operated (corded) power tool or battery-operated (cordless)

a) Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of flammable

liquids, gases or dust. Power tools create sparks which

may ignite the dust or fumes.

c) Keep children and bystanders away while operating

a power tool. Distractions can cause you to lose control.

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any adapter

plugs with earthed (grounded) power tools.

b) Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric

shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool. Keep

cord away from heat, oil, sharp edges or moving

parts. Damaged or entangled cords increase the risk of

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of a cord

suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location is

unavoidable, use an earth leakage circuit breaker.

Use of an earth leakage circuit breaker reduces the risk

a) Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not

use a power tool while you are tired or under the

influence of drugs, alcohol or medication. A moment

of inattention while operating power tools may result in

serious personal injury.

b) Use personal protective equipment. Always wear

eye protection. Protective equipment such as dust

mask, non-skid safety shoes, hard hat, or hearing

protection used for appropriate conditions will reduce

c) Prevent unintentional starting. Ensure the switch is

in the off-position before connecting to power

source and/or battery pack, picking up or carrying

the tool. Carrying power tools with your nger on the

switch or energising power tools that have the switch on

d) Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to a

rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance

at all times. This enables better control of the power tool

in unexpected situations.

f) Dress properly. Do not wear loose clothing or

jewelry. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewelry or long hair

can be caught in moving parts.

g) If devices are provided for the connection of dust

extraction and collection facilities, ensure these are

connected and properly used. Use of dust collection

can reduce dust-related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tool. Use the correct power

tool for your application. The correct power tool will do

the job better and safer at the rate for which it was

b) Do not use the power tool if the switch does not turn

it on and off. Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or

the battery pack from the power tool before making

any adjustments, changing accessories, or storing

power tools. Such preventive safety measures reduce

the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the power

tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained

e) Maintain power tools. Check for misalignment or

binding of moving parts, breakage 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 be8

performed. Use of the power tool for operations dierent

from those intended could result in a hazardous situation.

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 CUTTING PROCEDURES

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 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.

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

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

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

g) Use extra caution when sawing into existing walls or

other blind areas. The protruding blade may cut objects

that can cause kickback.

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

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.

d) Always observe that the lower guard is covering the

blade before placing saw down on bench or floor. An

unprotected, coasting blade will cause the saw to walk

backwards, cutting whatever is in its path. Be aware of the

time it takes for the blade to stop after switch is released.
