Bosch Power Tools

power tool.

 If accessories run faster than their rated

speed, they may break and fly off.

u

Do not use abrasive wheels as the application tool un-

der any circumstances.

Selecting the saw blade

You will find an overview of recommended saw blades at the

end of these operating instructions.

Removing the saw blade (see figure A)

To change tools, we recommend that you place the power

tool down on the front side of the motor housing.
– Press and hold the spindle lock button 

(5)

.

u

Do not press the spindle lock button

(5)

while the saw

spindle is moving.

 The power tool may become damaged

if this happens.

– Use the hex key 

(3)

 to undo the clamping bolt 

(25)

 in ro-

tational direction 

➊

.

– Swing the retracting blade guard 

(13)

 back and hold on

to it firmly.

– Remove the clamping flange 

(24)

 and the saw blade 

(23)

from the saw spindle 

(21)

.

Fitting the saw blade (see figure A)

To change tools, we recommend that you place the power

tool down on the front side of the motor housing.
– Clean the saw blade 

(23)

 and all the clamping elements

to be fitted.

– Swing the retracting blade guard 

(13)

 back and hold on

to it firmly.

– Place the saw blade 

(23)

 on the mounting flange 

(22)

.

The cutting direction of the teeth (direction of the arrow

on the saw blade) must match the rotational direction of

the arrow on the retracting blade guard 

(13)

.

– Attach the clamping flange 

(24)

 and screw in the clamp-

ing bolt 

(25)

 in rotational direction 

➋

. Ensure that the

mounting flange 

(22)

 and clamping flange 

(24)

 are in-

stalled in the correct position.

– Press and hold the spindle lock button 

(5)

.

– Use the hex key 

(3)

 to tighten the clamping bolt 

(25)

 in

rotational direction 

➋

. The tightening torque should be

6–9 Nm, which corresponds to hand-tight plus ¼ turn.

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.

Fitting the dust extraction adapter (see figure B)

Push the dust extraction adapter 

(28)

 onto the chip ejector

(16)

 until it clicks into place. Then secure the dust extraction

adapter 

(28)

 in place with the screw 

(27)

.

A dust extraction hose with a diameter of 35 mm can be con-

nected to the dust extraction adapter 

(28)

.

u

The dust extraction adapter must only be fitted if an

external dust extraction system is connected.

 Other-

wise the extraction duct can become clogged.

u

No dust bags should be connected to the dust extrac-

tion adapter

. Otherwise the extraction system can be-

come clogged.

To ensure optimum extraction, the dust extraction adapter

(28)

 must be cleaned regularly.

External dust extraction

Connect the extraction hose 

(35)

 to a dust extractor (ac-

cessory). You will find an overview of connecting to various

dust extractors at the end of these operating instructions.
The power tool can be directly connected to the socket of a

Bosch all-purpose dust extractor with remote starter. This

dust extractor is started up automatically when the power

tool is switched on.
The dust extractor must be suitable for the material being

worked.
When extracting dry dust that is especially detrimental to

health or carcinogenic, use a special dust extractor.

Operation

Operating modes

u

Remove the battery before carrying out any work on

the power tool.

Setting the cutting depth (see figure C)

u

Adapt the cutting depth to the thickness of the work-

piece

. A space of less than the height of one full tooth

should be visible under the workpiece.

Loosen the clamping lever 

(29)

. For a smaller cutting depth,

pull the saw away from the base plate 

(6)

; for a larger cutting

depth, push the saw towards the base plate 

(6)

. Adjust the

desired cutting depth at the cutting-depth scale. Retighten

the clamping lever 

(29)

.

The clamping force of the clamping lever 

(29)

 can be read-

justed. To do so, unscrew the clamping lever 

(29)

 and

retighten it in a position offset by at least 30° in an anticlock-

wise direction.

Setting the mitre/bevel angle (GKS 18V-57 G)

We recommend that you place the power tool down on the

front side of the protective guard 

(17)

.
