English

cutting edges are less likely to bind and are

easier to control.

g) Use the power tool, accessories and

tool bits etc., in accordance with these

instructions taking into account the

working conditions and the work to

be performed. Use of the power tool for

operations different from those intended

could result in a hazardous situation.

5) SERVICE

a) 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.

ADDITIONAL SPECIFIC SAFETY RULES

FOR CIRCULAR SAWS

Safety Instructions for All Saws

a) 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.

b) Do not reach underneath the workpiece. The

guard cannot protect you from the blade below

the workpiece.

c) 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.

d) 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.

e) Hold power tool by insulated gripping

surfaces 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

shock the operator.

f) When ripping, always use a rip fence or

straight edge guide. This improves the

accuracy of cut and reduces the chance of

blade binding.

g) 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.

h) Never use damaged or incorrect blade

washers or bolt. The blade washers and

bolt were specially designed for your saw, 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 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:

a) 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.

b) 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.

c) 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.

d) 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.

e) Do not use dull or damaged blades.

Unsharpened or improperly set blades produce

narrow kerf causing excessive friction, blade

binding and kickback.
