switched on and enables operation using a 16 A
fuse.
Note: If the power tool runs at full speed immedi-
ately after being switched on, this means that the
starting current limitation and restarting protection
mechanisms have failed. The power tool should
be sent immediately to an after-sales service.
Constant Electronic control
The Constant Electronic keeps the speed at no
load and under load virtually consistent, guaran-
teeing uniform performance.
Speed preselection (BAGX 125 1700W)
You can preselect the required speed using the
speed preselection thumbwheel (5), even during
operation. The required speed depends on the
material and the working conditions; it can be as-
certained through practical tests.

The rated speed of the accessory must be at

the power tool. Accessories running faster
than their rated speed can break and fly apart.

Working advice

English
Pull the plug out of the socket before carry-
u
ing out any work on the power tool.
Exercise caution when cutting slots in struc-
u
tural walls; see the "Information on structural
design" section.
Clamp the workpiece if it is not secure under
u
its own weight.
Do not load the power tool so heavily that it
u
comes to a stop.
If the power tool has been subjected to a
u
heavy load, continue to run it at no-load for
several minutes to cool down the accessory.
Do not use the power tool with a cut-off
u
stand.
Do not touch grinding and cutting discs until
u
they have cooled down. The discs can be-
come very hot while working.
Rough grinding
English
Never use cutting discs for rough grinding.
u
The best rough grinding results are achieved with
a set angle of 30° to 40°. Move the power tool
back and forth with moderate pressure. This will

ensure that the workpiece does not become too
hot or discolour and that grooves are not formed.
Flap Disc
With the flap disc (accessory), curved surfaces
and profiles can be worked. Flap discs have a
considerably higher service life, lower noise levels
and lower sanding temperatures than conven-
tional sanding sheets.
English
Cutting Metal
u
When carrying out abrasive cutting, use a moder-
English
ate feed that is suited to the material being ma-
chined. Do not exert pressure on the cutting disc
and do not tilt or swing the power tool.
Do not attempt to reduce the speed of a cutting
disc coming to a stop by applying pressure from
the side.

Cutting stone
u
u
u
For best results when cutting stone, use a dia-
mond cutting disc.
When using the extraction guard for cutting with a
cutting guide (18), the vacuum cleaner must be
approved for vacuuming stone dust. Suitable va-
cuum cleaners are available from Berner.
larly hard materials such as concrete with a high
pebble content, the diamond cutting disc can
overheat and become damaged as a result. This
is clearly indicated by circular sparking, rotating
with the diamond cutting disc.
English
English
Always use the protective guard for cutting
(9) when cutting bonded abrasives.
The power tool must
always work in an up-
grinding motion. Other-
wise, there is a risk
that it will be pushed
uncontrolled out of
the cut. For best res-
ults when cutting pro-
files and rectangular
tubing, start at the
smallest cross section.
English
Provide sufficient dust extraction when cut-
ting stone.
Wear a dust mask.
The power tool may be used only for dry cut-
ting/grinding.
Switch on the power
tool and position it with
the front part of the
cutting guide on the
workpiece. Move the
power tool with a mod-
erate feed motion that
appropriate to the ma-
terial being machined.
