7.1 Electronics
Smooth start-up
The electronically controlled smooth start-up
ensures that the machine starts up jolt-free.
Constant speed
The preselected motor speed is kept constant
through electronic control. This means that, if the
machine is used as intended (reasonable contact
pressure), a constant sanding speed is achieved.
Setting and adjusting the speed
The speed can be set [1-3] between 6000 and
12000 rpm using the adjusting wheel.
This enables you to optimise the sanding speed
to suit the material (see chapter 8).
7.2 Changing sanding pad [3]
An optimal work result can only be
achieved using original accessories and
consumables. The use of non-original
accessories or consumables invalidates
the right to claim under warranty.
