Assembly

 Before any work on the machine itself, pull the mains

plug.

Dust/Chip Extraction

 Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health. Touching or breathing-in the dusts can cause

allergic reactions and/or lead to respiratory infections of

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials

containing asbestos may only be worked by specialists.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the mate-

rials to be worked.

 Prevent dust accumulation at the workplace. Dusts can

easily ignite.

Mounting the Auxiliary Handle (see figure A)

 Operate your machine only with the auxiliary handle 3.

Screw the auxiliary handle 3 on the right or left of the machine

head depending on the working method.

Adjusting the Sanding Attachment (see figure B)

– Before adjusting the sanding attachment 10, completely

release clamping lever 5.

– Move the sanding attachment 10 accordingly to suit your

working conditions and working position.

– Close the clamping lever 5 and tighten it firmly.

Note: Clamping lever 5 is indexed (adjustable), allowing it to

be set to an ergonomically favourable or space-saving posi-

tion.

With the clamping lever 5 tightened, pull its lever away from

the machine head, turn it to the desired position and allow it

to engage again.

Changing the Sanding Belt (see figure C)

– Loosen fastening screw 9 and remove the attachment cov-

er 8.

– Press sanding attachment 10 via the supporting surface

14 against a sturdy object (e. g. a bench top) until the

sanding attachment 10 deflects. Remove the sanding belt

12.

– Firstly, position the new sanding belt 12 around on the

drive roller 7 and then around the deflection roller 13. Pay

attention that the arrow directions on the inside of the

sanding belt (if given) and on the attachment cover 8 of the

power tool correspond. Release the sanding attachment

10 again, so that the sanding belt 12 is tensioned.

– Mount the attachment cover 8 with fastening screw 9.

– Adjust the belt run as required, see section “Adjusting the

Belt Run”.

Adjusting the Belt Run (see figure D)

 Adjust the belt run only when the power tool is

switched off and disconnected from the power supply.

Turn adjustment screw 1 until the sanding belt 12 is posi-

tioned centred on deflection roller 13.

Selecting the Sanding Belt

Depending on the material to be worked and the required rate

of removal, different sanding belts are available:

Note: Depending on the application method and the material

being worked, either flexible of stiff sanding belts can be

used.

Changing the Sanding Arm (see figure E)

– Remove the sanding belt 12 (see section “Changing the

Sanding Belt”).

– Unscrew adjustment screw 1 and remove the sanding arm

16.

– Mount the new sanding arm 16 and fasten it with adjust-

ment screw 1.

– Pay attention that the sanding arm 16 is correctly mounted

according to figure E.

– Mount the sanding belt 12 (see section “Changing the

Sanding Belt”).

– Adjust the belt run (see section “Adjusting the Belt Run”).
