f

The spindle lock button 25 may be actuated only when 

the saw spindle is at a standstill. 

Otherwise, the power 

tool can be damaged.

– With the Allen key 

5

, unscrew the clamping bolt 

20

 turning 

in rotation direction 

n

.

– Remove the clamping flange 

21

 and the saw blade 

22

 from 

the saw spindle 

26

.

Mounting the Saw Blade (see figure A)

Adjust the maximal cutting depth, see section “Adjusting the 

Cutting Depth”.
For changing the cutting tool, it is best to place the machine 

on the face side of the motor housing.
– Pivot  lever 

3

 toward the front.

– Push lock-off button 

2

 toward the front and press the saw 

toward base plate 

7

 until it engages in the position for 

changing the saw blade.

– Clean the saw blade 

22

 and all clamping parts to be assem-

bled.

– Place the saw blade 

22

 on to the mounting flange 

23

. The 

cutting direction of the teeth (direction or arrow on saw 

blade) and the direction-of-rotation arrow on the blade 

guard 

15

 must correspond.

– Mount the clamping flange 

21

 and screw in the clamping 

bolt 

20

 turning in rotation direction 

o

. Observe correct 

mounting position of mounting flange 

23

 and clamping 

flange 

21

.

– Press the spindle lock button 

25

 and keep it pressed.

– With the Allen key 

5

, tighten the clamping bolt 

20

 turning 

in rotation direction 

o

. The tightening torque is between 

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

– Pivot  lever 

3

 back. When doing this, the saw retracts back 

to the starting position.

Dust/Chip Extraction

f

Before any work on the machine itself, pull the mains 

plug.

f

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.

– As far as possible, use a dust extraction system suita-

ble for the material.

– 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 

materials to be worked.

f

Prevent dust accumulation at the workplace. 

Dusts can 

easily ignite.

External Dust Extraction

Mount the vacuum hose 

31

 (accessory) on to the saw dust 

ejector 

18

.Connect the vacuum hose 

31

 to a vacuum cleaner 

(accessory). An overview for connecting to various vacuum 

cleaners can be found at the end of this manual.
The machine can be plugged directly into the receptacle of a 

Bosch all-purpose vacuum cleaner with remote starting con-

trol. The vacuum cleaner starts automatically when the ma-

chine is switched on.
The vacuum cleaner must be suitable for the material being 

worked.
When vacuuming dry dust that is especially detrimental to 

health or carcinogenic, use a special vacuum cleaner.

Operation

Operating Modes

f

Before any work on the machine itself, pull the mains 

plug.

Adjusting the Cutting Depth (see figure B – C)

f

Adjust the cutting depth to the thickness of the work-

piece. 

Less than a full tooth of the blade teeth should be 

visible below the workpiece.

Turn cutting-depth indicator 

8

 to the bottom position 

n

 for 

sawing without guide rail, or to the upper position 

o

 for saw-

ing with guide rail.
Press slider 

27

 and adjust the desired cutting depth (material 

thickness + tooth height of the saw blade) on cutting-depth 

scale 

6

.

Adjusting the Cutting Angle

Loosen the wing bolts 

11

 and 

17

. Tilt the saw sidewards. Ad-

just the desired measure on the scale 

9

. Tighten the wing 

bolts 

11

 and 

17

 again.

The mitre angle of the saw can be adjusted to – 1 °  or + 47 ° . 

For the – 1 °  mitre angle, additionally push button 

16

 while 

tilting, or for the + 47 °  mitre angle, push button 

12

 while tilt-

ing.

Note: 

For bevel cuts, the cutting depth is smaller than the set-

ting indicated on the cutting-depth scale 

6

.

Cutting Marks (see figure D)

The 0 °  cutting mark (

32

) indicates the position of the saw 

blade for straight cuts. The 45 °  cutting mark (

33

) indicates 

the position of the saw blade for 45 °  cuts without using the 

guide rail.

Starting Operation

f

Observe correct mains voltage! The voltage of the pow-

er 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, 

first

 push the lock-off button for the 

On/Off switch 

2

 and 

then

 press the On/Off switch 

1

 and keep 

it pressed.
Actuating lock-off button 

2

 releases the plunging device at the 

same time, and allows for the saw to be pushed down. This 

makes the saw blade plunge into the workpiece. When pulling
