ROTEX

Temperature cut-out
The machine power supply is limited and the

speed reduced if the motor exceeds a certain

temperature. The machine continues operat-

ing at reduced power to allow the ventilator

to cool the motor quickly. If the machine

temperature exceeds the maximum permit-

ted value for longer periods, the machine

switches off completely after approx. 40 sec-

onds and can only be switched on again once

the motor has cooled sufficiently.
7.2

Setting sanding motion [3]

The change-over switch [1-2] can be used

to set three different sanding motions.
L

This change-over can only be carried out

with the sanding pad stationary because

the switch is locked during operation.

Coarse sanding, polishing - ROTEX rota-

ry motion

The Rotex rotary motion is a combi-

nation of rotary and eccentric mo-

tions. This position is selected for

sanding with high output (coarse

sanding) and polishing.

Fine sanding - eccentric motion

This position is selected for sanding

with low output for a scratch-free

surface (fine sanding).

Triangular sanding and pad change [4]

This position is used for sanding

with the delta sanding pad and slat

sanding pad; the rotary motion is

blocked.
You can change the sanding pad in

this position.

The stop rod [1-8] blocks the in-

stallation of the sanding pad in the

change-over switch positions ROTEX rota-

ry motion and eccentric motion.

7.3

Changing sanding/polishing pad

[5]

Only use sanding and polishing pads that

are suitable for the maximum speed spec-

ified.

Tuned to the surface being processed, the

machine can be equipped with two sanding

pads of different hardnesses.
Hard: Coarse and fine sanding on surfaces.

Sanding edges.

Soft: Universal for coarse and fine sanding,

for flat and convex surfaces.
When the interface pad [1-12] is fitted on

the sanding pad, strength is reduced = extra

soft.

Following the sanding pad change, switch

the change-over switch [1-2] to the de-

sired sanding motion.

7.4

Changing sanding pad [6]

The delta sanding pad DSS-GE-STF-RO90

can be used for sanding close to borders, in

corners or on edges. The slat sanding pad

LSS-STF-RO90 can be used for sanding in

narrow gaps, e.g. louvres.
Observe the following instructions:
Work in corners and on edges tends to sub-

ject the tip to increased stress and results in

increased heat development. In such cases,

work with reduced contact pressure.
Delta sanding pad DSS-GE-STF-RO90

[7]
If the front tip of the StickFix pad [7-1] of

your delta sanding pad is worn, take it off

and turn it 120°.
Slat sanding pad LSS-STF-RO90 [8]
If the StickFix coating of the slat sanding pad

is worn, the complete table can be replaced.

Open the screws to do this [8-1].
7.5

Attaching sanding accessories

The suitable StickFix sandpaper and StickFix

sanding cloth can be attached quickly and

simply to the StickFix sanding pad.

Press the self-adhesive sanding accessory

onto the sanding pad [1-7].

7.6

Attaching polishing accessories

To prevent damage, PoliStick accessories

(polishing sponges, polishing felt, sheepskin)

must only be used on the special polishing

pad.

Press the self-adhesive polishing accesso-

ry onto the sanding pad [1-9].
