GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below may result in
electric shock, fire 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.
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 injuries.
■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
tool in unexpected situations.
■Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing 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.
■Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.

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 the switch is dangerous and must be repaired.
■Disconnect the plug from the power source and/
or remove the battery pack, if detachable, 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 and accessories. 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.
■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.
■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.
SERVICE
■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.
MULTI-TOOL SAFETY WARNINGS
■Always hold power tools by insulated gripping surfaces
only. The cutting accessory may contact hidden wiring
or its own cord. Cutting accessory contacting a “live”
wire may make exposed metal parts of the power tool
“live” and could give the operator an electric shock.
■Always wear safety goggles while operating the tool.
Wear a dust mask when dust is produced.
■The product will restart automatically if stalled.
WARNING
Dust from certain paints, coatings, and materials may
cause irritation or allergic reactions. Dust from wood
such as oak, beech, MDF, and others are carcinogenic.
Only qualified specialists should be allowed to use the
product on materials containing asbestos.
WARNING
The product should never be connected to a power
supply when assembling parts, making adjustments,
cleaning, performing maintenance, or when not using
it. Disconnecting the product from the power supply
will prevent accidental starting that could cause serious
injury.
■Keep mains lead clear from the working range of the
power tool. Always lead the cable away and behind
you.
■When working in walls, ceilings or floors, take care to
avoid electric cables and gas or water pipes.
WARNING
Metallic accessories will become hot during use and
could result in skin burns if contacted by the operator.
Wear gloves when changing accessories. Take care
when setting down the tool between operations to
prevent damage or injury.
■Do not use cutting accessories which are damaged,
cracked or do not fit securely to the product.
■Whenever possible, fit the dust collection accessory
provided and connect it to a vacuum device to remove
dust from the work area and help prevent potential
respiratory irritation and damage to the tool.
■The multi-tool creates vibrations which move the
accessory. The vibrations may cause discomfort if the
product is operated for long periods of time. Take a rest
often, especially if you feel discomfort in the arm, wrist,
or fingers. Choose a speed setting which will get the
work completed efficiently. Read the Residual Risks
and Risk Reduction sections for more information on
vibration-related injury.
ADDITIONAL SAFETY WARNINGS
■We recommend the use of a residual current device
with a residual current rating of 30 mA or less.
■Switch the device off immediately if the insertion tool
stalls! Do not switch the device on again while the
insertion tool is stalled, as doing so could trigger a
sudden recoil with a high reactive force. Determine why
the insertion tool stalled and rectify this, paying heed to
the safety instructions.
●The possible causes may be:
–it is tilted in the workpiece to be machined
–it has pierced through the material to be machined
–the power tool is overloaded

RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the fingers, 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 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 doctor about
these symptoms.
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.
OPERATION
The product is supplied with an extra adapter for use with
other brands of cutting, scraping, and sanding accessories.
Do not use the adapter with the latest generation of RYOBI
accessories supplied with your tool. For example, use
the adapter with the letters “R&F” facing outwards if you
wish to use earlier generation RYOBI, RIDGID or AEG
accessories. The adapter may be turned over for use with
other brands of accessories.
■Secure workpieces that can move with a clamp
to prevent movement during sanding or cutting
operations. Do not hold the workpiece by hand. An
inadvertent slip while operating the product may cause
serious personal injury.
■When making a plunge cut into soft materials like wood
and plasterboard using the cutting accessory, gradually
bring the vibrating blade to the workpiece. Do not push
the vibrating blade hard into the material to be cut. Let
the product do the work and concentrate on keeping the
product and the cutting accessory stable in the position
you wish to make the cut.
■Use the depth/ height gauge to help set your depth of
cut or prevent cutting too deeply into the material.
■Take extra care when cutting non-ferrous metals. The
vibrating cutting accessory may skip around before
beginning the cut. If necessary, drill some holes along
the line to be cut before you start cutting.
■If the cutting accessories become jammed in the
workpiece, switch off the product and disconnect from
the power supply. If the cutting accessory cannot
be removed easily, allow the cutting accessories to
adequately cool before releasing the cutting accessory
from the product. Wear gloves and use hand tools, such
as pliers or wrench, to remove the cutting accessory
from the workpiece.

VIBRATION LEVEL
WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of
exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used
for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may
significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working
period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation of work patterns.
