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.
Hand/arm vibrations
The vibration emission level given in this information
sheet has been measured in accordance with a standard-
ised test given in EN 60745 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.
Changing the tool.
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.
When changing application tools with sharp cutting
edges, use cover to protect yourself against
hand/arm injuries.
Additional operating instructions.
Guide the power tool toward the work piece only
when switched on.
Before using, sharpen used and even new cutter blades
with the cleaning block.
The symptom for worn blades is a clearly increased feed
force at lower working progress.
The application tool can be offset in 30° steps and fas-
tened in the most favourable working position.
Guide straight, bent or offset cutter blades at a right angle
to the window flange (see page 10–11, Cutter blades A
– D).
For U-shaped cutter blades, pay attention that the
traverse of the cutter blade is led parallel to the window
pane of the vehicle (see page 11, Cutter blades E – F).
The scraper knife is used for cutting back bond remain-
ders on the window flange or the pane. Before re-bond-
ing the vehicle window, cut back the remaining bead to a
height of approx. 2 mm (see page 11, Cutter blades G).
Notes on sanding.
Press the power tool with the sanding sheet briefly and
firmly against a flat surface and briefly switch the power
tool on. This provides for good adhesion and prevents
premature wear.
When only one tip or corner of the sanding sheet is
worn, it can be removed again and reattached turned by
120°.
Work with the entire surface of the sanding plate, not
only with the tip.
