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.
General Power Tool Safety Warnings– Work area
safety
•Keep work area clean and well lit. Clutter or dark areas
invite accidents.
•Do not operate power tools in explosive atmosphere,
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.
General Power Tool Safety Warnings– 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.
General Power Tool Safety Warnings– 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.
General Power Tool Safety Warnings– 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.
4 EN
Cordless random orbital sander PESS 10-20V

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.
General Power Tool Safety Warnings– Battery tool
use and care
•Recharge only with charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack.
•Use power tools only with specifically designed battery
packs. Use of any other battery packs may create a risk of
injury and fire.
•When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
•Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.
•Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
•Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
•Follow all charging instructions and do not charge the
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outsides the specified range may damage
the battery and increase the risk of fire.
General Power Tool Safety Warnings– Charger use
and care
•This charger can be used by children aged
from8years and above and persons with reduced
physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given
supervision or instruction concerning use of the

EN 5
Cordless random orbital sander PESS 10-20V
Additional safety warnings for the random orbital
sander
•Only use the power tool for dry sanding. Water entering
an electrical appliance increases the risk of electric shock.
•Make sure that nobody's safety is jeopardized by
flying sparks. Remove combustible materials from the
working environment. Grinding metal causes sparks to
fly.
•Attention, fire hazard! Avoid overheating of the
material to be sanded and the sander. Before taking
work breaks always empty the dust container.
Unfavourable conditions such as flying sparks when
sanding metal render abrasive dust in the dust bag, micro
filter, paper bag (or in the filter bag or filter of the vacuum
cleaner) prone to self-ignition. The risk is particularly high
when the abrasive dust is mixed with residues of paint,
polyurethane or other chemical substances and the
sanding material is hot after a longer period of work.
•Regularly clean the power tool’s air vents. The motor’s
fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
•During operation hold onto the power tool with both
hands. Make sure that you stand firmly on the ground. It is
safer to handle the power tool with two hands.
•Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your
control.
•Secure the workpiece. The grip of tensioning devices or a
vice is more secure than holding the workpiece only by
hand.
•Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
•Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments. The
eye protection must be capable of stopping flying debris
generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
•Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory could
snag your clothing, pulling the accessory into your body.
•Hold the power tool by the insulated gripping surfaces,
as the grinding surface could hit the connecting cable.
Damaging a live wire might energize metal parts of the
power tool and lead to an electric shock.
•Never support your hands next to or in front of the
device and the surface to be processed. There is a risk
of injury if the tool slips.
Additional Safety Warnings for Sanding Operations
•Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
•Do not use worn, torn or heavily contaminated sanding
sheets. Damaged abrasive sanding sheets can be torn
apart, catapulted away and so lead to personal injury.
•For processing wood, or in particular materials that
produce harmful dusts when sanded, connect the
power tool to an appropriate external exhaust system.
•Only hold the power tool against the workpiece when
the tool is switched on and running. If you are finished
with processing the workpiece, lift the power tool off
the workpiece before you switch it off.
•Using a power tool that comes equipped with a dust
collector or can be connected to the vacuum cleaner
by means of a dust extraction device involves a fire
hazard. In unfavourable conditions – e.g. in case of flying
sparks caused by grinding metal or metal remainders in
wood – the wood dust inside the dust collector (or in the
vacuum cleaner's dust collection bag) might self-ignite.
The risk is particularly high when the wood dust is mixed
with paint residues or other chemical substances and the
sanding material is hot after a longer period of work.
Therefore, avoid overheating of the workpiece and of the
power tool at all times and empty the dust collector or the
vacuum cleaner's dust bag before taking work breaks.
•Do not use the dust extraction system when grinding
metals.
•Ensure sufficient ventilation.
•Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when
selecting sanding paper. Larger sanding paper extending
beyond the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc or kickback.

Oscillation rate selection
By use of the setting wheel for oscillation rate selection you can
change the oscillation rate at any time, even during operation of
the device. The required oscillation rate depends on the material
and the operating conditions and can be determined by way of
field-testing. For sanding harder materials such as wood or
metal we recommend a higher oscillation rate, for softer
materials e.g. non-ferrous metals and varnishes a low
oscillation rate is sufficient.
The setting range covers the levels1– 6(6,000– 24,000rpm).
1. Turn the setting wheel(17) to the desired oscillation rate.

Operation
Tips and notes for handling the orbital sander
General information:
• Only use sanding sheets which are approved for the device
used.
• Before every application, make sure that you have selected
the correct sanding sheet for the intended use. A coarse
grit is suited for rough grinding, a fine grain size, on the
other hand, is more appropriate for fine and finish grinding.
• Do not process wood and metal using the same sanding
sheet.
• Only use intact, flawless sanding sheets. Damaged
sanding sheets could tear and cause damage to the
workpiece. Exchange sanding sheets in due time.
• Clamp the workpiece unless it is firmly and safely
positioned by its own weight.
• Do not overload the device so that it comes to a standstill.
• Keep the venting slots clear to prevent the motor from
overheating.
Sanding:
• The oscillation rate and grain size of the sanding sheet
define the removal rate and the surface finish.
• Always sand in parallel to the grinding path ensuring an
appropriate overlap.
• Do not apply excessive contact pressure. Increased
contact pressure leads to a greater wear of the device and
the sanding sheet.
• If the material's surface is untreated, start grinding with
coarse or medium grain size and finish off with a fine grit.
• Best use a coarse grain size (40 or 60 grit) for removing
paint and for rough grinding particularly raw wood. For
surface-grinding undressed or sawn timber use abrasive
belts of medium grit (grain size80, 100 or 120). Use a fine
grit (grain size180, 240 or 320) to smoothen and fine-
grind timber and surfaces coated with old paint as well as
for dry sanding untreated wooden surfaces.
• Avoid the accumulation of dust at the workplace, always
use a dust extraction system when grinding.
• Use a dust extraction system when grinding off residual
paint. Paint residues might smelt and then smudge both
workpiece and sanding sheet.
• Switch the device on before applying it to the workpiece.
Once the grinding process is concluded, lift the device off
the workpiece before you switch it off.
