CORDLESS CIRCULAR SAW

SAFETY WARNINGS

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.

Do not reach underneath the workpiece. The

guard cannot protect you from the blade below the

workpiece.

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.

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.

A typical illustration of proper hand support

and workpiece support.

000186

Hold the power tool by insulated gripping

surfaces only, when performing an operation

where the cutting tool may contact hidden

wiring. Contact with a "live" wire will also make

exposed metal parts of the power tool "live" and

could give the operator an electric shock.

When ripping, always use a rip fence or

straight edge guide. This improves the accuracy

of cut and reduces the chance of blade binding.

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.

Never

use

damaged

washers 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

incorrect

blade

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.

Maintain a firm 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

precautions are taken.

When

blade

•

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.

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.

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.
