Sanding Sheets without Velcro Backing

(see figures B–D)

n Press the release button 8 and keep it depressed.

o Guide the sanding sheet 7 to the stop under the

opened front clamping bracket 9 and let go of the

release button 8 again. Pay attention that the sand-

ing sheet is clamped centrally.

p Press the sanding sheet clamp 5 inward and pivot

it to the stop.

q Fold the sanding sheet 7 firmly around the sanding

plate. Guide the other end of the sanding sheet 7

between the rear clamping bracket and the red

roller on the clamping bracket 5.

r Hold the sanding sheet tensely and press the

clamping bracket 5 toward the sanding plate to

lock the sanding sheet.

Sanding sheets without holes, e. g. from rolls or by the

meter, can be punctured with the perforating tool 10 for

use with dust extraction. For this, press the machine

with the mounted sanding sheet onto the perforating

tool (see figure E).

To remove the sanding sheet 7, loosen the clamping

bracket 5 and pull out the sanding sheet from the rear

holding fixture. Press the release button 8 and com-

pletely remove the sanding sheet.

Selecting the Sanding Sheet

Depending on the material to be worked and the

required rate of material removal, different sanding

sheets are available:

Replacing the Sanding Plate

(see figure F)

Before any work on the machine itself, pull the

mains plug.

The sanding plate 6 can be replaced, if required.

Unscrew the 4 screws 11 completely and remove the

sanding plate 6. Attach the new sanding plate 6 and

tighten the screws again.

Operation

Starting Operation

Observe correct mains voltage! The voltage of the

power source must agree with the voltage specified on

the nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

Switching On and Off

To start the machine, press the On/Off switch 2 and

keep it depressed.

To lock the pressed On/Off switch 2, press the lock-

on button 3.

To switch off the machine, release the On/Off switch

2 or when it is locked with the lock-on button 3, briefly

press the On/Off switch 2 and then release it.

Preselecting the Orbital Stroke Rate

With the thumbwheel for preselection of the orbital

stroke rate 1, you can preselect the required orbital

stroke rate, even during operation.

The required stroke rate depends on the material and

the working conditions and can be determined through

practical testing.

Operating Instructions

B Wait until the machine has come to a stand-

still before placing it down.

The removal capacity during sanding is mainly deter-

mined by the selection of the sanding sheet as well as

the preselected orbital stroke rate.

Only flawless sanding sheets achieve good sanding

capacity and extend the service life of the machine.

Pay attention to apply uniform sanding pressure; this

increases the working life of the sanding sheets.

Intensifiying the sanding pressure does not lead to an

increase of the sanding capacity, but to increased wear

of the machine and the sanding sheet.

A sanding sheet that has been used for metal should

not be used for other materials.

Use only original Bosch sanding accessories.
