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 a 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.
1

■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.
SHEET SANDER SAFETY WARNINGS
■Always wear safety goggles and a dust mask.
■A suitable breathing respirator must be worn while
sanding lead paint, some woods and metal to avoid
breathing the harmful/toxic dust or air. Contact with
or inhalation of dust produced from these materials can
endanger the health of operator and bystanders.
■Do not throw sanding dust on an open fire because
materials in fine particle form may be explosive.
■The product is not suitable for wet sanding.
■When not in use, all tools should be disconnected from
power source.
■Caution, fire hazard! Avoid overheating the object being
sanded as well as the sander. Always empty the dust
collector before taking breaks.
■Clamp workpiece with a clamping device.
Unclamped workpieces can cause severe injury and
damage. Do not hold the material you are sanding by
hand.
■Do not apply excessive pressure to the product.
■Do not use sanding paper larger than needed. Extra
paper extending beyond the sanding pad can also
cause serious lacerations.
■The dust collection box shall be equipped with the
tool. It should be emptied frequently. To connect dust
collection box, insert the adapter of dust box to the dust-
collection opening on the rear end of the sander.
■The product will restart automatically if stalled. Switch
off the product immediately if it stalls. Do not switch
on the product again while it is still stalled, as doing
so could trigger a sudden recoil with a high reactive
force. Determine why the product stalled and rectify
this, paying heed to the safety instructions.
WARNING
Do not throw sanding dust into an open fire because
materials in fine particle form may be explosive.
WARNING
A suitable breathing respirator must be worn while
sanding lead paint, some woods and metal to avoid
breathing the harmful/toxic dust or air.
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.
Materials containing asbestos should only be worked on
or processed by qualified specialist operators.
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
–Using the product will produce considerable amount
of dust and fine particles. Use the dust collection
device or connect a dust extraction vacuum when
operating the product. Wear dust masks containing
filters appropriate to the materials being worked on.
Ensure adequate workplace ventilation. Do not eat,
drink, or smoke in the work area.
■Injury caused by noise and vibration
–Wear ear protection during the sanding operation.
Do not operate the product for long periods of time.
See “Risk reduction”.
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 unit 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.
2

■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.

SANDPAPER SELECTION
Selecting the correct size, grit and type of sand paper is an
extremely important step in achieving a high quality sanded
finish. Aluminum oxide, silicon carbide, and other synthetic
abrasives are best for power sanding. Natural abrasives,
such as flint and garnet are too soft for economical use in
power sanding.
In general, coarse grit will remove the most material
and finer grit will produce the best finish in all sanding
operations. The condition of the surface to be sanded will
determine which grit will do the job. If the surface is rough,
start with a coarse grit and sand until the surface is uniform.
Medium grit may then be used to remove scratches left
by the coarser grit and finer grit used for finishing of the
surface. Always continue sanding with each grit until
surface is uniform.
WARNING
Do not use sander without sandpaper; doing so will
damage the cushion.

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.
