Flap Disc

With the flap disc (accessory), curved surfaces

and profiles (contour sanding) can be worked.

Flap discs have a considerably higher service life

than sanding sheets, lower noise level and lower

sanding temperatures.

Cutting

When cutting, do not press, tilt or

oscillate the machine. Work with

moderate feed, adapted to the ma-

terial being cut.

Do not reduce the speed of running

down cutting discs by applying

sideward pressure.

When cutting profiles and square pipes, it is best

to start with the smallest cross section.

Cutting Stone

The machine must be used only for dry

cutting/grinding.

It is best to use a diamond cutting disc. As a

safety measure against jamming, use the cutting

guide 17 with the special dust extraction protec-

tion guard.

Operate the machine with dust extraction only. In

addition, wear a dust mask.

Slide the machine with moderate feed, adapted

to the material to be worked (Figure).

For cutting especially hard material, e. g., con-

crete with high pebble content, the diamond cut-

ting disc can overheat and become damaged as

a result. This is clearly indicated by circular

sparking, rotating with the diamond cutting disc.

In this case, interrupt the cutting process and al-

low the diamond cutting disc to cool by running

freely at no-load speed for a short time.

Noticeable decreasing work progress and circu-

lar sparking are indications of a diamond cutting

disc that has become dull. Briefly cutting into

abrasive material (e. g., lime-sand brick) can re-

sharpen the disc.

The

direction

which the cutting is

performed is impor-

tant.

The machine must

always work in an

up-grinding

motion.

Therefore,

never

move the machine in

the other direction!

Otherwise, the dan-

ger exists of it being

pushed

uncon-

trolled out of the cut.

If the machine should fail despite the care taken

in manufacturing and testing procedures, repair

should be carried out by an authorized after-sales

service centre for Bosch power tools.

In all correspondence and spare parts orders,

please always include the 10-digit article number

given on the nameplate of the machine.
