21. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges

are less likely to bind and are easier to control.

22. Use the power tool, accessories and tool bits

etc. in accordance with these instructions and in

the manner intended for the particular type of

power tool, taking into account the working con-

ditions and the work to be performed. Use of the

ADDITIONAL SAFETY RULES FOR TOOL

DANGER:

Keep hands away from cutting area and the

blade. Keep your second hand on auxiliary han-

dle, or motor housing. If both hands are holding

the tool, they cannot be cut by 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 sta-

ble 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, workpiece

support, and supply cord routing (if applicable).

Hold power tool by insulated gripping surfaces

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 shock the

operator.

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 tool

will run eccentrically, causing loss of control.

Never use damaged or incorrect blade washers

or bolt. The blade washers and bolt were specially

power tool for operations different from those

intended could result in a hazardous situation.

Service

23. Have your power tool serviced by a qualified

repair person using only identical replacement

parts. This will ensure that the safety of the power

tool is maintained.

designed for your tool, for optimum performance

and safety of operation.

Causes and operator prevention of kickback;

•

Kickback is a sudden reaction to a pinched,

bound or misaligned saw blade, causing an

uncontrolled tool 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 rap-

idly 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

workpiece causing the blade to climb out of

the kerf and jump back toward the operator.

Kickback is the result of tool misuse and/or

incorrect operating procedures or conditions

and can be avoided by taking proper precau-

tions as given below.

Maintain a firm grip with both hands on the

tool and position your arms to resist kick-

back forces. Position your body to either

side of the blade, but not in line with the

blade. Kickback could cause the tool to jump

backwards, but kickback forces can be control-

led by the operator, if proper precautions are

taken.

When blade is binding, or when interrupting

a cut for any reason, release the trigger and

hold the tool motionless in the material until

the blade comes to a complete stop. Never

attempt to remove the tool from the work or

pull the tool 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 tool 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 tool is

restarted.
