resets each time the trigger is released.

APPLICATIONS (Use only for the purpose listed below)

1_ Cutting all types of wood products (lumber, plywood, /

paneling).

ELECTRICAL CONNECTION Your circular saw 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 voltage drop of more than 10 percent will cause a loss of power and overheating. If your saw does not operate when plugged into an outlet, double-

check the power supply.
