Circular saw safety warnings

Cutting procedures

DANGER: Keep hands away from cutting

area and the blade. Keep your second hand

on auxiliary handle, or motor housing. If both

hands are holding the saw, they cannot be cut by

the blade.

2. Do not reach underneath the workpiece. The

guard cannot protect you from the blade below the

workpiece.

3. Adjust the cutting depth to the thickness of

the workpiece. Less than a full tooth of the blade

teeth should be visible below the workpiece.

4. Never hold piece being cut in your hands or

across your leg. Secure the workpiece to a

stable platform. It is important to support the

work properly to minimize body exposure, blade

binding, or loss of control.

►Fig.1

5. Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting tool may contact hidden

wiring or its own cord. Contact with a "live" wire

will also make exposed metal parts of the power

tool "live" and could give the operator an electric

shock.

6. When ripping, always use a rip fence or

straight edge guide. This improves the accuracy

of cut and reduces the chance of blade binding.

7. Always use blades with correct size and shape

(diamond versus round) of arbour holes.

Blades that do not match the mounting hardware

of the saw will run eccentrically, causing loss of

control.

8. Never use damaged or incorrect blade wash-

ers or bolt. The blade washers and bolt were

specially designed for your saw, for optimum

performance and safety of operation.

Kickback causes and related warnings

— kickback is a sudden reaction to a pinched, bound

or misaligned saw blade, causing an uncontrolled

saw to lift up and out of the workpiece toward the

operator;

— 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

operator;

— 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

operator.

Kickback is the result of saw misuse and/or incorrect

operating procedures or conditions and can be avoided

by taking proper precautions as given below.

1. Maintain a rm grip with both hands on the

saw and position your arms to resist 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 precautions are taken.

2. When blade is binding, or when interrupting a

cut for any reason, release the trigger and hold

the saw motionless in the material until the

blade comes to a complete stop. Never attempt

to remove the saw from the work or pull the

saw backward while the blade is in motion

or kickback may occur. Investigate and take

corrective actions to eliminate the cause of blade

binding.

3. When restarting a saw in the workpiece, centre

the saw blade in the kerf and check that saw

teeth are not engaged into the material. If saw

blade is binding, it may walk up or kickback from

the workpiece as the saw is restarted.

4. Support large panels to minimise the risk of

blade 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.

5. Do not use dull or damaged blades.

Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade

binding and kickback.

6. Blade depth and bevel adjusting locking levers

must be tight and secure before making cut. If

bladeadjustmentshiftswhilecutting,itmaycause

binding and kickback.

7. Use extra caution when sawing into existing

walls or other blind areas. The protruding blade

maycutobjectsthatcancausekickback.

8. ALWAYS hold the tool rmly with both hands.

NEVER place your hand, leg or any part of your

body under the tool base or behind the saw,

especially when making cross-cuts. If kickback

occurs,thesawcouldeasilyjumpbackwardsover

yourhand,leadingtoseriouspersonalinjury.

►Fig.4

9. Never force the saw. Push the saw forward at a

speed so that the blade cuts without slowing.

Forcing the saw can cause uneven cuts, loss of

accuracy, and possible kickback.

Guard function

1. Check guard for proper closing before each

use. Do not operate the saw if guard does not

move freely and enclose the blade instantly.

Never clamp or tie the guard so that the blade

is exposed. If saw is accidentally dropped, guard

may be bent. Check to make sure that guard

moves freely and does not touch the blade or any

other part, in all angles and depths of cut.

2. Check the operation and condition of the

guard return spring. If the guard and the spring

are not operating properly, they must be ser-

viced before use. Guard may operate sluggishly

due to damaged parts, gummy deposits, or a

build-up of debris.

3. Assure that the base plate of the saw will not

shift while performing the “plunge cut” when

the blade bevel setting is not at 90 °. Blade

shifting sideways will cause binding and likely kick

back.
