of parts and any other condition that may affect the

power tool’s operation. If damaged, have the power

tool repaired before use. Many accidents are caused

by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp 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 dierent

from those intended could result in a hazardous situation.

h) Keep handles and grasping surfaces dry, clean and

free from oil and grease. Slippery handles and

grasping surfaces do not allow for safe handling and

control of the tool in unexpected situations.

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.

SAFETY WARNINGS FOR CIRCULAR SAWS

1) CUTTING PROCEDURES

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 can not 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 the workpiece 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 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.

f) When ripping always use a parallel guide 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.

2) 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 towards operator

• Kickback is the result of tool 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 backwards while the

blade is in motion or kickback may occur. Investigate

and take corrective actions to eliminate the cause of

blade binding. Avoid cutting nails or screws.

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.

f) 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.

g) Use extra caution when sawing into existing walls or

other blind areas. The protruding blade may cut objects

that can cause kickback.

3) LOWER GUARD FUNCTION

a) Check lower guard for proper closing before each

use. Do not operate the saw if lower guard does not

move freely and close instantly. Never clamp or tie

the lower guard into the open position. If saw is

accidentally dropped, lower guard may be bent.

Disconnect the plug, raise the lower guard with the

retracting handle and make sure it moves freely and does

not touch the blade or any other part, in all angles and

depths of cut.

b) Check the operation of the lower guard spring. If the

guard and the spring are not operating properly,

they must be serviced before use. Lower guard may

operate sluggishly due to damaged parts, gummy

deposits, or a build-up of debris.

c) Lower guard should be retracted manually only for

special cuts such as plunge cuts and compound

cuts. Raise lower guard by retracting handle and as

soon as blade enters the material, the lower guard

must be released. For all other sawing, the lower guard

should operate automatically.
