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, fi re and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool’’ in the warnings refers to your mains­operated (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 qualifi ed 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

RESIDUAL RISKS

Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise and the operator
should pay special attention to avoid the following:

■ Injury caused by dust

– While using the product, considerable dust and fine

particles will be produced. Use the dust collection
device and connect a dust extraction vacuum
during use.

– Wear eye protection at all times.
– Wear respiratory protection masks containing filters

appropriate to the materials being worked. Ensure
adequate workplace ventilation.

– Do not eat, drink or smoke in the work area.

■ Injury caused by noise and vibration

– Wear ear protection.
– Do not operate the product for long periods of time.

See “Risk reduction”.

■ Risk of electrocution if electric cables are cut

– Always hold the product by designated handles. Do

not touch the cutting blades or metal parts of the
product.

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 fi 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 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.
