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.

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.

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.

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 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 by the operator,

if proper precautions are taken.

10. 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.

11.

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.

12. 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.

To avoid kickback, do support

board or panel near the cut.

000192

Do not support board or

panel away from the cut.

Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade

binding and kickback.

14. 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.
