Noise/Vibration Information

Measured values determined according to
EN 60 745.
Typically the A-weighted sound pressure level of
the machine is 84 dB (A). Measurement uncer-
tainty K=3 dB.
When working, the noise level can exceed
85 dB (A).
Wear hearing protection!
The typical hand/arm vibration is below 2.5 m/s
For Your Safety
Read all instructions. Failure to
follow all instructions listed below
may result in electric shock, fire
and/or serious injury.
SAVE THESE INSTRUCTIONS.
When working with the machine, always
hold it firmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
securely than by hand.
Take protective measures when dust can
develop during working that is harmful to
one's health, combustible or explosive. Ex-
ample: Some dusts are regarded as carcino-
genic. Work with dust/chip extraction and
wear a dust mask.
Keep your workplace clean. Material mix-
tures are particularly dangerous. Dust of light
metal can be inflammable or explode.
Do not work materials containing asbes-
tos. Asbestos is considered carcinogenic.
Always wait until the machine has come to
a complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
Do not use a machine with a damaged
mains cable. Do not touch the damaged ca-
ble and pull the mains plug when the cable
is damaged while working. Damaged cables
increase the risk of an electric shock.
Connect machines that are used in the
open via a residual current device (RCD).
Use the machine only for dry sanding. Wa-
ter penetrating the power tool increases the
risk of an electric shock.
Apply the machine to the workpiece only
when switched on. Switch the machine off
only after it has been lifted away from the
workpiece. The power tool can move sud-
denly.
Never touch the running sanding belt. Dan-
ger of injury.

Pay attention that no persons are put at
.
risk through sparking. Remove any com-
bustible materials in the vicinity. Sparking
occurs when sanding metal materials.
Do not use worn, torn or heavily clogged
sanding belts. Damaged sanding belts can
tear apart and be thrown from the machine re-
sulting in possible personal injury.
Warning. Fire hazard! Avoid overheating of
the material being sanded and of the power
tool, and always empty the dust collector
before taking breaks. Sanding dust in the
dust bag, microfilter, paper bag (or in the filter
bag or filter of the vacuum cleaner) can self-ig-
nite under unfavourable conditions such as
from sparking while sanding metals. Especially
when it is mixed with particles of varnish or
polyurethane or other chemical materials, and
when the material being sanded is hot after
prolonged operation.

Intended Use

The machine is intended for dry sanding of wood,
plastic, metal, filler and coated surfaces – at high
removal rates.
Dust Extraction
External Dust Extraction (Accessory)
The machine can be plugged directly into the re-
ceptacle of a Berner all-purpose vacuum cleaner
with remote starting control. The vacuum cleaner
starts automatically when the machine is
switched on.
The vacuum cleaner must be suitable for the ma-
terial to be worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
For external dust extraction with a vacuum
cleaner, an extraction adapter must be used as
required (see accessories). Insert extraction
adapter and vacuum connection firmly.
