The emission values specifi ed (vibration, noise)
were measured in accordance with the test con-
ditions stipulated in EN 60745 and are intended
for machine comparisons. They are also used for
making preliminary estimates regarding vibration
and noise loads during operation.
The emission values specifi ed refer to the main
applications for which the power tool is used. If
the electric power tool is used for other applica-
tions, with other tools or is not maintained suf-
fi ciently prior to operation, however, the vibration
and noise load may be higher when the tool is
used. Take into account any machine idling times
and downtimes to estimate these values more
accurately for a specifi ed time period. This may
signifi cantly reduce the load during the machine
operating period.
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

,
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

speed.

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.

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.
The actual weight of the machine provides ad-
equate sanding pressure to produce good sanding
quality.
