1. SAFETY INSTRUCTIONS
Warning!Read all the safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, re and/or serious injury. Save all the warnings and instructions for future reference.
The term “power tool” listed in all the warnings below refers to your orbit sander tool.
1) Work area
a) Keep the working area clean and well lit. Messy and dark surfaces creates risks of accidents
b) Do not use power tools in potentially explosive areas, for example near ammable liquids, gases or dust
Power tools create sparks that can ignite dust or smoke.
c) Keep children away when using the power tool. Distraction can result in you losing control.
2) Electric safety
a) The cable connection must match the electrical outlet. Never change the outlet in any way. Do not use
adapters with earthed power tools. Unmodied outlets or plugs reduce the risk of an electric shock.
b) Avoid body contact with earthed surfaces such as pipes, radiators and refrigerators. There is an increased
risk of electric shocks if your body is earthed.
c) Do not expose power tools to rain or wet conditions. Water that enters a power tool increases the risk of
electric shock.
d) Do not damage the cord. Never use the cord to carry the power tool. Keep the cord away from heat, oil,
sharp edges or moving parts. Damaged or entangled cables increase the risk of electric shock.
e) Use an extension cord that is suitable for outdoor use when you are using the power tool outside. Use of a
cord that is suitable for outdoor use reduces the risk of electric shocks.
f) If it is unavoidable to use the power tool in a wet condition , use a protected power supply with a residual
current. Usage of a residual current reduces the risk of electric shocks.
3) Personal safety
a) Pay attention, see what you do and use common sense when using the power tool. Do not use the power
tool when you are tired or affected by drugs, alcohol or medications. A moment of inattention when using
the power tool can result in serious injury.
b) Use safety equipment. Always eye protection. Safety equipment such as face mask, protective shoes,
hairnet, hearing protection used under appropriate conditions reduce injuries.
c) Avoid unintentional starts. Make sure the circuit-breaker is off before connecting it to the power source
and/or the battery pack, picks up or carries the tool. Carrying the tool with your nger on the circuit-breaker
or power tools that have the circuit-breaker in the ON-mode can result in accidents.
d) Remove eventual adjustment key or wrench before turning on the tool. A wrench or a key that is left on a
rotating part of the tool can result in personal injury.
e) Do not extend over. Keep the right foot and balance all the time. This enables better control of the power
tool in unexpected situations.
f) Dress properly. Do not use loose clothing or jewelry. Keep your hair, clothes and gloves away from the
moving parts. Loose clothing, jewelry or long hair can get stuck in moving parts.
g) If devices are provided with a connection for a vacuum-clean or collecting systems, make sure that they
are connected and used correctly. Use of these devices can decrease dust-related hazards.

4) Usage of power tools
a) Do not push the power tool. Use the right tool for the area of application. The correct power tool makes the
job better and safer at the pace for which it was designed.
b) Do not use the tool if the circuit-breaker does not turn on and off. A power tool that cannot be regulated
with the circuit-breaker is dangerous and must be repaired.
c) Unplug the power source and/or the battery from the power tool before you do any adjustments or change
accessories. Such preventive safety measures reduce the risk of the tool starting by mistake.
d) Keep the power tool out of reach of children and do not let inexperienced persons use the tool. Power tools
are dangerous in the hand of unskilled users.
e) Take care of power tools. Check that wrong parts are not damaged, such parts can affect the function of
the power tool. If it is damaged, repair the tool before use. Many accidents occur because of poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to pinch and are easier to steer
g) Use the power tool, accessories and tool pieces etc. in accordance with these instructions and in the
manner intended for the type of working conditions and the work to be performed. Using the power tool for
operations that differ from those intended can result in a dangerous situation.
5) Service
a) Have your power tool serviced by a qualied repairer with only identical spare parts. This ensures that the
safety of the power tool is maintained.
2. SAFETY INSTRUCTIONS FOR ALL APPLICATIONS
a) This power tool is intended to work as a sanding tool. Read all the safety instructions, illustrations and
specications that come with this power tool. Failure to follow all instructions may result in electric shock,
re and/or serious injury.
b) Actions such as brushing, polishing or cutting are not recommended with this power tool. Applications for
which the power tool was not designed for can create a hazard and cause personal injury.
c) Do not use accessories that are not specially designed and recommended by the tool manufacturer. Just
because the accessory can be attached to the power tool does not guarantee safe operation
d) The nominal speed of the accessory must be at least equal to the maximum speed marked on the power
tool. Accessories that go faster than their nominal speed can break and y away.
e) The outer diameter and thickness of your accessory must be within the framework of the capacity of your
power tool. Accessories that are not in the correct size cannot be adequately protected or controlled.
f) Threaded mounting of accessories must match the rethreaders. For accessories that are mounted on
anges, the bore hole in the accessory must t the location diameter of the ange. Accessories that do not
match the power tool will be out of balance, vibrate too much and may cause loss of control.
g ) Do not use a damaged accessory. Before each use, inspect the accessory such as sanding pad for
splinters and cracks, back plate for cracks or excessive wear, wire brush for loose or broken threads. If
the power tool or accessory has been dropped, inspect it for damage or replace and install an undamaged
accessory. After inspecting and assembling the accessories, place yourself and employees away from the
rotating tool and run the tool at maximum speed without any load for one minute. Damaged accessories
will normally shatter during this test period.
h) Use protective equipment. Depending on the application, wear a mask or goggles. Wear a suitable dust
mask, hearing protection, gloves and workshop apron that can stop small abrasives or fragments from the
workpiece. The eye protection must be able to stop splinters generated by various operations. The dust
mask or the respirator must be able to lter particles generated by your application. Long-lasting exposure
to high-intensity noise can cause hearing loss.

i) Keep unauthorized persons at a safe distance from the work area. The one who enters the work area must
wear protective equipment. Fragments of the workpiece or broken accessories can y away and cause
damage beyond the immediate area of use.
j) Hold the power tool only in insulated gripping surfaces when performing an application where the cutting
tool may come in contact with hidden wires or it’s own cord. Cutting accessories that come into contact
with an electric cord can make exposed metal parts of the power tool electric and can give the user an
electric shock.
k) Place the power cord out of reach of any rotating accessories. If you lose control, the cord may be cut or
torn and your hand or arm may be pulled into the rotating accessory.
l) Do not put the tool away until it has stopped completely. The rotating accessory can grab the surface and
tear the tool out of your hand.
m) Never leave the tool running while carrying it by your side. In case of accidental contact with the rotating
accessory, clothes can get caught and pull the accessory towards your body.
n) Clean the tool’s air vents regularly. The engine fan draws dust into the housing and excessive accumulation
of powdered metal can cause electrical hazards.
o) Do not use the tool near ammable materials. Sparks can ignite these materials.
p) Do not use accessories that require liquid coolant. Use of water or other liquid coolant may result in electric
shocks.
OTHER SAFETY INSTRUCTIONS FOR ALL APPLICATIONS
Reversal and related warnings
Backlash is a sudden reaction to a pinching or jammed rotating wheel, a brush or any other accessory. Pin-
ching or hanging causes a quick stop of the rotating accessory, which in turn forces the power tool out of
control in the opposite direction.
For example, if a sanding wheel is stuck or pinched by the workpiece, the edge of the wheel entering the
clamping point may dig into the surface of the material, causing jumps or projection of the sanding wheel.
The wheel can jump towards the user and even break under these conditions. Backlash is a result of improper
use of the tool and/or the application or the conditions are incorrect and can be avoided by taking appropriate
precautions such as listed below.
a) Hold the tool and position your body and arm so that you can withstand backlash forces. Always use the
auxiliary handle, where applicable. For maximum control of return or rotation response at start-up. The user
can control the reaction moment or the forces, if the precautions are taken.
b) Never place your hand near the rotating accessory. The accessory can bounce against your hand.
c) Do not place yourself in the area where the power tool is mowing if it should strike back. The rebound can
push the tool in the opposite direction.
d) Be careful when working with corners, sharp edges, etc. Avoid twists and snaps in the accessory. Corners,
edges or sharp turns tend to hang the rotating accessory and cause loss of control or backlash.
ADDITIONAL SAFETY INSTRUCTIONS FOR SANDING
Set specic safety guards for sanding
a) Do not use sandpaper that is too large for the sanding wheel. Follow the manufacturer’s recommendations
when choosing sandpaper. Heavier paper that extends beyond the sanding pad carries a risk of tearing that
can cause a crash, tear of the disc or bounce back.

WARNING SYMBOLS
Warning- to reduce the risk of injury, the user must read the instruction manual.
Always use ear protection
Always use safety goggles
Always use a face mask
In accordance with essential applicable safety standards in European directives
3.1 Machine-realted safety instructions
- Harmful/toxic dust can be produced during your work (e.g lead paint, certain types of wood and metal).
Contact with this dust, especially inhalation of it, can compose a danger to users or people nearby. Follow
the safety regulations that apply in your country. Connect the power tool to a suitable extraction system.
For your own safety, wear a protective face mask.
Always wear safety goggles to protect against the risks of sanding.
Always use a residual current when sanding metal, as well as when you can not avoid using the tool
in wet conditions. In event of an electric shock, the switch protects you against life-threatening
electricity through your body.
- Clean work equipment immersed in oils, such as sanding pads or sanding cloths, with water let dry. Work
equipment soaked in oil can burn spontaneously
- NOTE: Risk of re!
Avoid overheating the sanding material and the sanding tool. Always empty the dust container before
taking a break. Dust in a lter bag or lter in a mobile extraction system can self-ignite underneath
unfavorable conditions such as ying sparks when sanding metals.There is a special danger if the dust is
mixed with paint, polyurethane residues or other chemical material and the sanding material is hot after long
periods of work.
- Always use original sanding pads. Foreign pads are not suitable for the speed of the sanding tool and can
break.
- If the tool drops or falls, check that the machine and the sanding pad are not damaged. Remove the sanding
pad for closer inspection. Repair damaged parts before using it again. Damaged sanding pads and damaged
tools can cause damage and machine instability.

3.2 Mixed dust containing metal and sanded damp surfaces
With mixed dust containing metal (such as dust resulting from car paint ) and when sanding damp surfaces,
the following measures must be followed for safety reasons :
- Install an upstream circuit breaker (GFCI, PRCD)
- Connect the machine to a suitable vacuum cleaner
- Blow out the engine housing regularly to remove dust.
4. Intended use
The sanding tool is designed for sanding wood , plastic, composite, paint/varnish, llers and similar materials
according to the instructions. With mixed dust containing metals (e.g dust resulting from painting in the
automotive industry) and when sanding damp surfaces, special safety instructions must be followed. The
sanding tool is not intended to be suitable for sanding bare metal. Materials containing asbestos cannot be
treated.
The user is responsible for incorrect or unintended use.

The appropriate sanding paper and sanding cloth can be quickly and easily attached to the sanding pad. Press
the self-adhesive sanding tool onto the sanding pad.
With a reduced attached surface of the sanding paper can the sanding pad accessories, especially
those that do not yet touch the workpiece, can come loose from the sanding pad and cause damage.
Replace the sanding pad!
7. Dust extraction
Warning
Dust danger
Dust can be harmful for your health. Always work with a vacuum cleaner.
Always read the applicable national regulations before removing hazardous dust.
The power tool does not have its own extraction unit. At the extraction contact, a mobile vacuum cleaner with
a hose diameter of 27mm can be connected.

Recommendation
Use an antistatic suction hose. This helps to reduce the electrical charge.
