trigger.
After switching off and before putting down the machine, allow

Hold the machine firmly with your hand when using and
whenever possible, move the machine in a steady motion

hollows on the surface.

Speed Controller

With the speed controller (4) you can adjust the speed according
to application. Select the appropriate speed setting and make
sure the sander dees not become overloaded and stops running.
Turn the speed controller (4) steplessly to the desired setting to
increase or decrease the speed. The controller can be adjusted
from 1 – 6. The speed rate can be changed during operation as
well.
Hint: The required speed rate for cutting resp. sanding a
workpiece depends on the material that you are going to process.
For best performance, make some practical tests.

Sanding

 Apply only moderate pressure on the machine. Too much
pressure will lead to jamming of the mechanism and will spoil
the result. Excessive pressure will overheat the machine.
 Always select abrasive paper with coarseness suited the
condition of the surface.
 Use finer papers in the consecutive sanding until the desired
smoothness is reached. If you desire a very smooth finish you
may slightly moisten the surface before the last sanding. This
will slightly swell the fibres and allow a smoother finish.
