5.3 Control electronics

The stroke rate of the orbital sander UVA 115 E can
be steplessly set at adjusting wheel 3 of the control
electronics from 4000 strokes/min to 24000
strokes/min.
With the control electronics, the sanding speed can
be adapted to the respective material. Thus, heat-
sensitive materials such as plastics, paints, varnishes
and glazes are protected against damage by
excessive sanding speeds. In addition, the abrasive
grid lasts longer as it does not get clogged. Thus,
when working with the control electronics when
sanding a wide variety of different materials, you
always obtain a sanding speed that is suitable for the
material.

5.4 Work instructions

The best sanding performance is achieved with slight
pressure.

Regularly remove deposited dust from the machine.
In the process, blow out the ventilation openings on
the motor.
