3. SWITCHING ON/OFF (See Fig.4 )

On /Off Switch 

Depress to start and release to stop your tool.

Lock-On Switch

Depress on/off switch (2) then lock-on button 

(1), release on/off switch first and lock-on 

button second. Your switch is now locked on for 

continuous use. To switch off your sander just

4. AUXILIARY HANDLE (See Fig.5 )

The auxiliary handle makes possible comfortable 

handling and optimum force application, especially 

for high material removal. The position of the 

auxiliary handle can be adjusted using winged 

screw.

5. SPEED PRE-SELECTION

The required speed can be pre-selected with the 

variable speed control (8) 

(See Fig.6 )

(whilst running).

6. SANDING PLATE BRAKE

An integrated sanding plate brake reduces the 

speed when running at no load so that scoring is 

avoided when placing the machine on the work 

piece. A continuously increasing no-load speed 

over the course of time indicates that the sanding 

plate brake is worn and must be replaced by an 

authorized customer service location.

7. SANDING SURFACES 

Place the machine with the complete Sand 

paper on the surface to be worked. Ensure 

uniform sanding pressure. Less sanding pressure 

increases the sanding capacity and protects 

the machine and the sanding tool. The removal 

capacity and the sanding pattern are determined 

mainly by the selection of the Sand paper (grain 

size), the speed of the sanding plate and the 

application pressure.

Rough Sanding

Attach a Sand paper with coarse grain. Apply only 

light sanding pressure to achieve increased material 

removal.

Fing Sanding

Attach a Sand paper with fine grain. With moderate 

pressure, move the machine in a circular pattern or 

alternately in lengthwise and crosswise directions 

over the work piece. Do not tilt the machine to
