industrial

tools are made for North

America's

toughest

industrial

and construction

applications. The

design

of every tool in

the line - from

drills to

sanders

to

grinders

-

is

the result

of rigorous

use

on

jobsites

and throughout industry. Each

tool

is

produced

with

painstaking

precision

using advanced manufac-

turing

systems and intense

quality

control.

Every tool is

checked

before it leaves

the factory

to

make

sure it meets

your

standards for

durabiliÿ,

reliabiliÿ

and

power.

WARNING:

When using Electric

Tools, basic safeÿ

precautions

should always

be followed

to reduce the

risk of fire, electric

shock and

personal

injury, including the

following:

*

Read all

lnstructions.

*

KEEP

WORK AREA CLEAN.

Cluttered areas

and benches invite

injuries.

*

CONSIDER

WORKAREA

ENVIRONMENT.

Don't expose

power

tools

to rain.

Don't use

power

tools

in damp or

wet locations.

Keep

work

area

well lit.

*

GUARD

AGAINST ELECTRIC SHOCK.

Prevent body

contact

with

grounded

sufaces.

For example:

pipes,

radiators,

ranges,

refrigerator

enclosures.

*

KEEP CHILDREN

AWAY. All visitors should

be kept away

from

work area.

Do not

let visitors contact tool or extension

cord.

*

STORE

IDLE TOOLS.

When not in use, tools should be stored

in dry,

and

high

or

locked-up

place -

out of

reach of children.

*

DON'T

FORCE

TOOL. lt will do the

job

better and

safer

at

the

rate for which

it was intended.

*

USE

RIGHT

TOOL. Don't

force

small tool or

attachment to do

the

job

of

a

heavy-duty

tool. Don't use tool for

purpose

not

intended, for example,

don't use circular saw

for cutting tree

limbs

or logs.

*

DRESS

PROPERLY.

Do not wear

loose

clothing or

yank

it to dis-

connect

from receptacle.

Keep cord

from

heat, oil and

sharp

CAUTION:

When sawing

electrical

wires may be encountered,

DO

NOT TOUCH ANY

METAL PARTS OF

THE TOOL! Hold the Saw

only by its

plas-

tic

SAVE

THESE

INSTRUCTIONS

Motor

Your DeWalt

tool is

powered

by a DeWalt-built

motor.

Be

sure

your

power

supply

agrees

with nameplate

marking.

120 Volts

AC/DC means

your

saw

will

operate

on alternating

or direct cur-

rent. Lower

voltage

will

cause

loss of

power

and

can

result in

over-heating.

All DeWalt

tools

are

factory-tested;

if this tool does

not operate,

check

the

power

supply.

Double lnsulation

Your

unit

is DOUBLE

INSUI-ATED.

This means that

it is

con-

structed

throughout

with TWO separate

"layers"

of electrical

insu-

lation or one

DOUBLE thickness

of insulation between

you

and

the tool's electrical

system.

Tools

built

with this

insulation system are

not intended to be

grounded.

As a result,

your

tool

is equipped

with

a two-prong

plug

which

permits

you

to

use extension cords

without concern for

maintaining a

ground

connection.

NOTE: DOUBLE

INSULATION does

not take the

place

of

normal

safeÿ

precautions

when

operating

this tool.

This insulation sys-

tem is for

added

protection

againt

injury

resulting

from a

possible

,r{Bctrical

insulation failure within

the tool.

-

l,UTION:

When

servicing

all tools, USE ONLY

IDENTICAL

nEPIâCEMENT

PARTS. Repair or

replace damaged cords.

Electric

Brake

Your saw

has an automatic

electric brake

which is designed

to

stop

the blade

from

coasting

in

about

two seconds after

you

release

the trigger switch.

lt is

useful

when making certain

cuts

in

wood

where a coasting

blade

would result

in a

wide, imprecise

cut.

Occasionally,

under

certain

conditions,

the brake

will not function

properly

and

won't stop

the saw

in the 2 seconds

discussed

above.

lf this condition

persists,

turn the saw

on and off

four or

five times.

lf the brake still

does

not stop the blade

in about

2 sec-

onds,

the

problem

may be

worn brushes.

Replace the brushes as

described

below and

try

the saw again.

lf the

problem

still

per-

sists,

have the tool

seruiced at a

service

center or authorized

ser-

vice facility.

Brushes

DISCONNECT

PLUG

FROM

POWER SUPPLY

lnspect

carbon brushes

regularly by

unplugging

tool,

removing

the'Brush

lnspection Cap

(Figure

2) and

withdrawing

the

brush

assembly.

Keep brushes

clean and

sliding

freely

in their

guides.

Always

replace a used

brush

in the same

orientation

in the

holder

as

it was

prior

to removal.

Carbon

brushes

have

varying symbols

stamped

into their sides, and

if

the

brushes

are

worn down to

the

line closest

to the spring,

they

must be

replaced. Use

only

identi-

cal

DeWalt brushes.

Always

replace

both brushes.

Use

of the

correct

grade

of

brush

is essential

for

proper

operation

of

electric

brakes.

New brush assemblies

are

available

at

your

local service

center.

The tool should

be allowed

to

"run

in"

(run

at

no load with-

out blade)

for 10

minutes before

use to

seat new brushes.

This is

especially

important

for saws equipped

with electric brakes,

which

may

be

erratic

in operation

until the brushes

are

properly

seated

(worn

in).

While

"running

in"

DO NOT

TlE,

TAPE, OR OTHERWISE

LOCK

THE TRIGGER SWITCH

ON.

HOLD

BY HAND ONLY.
