CIRCULAR SAW (SKIN ONLY)
CT20VCIRCSWB

Save all warnings and instructions for future reference. The term “power tool” refers to your
mains operated (corded) power tool or battery-operated (cordless) power tool.
Work area
•Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
•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.
•Keep bystanders and children away while operating a power tool. Distractions can
cause you to lose control of the device.
Electrical safety
1. 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 the risk of electric shock.
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor
use to reduce the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a Ground Fault
Circuit Interrupter (GFCI) protected supply to reduce the risk of electric shock.
SAFETY & WARNINGS

Personal safety
1. Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use tool while tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in
serious personal injury.
2. Use personal protective equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat or hearing protection used for
appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the off position before
connecting to a 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.
4. 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.
5. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key
that is left attached to a rotating part of the tool may result in personal injury.
6. Do not overreach. Always keep proper footing and balance. The enables better
control of the power tool in unexpected situations.
7. Only use safety equipment that has been approved by an appropriate standards
agency. Unapproved safety equipment may not provide adequate protection. Eye
protection must be ANSI-approved and breathing protection must be NIOSH-
approved for the specific hazards in the work area.
Power tool use and care
1. Do not force the tool. Use the correct tool for your application. The correct tool will
do the job better and safer at the rate for which it is designed.
2. Do not use the tool if the switch does not turn it on or off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or the battery pack from the power
tool before making any adjustments, changing accessories or storing the tool. Such
preventive safety measures reduce the risk of starting the tool accidentally.
4. Store idle power tools out of the reach of children and other untrained persons.
Power tools are dangerous in the hands of untrained users.
5. Maintain tools with care. 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.
6. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting
edges are less likely to bind and are easier to control.
7. Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used
on another tool.

Battery use and care
1. Ensure the switch is in the off position before inserting the battery pack. Inserting
the battery pack into power tools that have the switch on invites accidents.
2. 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 fire when used with
another battery pack.
3. Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
4. When the 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 fire.
5. If the appliance is misused or damaged, liquid may be ejected from the battery;
avoid contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, seek medical help as well. Liquid ejected from the battery may cause irritation
or burns.
6. If the battery is damaged, vapours may be emitted which can irritate the
respiratory system. Provide fresh air and seek medical help in case of inhalation.
7. Do not open the battery. Keep the battery away from sources of heat, such as fire
or continuous direct sunlight, to avoid the danger of explosion.
Circular saw use and safety
•Always wear safety goggles or eye protection when using this tool. Use a dust mask
or respirator for applications which generate dust. This saw may throw up debris
that could lodge in the eyes causing severe pain or injury.
•Inspect the bolts and blade washers before each use. Damaged bolts or blade
washers can cause injury.
•When using the Circular Saw, always maintain a firm grip on the tool with both
hands. Never put your hands or feet in the cutting area. Do not grasp the tool or
place your hands too close to the blade. Keep your hands well away from the
blade. Never reach underneath the tool while the blade is in motion. Do not use
your legs or feet to stabilise the workpiece.
•Keep the handle of the circular saw dry, clean and free from oil and grease.
•Disconnect battery pack from tool and place the switch in the locked or “Off”
position before making any assembly adjustments, changing accessories,
performing any inspection, maintenance or cleaning procedures. Such preventive
safety measures reduce the risk of starting the tool accidentally which could cause
serious personal injury.
•Be extra careful when cutting in high or hard-to-reach locations. Avoid sawing
overhead. Be on the lookout for hidden wires and falling debris.
•Do not use the circular saw if it has been damaged, left outdoors in the rain, snow,
wet or damp environments or immersed in liquid.
•Maintain labels and nameplates on the tool. These carry important information. If
unreadable or missing, contact Kogan for a replacement.

•Keep your body positioned to either side of the saw blade, but not in line with the
saw blade. Kickback could cause the saw to jump backwards.
•Check the lower guard for proper closing before each use. Do not operate the saw if
the lower guard does not move freely and close instantly. Never clamp or tie the
lower guard into the open position. If the saw is accidentally dropped, the lower
guard may be bent. Raise the lower guard with the retracting lever and make sure it
moves freely and does not touch the blade or any other part, in all angles and
depths of cut.
•Check the operation and condition of the lower guard spring. If the guard and the
spring are not operating properly, they must be serviced before use. The lower
guard may operate sluggishly due to damaged parts, gummy deposits or a build-
up of debris.
•The lower guard should be retracted manually only for special cuts such as “pocket
cuts” and “compound cuts”. Raise the lower guard by the retracting lever. As soon
as the blade enters the material, the lower guard must be released. For all other
sawing, the lower guard should operate automatically.
•Always ensure that the lower guard is covering the blade before placing the saw
down on bench or floor. An unprotected, spinning 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.
•Never hold the piece being cut in your hands or across your leg. It is important to
support the workpiece properly to minimise body exposure, blade binding or loss of
control.
•Hold the tool by the 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 tool “live” and shock the operator.
•When ripping, always use a rip fence or straight edge guide. This improves the
accuracy of the cut and reduces the chance for blade binding.
•Always use blades with correct size and shape (diamond vs. round) arbour holes.
Blades that do not match the mounting hardware of the saw will run erratically,
causing loss of control.
•Always wear eye protection while operating this power tool.
•Always remove the battery pack before assembling and removing the blade. Failure
to remove the battery pack from saw could result in accidental starting, causing
possible serious personal injury.
•A 5-3/8-inch blade is the maximum blade capacity of your saw. Never use a blade
that is too thick to allow outer blade washer to engage with the flats on the spindle.
Larger blades will come into contact with the blade guard, while thicker blades will
prevent the blade screw from securing the blade on a spindle. Either of these
situations could result in a serious accident.
Kogan.com accepts no liability for accidents caused through misuse or not following the
instructions supplied here. Usage of power tools carries the risk of property damage, serious
injury or even death.

Safety instructions for the battery charger
•Before using battery or charger, read all instructions and cautionary markings on
the battery charger, battery pack and product using the battery.
•Use only the charger which accompanied your product or direct replacement. Do
not substitute any other charger. Use only the same supplier approved chargers
with your product.
•Do not disassemble or operate the charger if it has received a sharp blow, been
dropped or otherwise damaged in any way. Incorrect reassembly may result in a
risk of electric shock, electrocution or fire.
•Do not recharge the battery in a damp or wet environment. Do not expose the
charger to rain or snow. If the battery case is cracked or otherwise damaged, do not
insert into charger. Battery may short or fire may result.
•Charge only supplier approved rechargeable batteries. Other types of batteries
may burst and cause personal injury or damage.
•Charge battery pack in temperatures above 0ºC and below 45ºC. Store the tool
and battery pack in locations where temperatures will not exceed 49ºC. This is
important to prevent serious damage to the battery cells.
•Pull by the plug rather than the cord when disconnecting charger or when
disconnecting cords. This will reduce the risk of damage to the electric plug and
cord.
•Make sure that cord is located so that it will not be stepped on, tripped over or
otherwise subjected to damage or stress.
•Do not use an extension cord unless it is necessary. Use of improper extension cord
could result in a risk of fire, electric shock or electrocution.
•Do not operate charger with damaged cords or plugs - have them replaced
immediately.
•Disconnect the charger from the outlet before attempting any cleaning. This will
reduce the risk of electric shock. Removing the battery pack will not reduce this risk.

Safety instructions for the battery pack
•Do not incinerate the battery pack even if it is severely damaged or is completely
worn out. The battery pack can explode in a fire. Toxic fumes and materials are
created when lithium-ion battery packs are burned.
•Do not charge or use the battery in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Inserting or removing the battery from the
charger may ignite the dust or fumes.
•If battery contents come into contact with the skin, immediately wash the area
with mild soap and water. If battery liquid gets into the eye, rinse water over the
open eye for 15 minutes or until irritation ceases. If medical attention is needed, the
battery electrolyte is composed of a mixture of liquid organic carbonates and
lithium salts.
•Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If
symptoms persist, seek medical attention.
•Charge the battery packs only in the charger which accompanied your product.
•Do not splash or immerse in water or other liquids. This may cause premature cell
failure.
•Do not store or use the tool and battery pack in locations where the temperature
may reach or exceed 40°C (such as outside sheds or metal buildings in summer).
•When batteries are not in tool or charger, keep them away from metal objects.
•Do not put batteries into fire or expose to high heat. They may explode.
