1.4 Noise/vibration information
Measured values determined according to
EN 60745. Typically the A-weighted noise levels
of the tool are:
BS 75/BS 75 E
Sound pressure level 92/91 dB (A)
Sound power level 103/102 dB (A)
Measuring uncertainty allowance K = 3 dB
Wear ear protection!
Overall vibration levels a
h
(vector sum for three di-
rections) measured in accordance with EN 60745:
Handle
a
h
< 2.5 m/s²
K = 1.5 m/s²
Front handle a
h
= 7.5 m/s²
K = 2.0 m/s²
The specifi ed 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.
Increase possible for other applications, with oth-
er insertion tools or if not maintained adequately.
Take note of idling and downtimes of machine!
2 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.
3 Electronic adaptation of belt speed on
types BS 75 E
The control electronics permits the in-
fi nitely variable adaptation of the belt
speed.
Setting of set wheel Belt speed
(no-load)
1 200 m/min
2 240 m/min
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 infl uence
the choice, such as the surface and quality of the
workpiece, the make of abrasive belt and grit, skill
of the operator etc.
The fi gures shown in the table are only recom-
mended values.
Application Setting of set
wheel
Grit
Solid wood, fi ne 4 - 6 100
Veneer 3 - 4 120
Chipboard 5 - 6 100
Plastics 1 - 4 100
Steel 2 - 4 80
Paint remova 1 - 3 24
The belt speed is infi nitely 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.
4 Operation
Only to be switched on when the machine is
raised. Using the lock on button (1.2), the switch
(1.3) can be locked in the ON position. Before
sanding, check the alignment of the belt and if
necessary, adjust by turning the adjusting knob
(1.4) until the belt is fl ush with the outside edge
of the sanding face.
Using both hands, place the machine straight onto
the workpiece to be sanded.
