does

not

fit,

contact

a

qualified

electrician

to

install

a

polarized

outlet.

Do

not

change

the

plug

in

any

way.

Double

insulation

eliminates

the

need

for

a

three

wire

grounded

power

cord

and

grounded

power

supply

system.

4.

Grounded

tools

must

be

plugged

into

an

outlet

that

is

properly

installed

and

grounded

in

6.

When

operating

a

power

tool

outside,

use

an

outdoor

extension

cord

marked

"W-A"

or

"W".

These

cords

are

rated

for

outdoor

use

and

reduce

the

risk

of

electric

shock.

Use

in

conjunction

with

a

Ground

Fault

Circuit

Interrupter

(GFCI).

If

operating

a

power

tool

in

a

damp

location

is

unavoidable,

the

use

of

a

GFCI

reduces

the

risk

of

electric

shock.

It

is

recommended

that

the

GFCI

should

have

a

rated

residual

current

of

30

mA

or

less.

7.

Avoid

using

an

unnecessarily

long

extension

cord.

Choose

a

cord

that

is

appropriate

for

the

situation,

as

a

cord

that

is

too

long

and

running

across

the

floor

can

be

more

dangerous

than

helpful.

Using

a

cord

that

is

too

long

or

too

thin

could

damage

the

tool.

Unroll

the

cord

completely

to

KICKBACK

PRECAUTIONS

Kickback

is

a

sudden

reaction

to

a

pinched,

bound

or

misaligned

disc,

causing

an

uncontrolled

tool

to

lift

up

and

out

of

the

workpiece

toward

the

operator;

-

when

the

disc

is

pinched

or

bound

tightly

by

the

workpiece

closing

down,

the

disc

stalls

and

the

motor

reaction

drives

the

tool

rapidly

back

toward

the

operator.

Kickback

may

result

in

loss

of

control

of

the

tool

leading

to

serious

personal

injury

and

I

or

damage

to

the

workpiece

and

I

or

tool.

Kickback

can

be

avoided

by

taking

proper

precautions:

1.

Maintain

a

firm

grip

on

the

tool

and

position

your

body

and

arms

to

allow

you

to

resist

kickback

forces.

Kickback

will

propel

the

tool

in

the

direction

opposite

to

the

wheel's

movement

at

the

time

of

snagging.

2.

Never

place

your

hand

near

the

disc.

If

kickback

occurs,

the

disc

may

pass

over

your

hand

and

seriously

injury

you.

Use

clamps

or

a

vice

to

hold

down

the

workpiece.

3.

Use

special

care

when

working

on

corners,

sharp

edges

etc.

Corners,

sharp

edges

or

bouncing

have

a

tendency

to

snag

the

disc

and

cause

loss

of

control

or

kickback.

4.

When

the

disc

is

binding,

or

when

interrupting

a

cut

for

any

reason,

release

the

trigger

and

hold

the

tool

motionless

in

the

material

until

the

tool

comes

to

a

complete

stop.

Never

attempt

to

remove

the

tool

from

the

workpiece

or

pull

the

tool

backward

while

the

disc

is

in

motion

or

kickback

may

occur.

Investigate

and

take

corrective

actions

to

eliminate

the

cause

of

disc

binding.

5.

When

restarting

a

tool

in

the

workpiece,

center

the

disc

in

the

cut

and

check

that

the

disc

is

not

engaged

into

the

material.

6.

Support

large

panels

to

minimize

the

risk

of

disc

pinching

and

kickback.

Large

panels

tend

to

sag

under

their

own

weight.

Supports

must

be

placed

under

the

panel

on

both

sides,

near

the

line

of

cut

and

near

the

edge

of

the

panel.

7.

To

minimize

the

risk

of

disc

pinching

and

kickback,

when

cutting

operation

requires

the

resting

of

the

tool

on

the

workpiece,

the

tool

should

be

rested

on

the

larger

portion

and

the

smaller

piece

cut

off.

8.

Use

extra

caution

when

making

a

"plunge

cut"

into

existing

walls

or

other

blind

areas.

The

protruding

disc

may

cut

objects

that

can

cause

kickback.

9.

Only

use

discs

designed

for

tool.

Do

not

use

dull

or

damaged

discs.

Unsharpened

or

improperly

set

discs

produce

narrow

cut

causing

excessive

friction,

disc

binding

and

kickback.

Keep

discs

sharp

and

clean.

Gum

and

wood

pitch

hardened

on

blades

slows

the

tool

and

increases

potential

for

kickback.

10.

Never

force

the

tool.

Forcing

the

tool

can

cause

uneven

cuts,

loss

of

accuracy,

and

possible

kickback.

Push

the

tool

forward

at

a

speed

so

that

the

disc

cuts

without

slowing.
