GENERAL POWER TOOL SAFETY WARNING
WARNING Read all safety warnings, instructions, illustrations and
specications provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, re 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.
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the
presence of ammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) ELECTRICAL SAFETY
a) 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.

c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
f) 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.
g) 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.
h) 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..
4) POWER TOOL USE AND CARE
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.

ADDITIONAL SAFETY WARNINGS FOR CONSTRUCTION DUST
The updated Control of Substances Hazardous to Health Regulations 1st October
2012 now also targets to reduce the risks associated with silica, wood and gypsum
dusts.
98

Construction workers are one of the at-risk groups within this because of the dust that
they breathe: silica dust is not just a nuisance; it is a real risk to your lungs!
Silica is a natural mineral present in large amounts in things like sand, sandstone and
granite. It is also commonly found in many construction materials such as concrete and
mortar. The silica is broken into very ne dust (also known as Respirable Crystalline
Silica or RCS) during many common tasks such as cutting, drilling and grinding.
Breathing in very ne particles of crystalline silica can lead to the development of:
• lung cancer
• Silicosis
• Chronic obstructive pulmonary disease (COPD).
And breathing in ne particles of wood dust can lead to the development of Asthma.
The risk of lung disease is linked to people who regularly breathe construction dust
over a period of time, not on the odd occasion.
To protect the lung, the COSHH Regulations sets a limit on the amount of these dusts
that you can breathe (called a Workplace Exposure Limit or WEL) when averaged over
a normal working day. These limits are not a large amount of dust: when compared to
a penny it is tiny – like a small pinch of salt:
This limit is the legal maximum; the most you can breathe after the right controls have
been used.
How to reduce the amount of dust?
1. Reduce the amount of cutting by using the best sizes of building products.
2. Use a less powerful tool e.g. a block cutter instead of angle grinder.
3. Using a different method of work altogether – e.g. using a nail gun to direct fasten
cable trays instead of drilling holes rst.
Please always work with approved safety equipment, such as those dust masks that
specially designed to lter out microscopic particles and use the dust extraction facility
at all time.
For more information please see the HSE website:
http://www.hse.gov.uk/construction or http://www.hse.gov.uk/pubns/cis69.pdf
WARNING! Some dust particles created by power sanding, sawing,
grinding, drill and other construction jobs contain chemicals known
to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks and cement and other masonry products.
• Arsenic and chromium from chemically treated timber.
Your risk from these exposures varies, depending upon how often you do
this type of work. To reduce your exposure to these dusts:
• Work in a well-ventilated.
• Work with approved protective equipment, such as those dust masks
that are specially designed to lter microscopic particles.
VIBRATION
The European Physical Agents (Vibration) Directive has been brought in to help reduce
hand arm vibration syndrome injuries to power tool users. The directive requires power
tool manufacturers and suppliers to provide indicative vibration test results to enable
users to make informed decisions as to the period of time a power tool can be used
safely on a daily basis and the choice of tool.
SEE TECHNICAL SPECIFICATIONS IN THE INSTRUCTION MANUAL FOR THE
VIBRATION LEVELS OF YOUR TOOL.
The declared vibration emission value should be used as a minimum level and should
be used with the current guidance on vibration.
Calculating the actual period of use can be difcult and the HSE website has further
information.
The declared vibration total value has been measured in accordance with EN 62841-1
and EN 62841-2-4 and may be used for compare one tool with another.
The declared vibration total value may also be used in a preliminary assessment of
exposure.

02 Sanding paper (Fig. A)
Always remove dust and chips from the sanding base plate (5) before
attaching sanding paper (9) to reduce the wear of sanding base plate and
sanding paper.
Choosing the right sanding paper
Sanding paper is available with different grain sizes (grit) and for different materials.
The grain size is indicated with a number on the reverse of the sanding paper, the
higher the number, the ner the grain size.
Grain size Class Application
< 80 Coarse Removal of paint and varnish, preparation of rough
surfaces.
80-120 Medium For face sanding and smoothing small irregularities.
>180 Fine Finishing, cleaning plaster and water stain from wood.
• Only use suitable sanding papers in terms of application and size. Do not use
papers that are bigger than the base plate of the product.
• Replace worn or damaged sanding papers immediately.
• Start with a coarse sanding paper and nish with a ne-grained one to achieve a
satisfactory result.
• Do not use the same sanding paper on different materials, e. g. do not use the
sanding paper that has been used for sanding metal to sand wood. Small metal
particles remaining in the sanding paper will lead to scratches.
• We recommend using sanding papers with a hole pattern for sufcient dust
extraction.
Changing/attaching sanding paper with hook-and-loop system
1. With the hook-and-loop system, sanding paper is simply removed by pulling off.
2. Align the hole pattern of the new sanding paper (9) with the one in the base plate
(5) to ensure efcient dust extraction if available.
3. With the hook-and-loop system, sanding paper is simply pressed on the base
plate.

Operation
WARNING! Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists. Use a dust extraction
system suitable for the material as far as possible.
01 Sanding
• Do not use the same sanding paper on different materials, e. g. do not use the
sanding paper that has been used for sanding metal to sand wood. Small metal
particles remaining in the sanding paper will lead to scratches.
• Ensure the workpiece is free of obstacles like nails or screws before operation.
Remove them if required. Where possible, secure smaller workpieces to prevent
them from moving under the product.
• Hold the product with one hand on the hand grip (2) rmly and with the other hand
on the housing.
• Switch the product on and wait until it runs at full speed before placing it on the
workpiece.
• Move the product slowly and steadily over the workpiece surface in parallel and
overlapping stokes.
• Only apply the least possible pressure to keep the product at on the workpiece.
Higher pressure will not increase but lower the performance of the product,
increase wear of the sanding paper and lead to uneven results.
• Work with a dust extraction system particularly when sanding coats of varnish as
the varnish could melt and smear the surface of the workpiece and the sanding
paper.
• Keep the product moving at all times, do not stop in one position to avoid grooves.
• Lift the product from the workpiece before switching it off.
After use
• Switch the product off, wait for complete stop, disconnect it from the power supply
and let it cool down.
• Check, clean and store the product as described below.
