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, re and/or serious injury.
Save all warnings and instruction for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
Work area safety
■Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating
a power tool. Distractions can cause you to lose
control.
Electrical safety
■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.
■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.
■Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
■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.
■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.
■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.
Personal safety
■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.
■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 injury.
■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.
■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.
■Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power in
unexpected situations.
■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.
■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.
Power tool use and care
■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.
■Do not use the power tool if the switch does not turn
it on and off.Any power tool that cannot be controlled
with switch is dangerous and must be repaired.
■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.
■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.
■Maintain power tools. Check for misalignment or

2
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.
■Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
■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.
Battery tool use and care
■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.
■Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire
■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 fire.
■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.
Service
■Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that safety of the power tool is maintained.

MAINTENANCE
WARNING
Use only original manufacturer’s replacement parts,
accessories, and attachments. Failure to do so can
cause possible injury, contribute to poor performance,
and may void your warranty.
WARNING
Servicing requires extreme care and knowledge
and should be performed only bya qualified service
technician. For service, bring the product to an
authorised service centre for repair. When servicing, use
only original replacement parts.
■Use gloves when maintaining the cutting means.
■Maintain the product with care. Keep the cutter edge

blades on a flat surface. Apply lightweight machine oil
along the edge of the top blade. Do not apply oil when
the product is running.
BATTERY PROTECTION FEATURES
Ryobi 18V Lithium-Ion batteries are designed with features
that protect the Lithium-Ion cells and maximise battery
life. If the tool stops during use, the following may be the
causes:
■The maximum current draw of the battery has been
exceeded, causing it to automatically stop powering the
tool. Release the trigger to reset the tool and pull the
trigger to resume operation.
■Excessive temperatures will cause the battery to stop
powering the tool. Feel the battery pack; if it is too
warm, allow it to cool down.
If the tool still does not work, recharge the battery.
NOTE: The battery pack indicator LED will not work if the
battery protection feature has caused the battery pack to
stop powering the tool. Release the tool trigger or remove
the battery pack from the tool and the battery pack LED
indicator will resume normal function.
RESIDUAL RISK
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use, and the
operator should pay special attention to avoid the following:
■Injury caused by vibration
–Hold the product by designated handles and restrict
working time and exposure.
■Injury caused by exposure to noise
–Wear hearing protection and limit exposure.
■Injury caused by contact with the blades
–The blade cannot be guarded while cutting. Keep
the blade away from yourself and others. Cover it
with the blade sheath when the product is not in
use.
RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome.
Symptoms may include tingling, numbness and blanching
of the ngers, usually apparent upon exposure to cold.
Hereditary factors, exposure to cold and dampness, diet,
smoking and work practices are all thought to contribute
to the development of the these symptoms. There are
measures that can be taken by the operator to possibly
reduce the effects of vibration:
■Keep your body warm in cold weather. When operating
the product wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
■After each period of operation, exercise to increase
blood circulation.
■Take frequent work breaks. Limit the amount of
exposure per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
WARNING
Injuries may be caused or aggravated, by prolonged use
of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
