Attaching/changing the sanding sheet on the sanding
plate

The sanding plate 

(16)

 is fitted with a hook-and-loop fasten-

ing, allowing sanding sheets with a hook-and-loop backing to
be secured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate 

(16)

before fitting the sanding sheet 

(17)

 to facilitate maximum

adhesion.
Position the sanding sheet 

(17)

 so that it is flush with one

side of the sanding plate 

(16)

, then place the sanding sheet

on the sanding plate and press it on firmly.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.
To remove the sanding sheet 

(17)

, take hold of it by a corner

and pull it away from the sanding plate 

(16)

.

You can use all sanding sheets, polishing and cleaning
fleeces from the Delta 93 mm series in Bosch’s range of ac-
cessories.
Sanding accessories such as fleece/polishing felt are at-
tached to the sanding plate in the same way.

Dust/chip extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.

Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity. 
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-

terial wherever possible.

– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.

u

Avoid dust accumulation at the workplace. 

Dust can

easily ignite.

Connecting the dust extraction system (see figure A)

The dust extraction system 

(15)

 is only designed for use

with the sanding plate 

(16)

; it serves no purpose when used

together with other application tools.
Always connect a dust extraction system for sanding.
Remove the application tool and the depth stop 

(12)

 for fit-

ting the dust extraction system 

(15)

 (accessory).

Slide the dust extraction system
