WARNING

Read all salety

wamings

and all

instruc-

tions. Failure to follow the warnings and instructions

may result in

electric shock, fire and/or serious

injury.

Save all

warnings

and

inskuctions lor futute telerence

The term

"power

tool" in the warnings

refers to

your

mains-operated

(corded)

powertool

or battery-operat-

ed

(cordless)

powertool.

1.1 Work

area

salely

a) Keep work area clean and well

lit.

Cluttered or dark

areas

invite accidents.

b)

Do

not operale

power

tools in explosive

atmos-

pheres,

such as in lhe

presence

ol llammable

liq-

uids,

gases

or dusl.

Power tools

create

sparks which

may ignite the dust or

fumes.

c)

Keep

children

and bystanders away while operal-

ing a

power

tool. Distractions can cause

you

to lose

control.

2.2

ElectriEal

satety

a)

Power lool

plugs

musl match the outlel. Never mod-

ity the

plug

in

any

way. Do nol

use

any adapter

plugs

with earthed

(grounded)

power

lools. Unmodified

plugs

and

matching

outlets

will reduce risk of elec-

tric shock.

b)

Avoid body contact with earthed or

grounded

sur-

faces such as

pipes,

radialors, ranges and relrig-

erators. There is an increased

risk

of electric shock

if

your

body

is eafihed or

grounded.

c) Do not expose

p0wer

l00ls t0 rain

or

wet condilions.

Water entering a

power

tool

will increase the risk

of

electric shock.

d)

Do not

abuse

the

cord.

Never

use lhe cord

for car-

rying,

pulling

or unplugging the

power

tool.

Keep

cord away from heat, oil, sharp

edges

or moving

pads.

Damaged or entangled cords increase the

risk

of electric shock.

I

e)

When

operaling a

power

tool

0uld00rs, use an exlen-

Ell

sion cord suitable for ouldoor use. Use of a cord

suitable for

outdoor use

reduces the risk of

electric

shock.

f) ll operating a

power

lool in a damp location is

unavoidable,

use a

ground

lault

circuit

interupter

(GFCI)

prolected

supply. Use of a GFCI reduces the

risk of electric shock.

2.3 Penonal

salety

a) Stay alert, watch what

you

are doing and use com-

mon

sense when operating a

power

tool. Do not use

a

power

tool while

you

are tired or

under

the influ-

ence

of drugs, alcohol or medication. A moment of

inattention

while operating

power

tools may result in

serious

oersonal

iniurv.

b) Use

perional protictive

equipment. Always wear

eye

protecti0n.

Protective

equipment such as dust

mask,

non-skid safety shoes, hard hat, or hearing

protection

used for appropriate

conditions

will reduce

personal

injuries.

c)

Prevent

unintentional starting. Ensure the

switch

is in the ofFposition

belore connecling lo

power

source and/or battery

pack, picking

up ol

carrying

the tool. Carrying

power

tools with

your

finger

on the

switch

or

energising

power

t00ls

that have the switch

on invites accidents.

d)

Remove

any adjusting key or

wlench

belore turn-

ing the

power

tool on. A wrench or

a

key left

attached

t0 a rotating

pafi

of

the

power

tool may result in

per-

sonal injury.

e)

Do

nol overreach. Keep

properfooling

and balance

at

all

times. This

enables better control of the oow-

er tool in unexoected situations.

f) Dress

properly.

Do not wear loose

clolhing or

jew-

ellery. Keep

your

hair, clothing,

and

gloves

away

from moving

pads.

Loose clothes,

jewellery

or

long

hair

can be caught

in

moving

parts.

properly

used. Use of dust col-

lection can reduce dust-related

hazards.

2.4 Power

tool use and

carg

a)

Do nol force the

power

lool.

Use

the correct

power

tool for

your

application.

The

correct

power

tool will

do

the

job

better and safer at the rate for which it was

designed.

b) Do nol use the

powel

lool il

the switch does

not

turn

it

on and off.

Any

power

tool that

cannot

be controlled

with the switch is dangerous and

must

be

repaired.

c) Disconnecl the

lrom lhe

powel

source and/or

lhe batlery

pack

from

the

power

tool

belore

mak-

ing any adjustments, changing accessories, or stor-

ing

power

tools.

Such

preventive

safety

measures

reduce the risk of starting the

power

tool accidentally.

d) Slore

idle

power

tools

out ol

the reach of

children

and do not allow

persons

unfamiliar wilh the

pow-

er

tool or lhese instructions t0

operale

lhe

power

tool.

Power

tools are dangerous

in the hands of

untrained

users.

e) Mainlain

power

lools.

Check

lor

misalignment 0r

binding ol

moving

parts,

breakage of

parts

and any

olhel condition lhat may atfect lhe

power

tool's

oper-

ation.

lf damaged, have lhe

power

tool repaired

before use.

Many

accidents are caused by

poorly

maintained oower tools.

f) Keep

cutting

tools

shary

and clean. Properly main-

tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.

g)

Use the

power

tool,

accessories and lool bits etc.

in accordance with these instructions, taking into

accounl the

working

conditions and the work to be

performed.

Use of the

power

tool for operations dit

ferent from those intended could result in

a

hzardous

situation.

2.5 Service

a) Have

your

power

tool serviced by a

qualified

repair

person

using

only

identical replacement

pafis.

This

will ensure

that the

safety of the

power

tool is main-

tained.

The

c) Adiust lhe cutling

depth

piece.

Less than

a

full tooth

of

the

blade

teeth

should

be visible below the workoiece.

d) Never hold

piece

being cul

in

your

hands 0r

acloss

your

leg. Secure the workpiece l0 slable

plalform.

It

is

important to support the work

properly

to mini-

mize body exposure,

blade binding, or

loss of

con-

trol.

A typical

illustration of

proper

hand

support,

workpiece

support,

and supply cord

routing

(if

applicable).

g)

Always use blades with conect size and shape

(dia-

mond versus round)

of arbour

holes.

Blades that do

not match the mounting hardware of the saw will run
eccentrically,

causing loss

of control.

h)

Never use damaged or incorrect blade washers or

boll. The blade washers

and

b0lt were

specially

designed

for

your

saw, for optimum

performance

and

safety of operation.

e) Hold

power

lool by

insulaled

gripping

surlaces when

peiloming

an operation where the

cutling

tool may

contact hidden wiring

0r

its

own cord. Contact with

a

"live"

wire will also make exposed metal

parts

of

the

power

tool

"live"

and shock

the

ooerator.

f) When ripping

always use a rip fence

or straight

edge

guide.

This improves the

accuracy of cut and

reduces

the

chance of blade bindino.

a)

Causes and 0perator

Prevention

of Kickback:

-

kickback

is a sudden reaction to

a

pinched,

bound

or misaligned

saw blade, causing an uncontrolled

saw

to lift

uo and out of the workoiece toward the

00eralor:

-

when the

blade is

pinched

or bound tightly by the

kerf closing

down,

the

blade stalls and

the motor

reaction

drives the unit rapidly back toward the oper-

at0r;

-

if the

blade becomes

twisted

or misaligned in the

cut, the teeth

at

the back edge

of

the

blade

can dig

into the top

surface of

the wood

causing

the

blade

to

climb out of the kerf and

jump

back toward the

0peralor.

Kickback is

the result of saw misuse and/or incorrect

operating

procedures

0r conditions

and can

be avoid-

ed

by taking

proper precautions

as

given

below:

1.

Maintain a firm

grip

with both hands

on

lhe saw

and

p0sition y0ur

alms

t0

resisl kickback

forces.

Position

your

body to either side

of

the blade, but

not in line with the blade. Kickback

could cause

the

saw to

jump

backwards, but kickback forces

can be controlled by the operator, if

proper pre-

cautions are taken.

2. When

blade is binding, or when interrupling a

cut lor

any

reason, release

lhe trigger and

hold

the saw motionless in the material until the blade

comes t0 a

complete

stop. Nevel

attempt

to remove

the

saw lrom the

work

or

pull

lhe saw backward

while the blade is in motion

or

kickback may

occur.

Investigate

and

take

corrective actions

to

eliminate the cause 0f blade binding.

3. When restarling a saw in the workpiece, centre

the

saw blade in the

kerl

and check thal saw teeth

are not engaged inlo the material. lf saw

blade

is

binding,

it may walk

up or kickback

f rom the work-

oiece as

the

saw is restafted.

4.

Support

large

panels

to

minimise

the ilsk of

blade

pinching

and

kickback.

Large

panels

tend to

sag

under their own weight.

Supports

must be

placed

under

the

panel

0n both sides, near

the line

of cut

and near the edge of the

panel.

To avoid kickback, do support

board or

panel

near the

cur.

D0 not support board or

panel

away

from

the cut.
