Clean the ventilation openings on the power tool at regu-
lar intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
After working gypsum-containing materials: Blow out the
ventilation openings of the power tool and the switch ele-
ment with dry and oil-free compressed air. Otherwise,
gypsum-containing dust can settle in the power tool
housing and switch element, which can harden in connec-
tion with humidity. This can impair the switching mecha-
nism.
Use and handling of the battery (battery pack).
To avoid hazardous situations such as burns, fire, explo-
sion, skin injuries, and other injuries when handling the
battery, observe the following instructions:
Batteries must not be disassembled, opened or reduced
in size. Do not subject batteries to mechanical impact or
shock. Hazardous vapours and fluid can escape in case of
damage and improper use of the battery. The vapours can
irritate the respiratory system. Liquid ejected from the
battery may cause skin irritations or burns.
When battery fluid from a damaged battery has come into
contact with objects close by, check the respective com-
ponents, clean them or replace them as required.
Keep the battery away from heat and fire. Do not store the
battery in direct sunlight.
Do not remove the battery from its original packaging
until it is going to be used.
Before any work on the machine itself, remove the bat-
tery from the power tool. If the power tool accidentally
starts, there is danger of injury.
Remove the battery only when the power tool is switched
off.
Keep the battery away from children.
Keep the battery clean and protect it against moisture
and water. Clean contaminated battery terminals and
power tool connections with a dry, clean cloth.
Use only intact original Berner batteries that are intended
for your power tool. When working with and charging
incorrect, damaged, repaired or reconditioned batteries,
imitations or other brands, there is danger of fire and/or
explosion.
Follow the safety warnings in the operating instructions
of the battery charger.
Handling hazardous dusts
For work procedures with this power tool where mate-
rial is removed, dusts develop that can be hazardous to
one's health.
Contact with or inhaling some dust types, e. g. asbestos
and asbestos-containing materials, lead-containing coat-
ings, metal, some wood types, minerals, silicate particles
from materials containing stone, paint solvents, wood
preservatives, antifouling paints for vessels, can trigger
allergic reactions to the operator or bystanders and/or
lead to respiratory infections, cancer, birth defects or
other reproductive harm. The risk from inhaling dusts
depends on the exposition. Use dust extraction matched
appropriately for the developing dust, as well as personal
protective equipment and provide for good ventilation of
the workplace. Leave the processing of asbestos-contain-
ing materials to specialists.
Wood and light-metal dust, hot mixtures of grinding dust
and chemical materials can self-ignite under unfavourable
conditions or cause an explosion. Avoid sparking in the
direction of the dust collector as well as overheating of
the power tool and the materials being sanded, empty the
dust collector/container in time, observe the material
manufacturer's working instructions, as well as the rele-
vant regulations in your country for the materials being
worked.
Emission values for vibration
Measured noise values determined according
to EN 62841.
Typically the A-weighted noise levels of the product are:
Sound pressure level 74 dB(A); Sound power level
85 dB(A). Uncertainty K=3 dB.
Wear hearing protection!

The vibration emission level given in this information
sheet has been measured in accordance with a standard-
ised 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 opera-
tor from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
of work patterns.
Operating Instructions.
Do not use accessories not specifically intended and rec-
ommended for this power tool by Berner. The use of non-
original Berner accessories can lead to overheating of the
power tool and destroy it.
Changing the tool (see pages 5/6).
Do not switch the power tool on while the clamping
lever is open. Otherwise there is danger of crushes
or contusions to the hand and fingers.
