Vibration emission value ah (vector sum for three
directions) and uncertainty K measured in ac-
cordance with EN 62841 (see EU Declaration of
Conformity):
Sanding a

= 5.6 m/s²
K = 1.5 m/s²
The specified emissions values (vibration, noise)
- are used to compare machines.
- They are also used for making preliminary
estimates regarding vibration and noise loads
during operation.
- They represent the primary applications of the
power tool.
CAUTION
The noise emissions during actual use
of the power tool can differ from the
declared values depending on the ways
in which the tool is used especially what
kind of workpiece is processed.
Identify safety measures to protect the
operator that are based on an estimation
of exposure in the actual conditions of use
(taking account of all parts of the operat-
ing cycle such as the times when the tool
is switched off and when it is running idle
in addition to the trigger time).

Intended use
All-purpose sander for sanding wood, plastics and
building materials; using the appropriate sanding
belts, surfaces, edges, lippings and rebates can be
rough or fine sanded; with the Type BS 75 E - Set,
using the sanding frame, high-grade workpiece
surfaces such as veneers etc., can be sanded.
The operation and application of the sander can
be extended with the accessories listed.
Metals and materials that contain asbestos must
not be processed. Sparks may be created when
processing metals, which increase the risk of fire.
Generally accepted accident prevention regula-
tion and the enclosed »Safety Instructions« for
the avoidance of accidents when working with the
electric tools, must be complied with.
The manufacturer is not liable for damages
caused by unauthorized changes or the use of
external accessories with the machine.
The user is liable for damage and injury
resulting from incorrect usage!

Mains supply
The mains voltage must match the voltage on
the rating plate.
Fuse for 230 V:
10 Amp slow action or equivalent
automatic cut-out.
Connection is also possible to sockets without an
earthing contact, as protective insulation (Class
II) is present.
Only use a run out extension lead with a cross
section of 3 x 1.5 mm
2
, max. 20 m, (3 x 2.5 mm
2
,
max. 50 m). When tool is used outdoors, use only
extension cords intended for use outdoors and
so marked.

Electronic adaptation of belt speed on
types BS 75 E
The control electronics permits the in-
finitely variable adaptation of the belt
speed.
Setting of set wheel
Belt speed
(no-load)

3
300 m/min
4
340 m/min
5
360 m/min
6
380 m/min
The most suitable belt speed must be found
by trial and error when starting work, because
there are several prime factors which influence
the choice, such as the surface and quality of the
workpiece, the make of abrasive belt and grit, skill
of the operator etc.
The figures shown in the table are only recom-
mended values.

The belt speed is infinitely adjustable up to the
maximum setting while work is in process.
This is done by turning the set wheel (2.1).
It must be remembered that at low speed settings
the sander has a lower power output. In order to
avoid overloading, therefore, the speed has to be
increased by turning the set wheel if it turns out
that the belt speed falls sharply while working.
