SAFETY

GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, ﬁ re and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated

(cordless) power tool.

1) Work area safety 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 ﬂ ammable 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.

Unmodified plugs and matching outlets will

reduce risk of electric shock.

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 electric shock.

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 electric shock.

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 a residual current device (RCD) protected supply.

Use of an RCD reduces the risk of electric shock.

3) Personal safety 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 inﬂ uence of drugs, alcohol or medication.

English

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 personal injuries.

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 finger on the

switch or energising power tools that have the switch on invites accidents.

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 jewellery. Keep your hair, clothing and gloves away from moving parts.

Loose clothes, jewellery 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 designed.

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 users.

e) Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts and any other condition that may aﬀ ect 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 different

from those intended could result in a hazardous situation.

5) Battery tool use and care a) Recharge only with the charger specified

by the manufacturer.

A charger that is suitable for one type of battery

pack may create a risk of ﬁ re when used with another battery pack.

b) Use power tools only with specifically

designated battery packs.

Use of any other battery packs may create a

risk of injury and ﬁ re.

c) When battery pack is not in use, keep it away

from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another.

Shorting the battery terminals together may

cause burns or a ﬁ re.

d) Under abusive conditions, liquid may be

ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

6) Service a) Have your power tool serviced by a

qualiﬁ ed repair person using only identical replacement parts.

This will ensure that the safety of the power tool

is maintained.

English

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

Lead from lead-based paints,

●

Crystalline silica from bricks and cement and other

●

masonry products, and

Arsenic and chromium from chemically-treated

●

lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to ﬁ lter out microscopic particles.

CIRCULAR SAW SAFETY WARNINGS 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 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 the power tool by insulated gripping surfaces

only, 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 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 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 ﬁ rm 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.

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.

English

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.

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.

d) Always observe that the lower guard is covering

the blade before placing saw down on bench or ﬂ oor.

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.

SPECIFIC SAFETY RULES

1. Never touch moving parts.

Never place your hands, ﬁ ngers or other body parts

near the tool’s moving parts.

2. Never operate without all guards in place.

Never operate this tool without all guards or safety

features in place and in proper working order. If maintenance or servicing requires the removal of a guard or safety feature, be sure to replace the guard or safety feature before resuming operation of the tool.

3. Use right tool.

Don’t force small tool or attachment to do the job of a

heavy-duty tool.

Don’t use tool for purpose not intended —for

example— don’t use circular saw for cutting tree limbs or logs.

4. Handle tool correctly.

Do not drop or throw the tool.

5. Deﬁ nitions for symbols.

6. Keep all screws, bolts and covers tightly in place.

Keep all screws, bolts, and plates tightly mounted.

Check their condition periodically.

7. Do not use power tools if the plastic housing or handle is cracked.

Cracks in the tool’s housing or handle can lead to

electric shock. Such tools should not be used until repaired.

8. Blades and accessories must be securely mounted to the tool.

Prevent potential injuries to yourself or others.

Blades, cutting implements and accessories which have been mounted to the tool should be secure and tight.

9. Carefully handle power tools.

Should a power tool be dropped or struck against

hard materials inadvertently, it may be deformed, cracked, or damaged.

10. Do not wipe plastic parts with solvent.

Solvents such as gasoline, thinner benzine, carbon

tetrachloride, and alcohol may damage and crack plastic parts. Do not wipe them with such solvents.

Wipe plastic parts with a soft cloth lightly dampened

with soapy water and dried thoroughly.

11. Keep motor air vent clean.

The tool’s motor air vent must be kept clean so that

air can freely ﬂ ow at all times. Check for dust build-up frequently.

12. NEVER leave tool running unattended. Turn power oﬀ .

Don’t leave tool until it comes to a complete stop.

13. NEVER touch the blade with bare hands after operation.

14. For this mode, the saw blades should be 165 mm.

15. Because the cordless circular saw operates by

battery power, be aware of the fact that it can begin to operate at any time.

16. When working at elevated locations, clear the area of other people and aware of conditions below you.
