Operation



Before any work on the machine itself, pull the mains 
plug.

Transport Safety (see figure D)

The transport safety-lock 

30

 enables easier handling of the 

machine when transporting to various working locations.

Releasing the Machine (Working Position)

– Push the tool arm by the handle 

16

 down a little in order to 

relieve the transport safety-lock 

30

.

– Pull the transport safety-lock 

30

 completely outward.

– Guide the tool arm slowly upward.

Securing the Machine (Transport Position)

– Loosen the locking screw 

11

 if tightened. Pull the tool arm 

completely to the front and tighten the locking screw 
again.

– To lock the saw table 

22

, tighten the locking knob 

25

.

– Press locking switch 

17

 and slowly guide the tool arm 

downward by the handle 

16

.

– Guide the tool arm downward until the transport safety-

lock 

30

 can be pushed completely inward.

Preparing for Operation

Moving the Fence (see figure E)

You have to move the adjustable fence 

6

 to saw bevel angles.

– Loosen the locking screw 

40

 using the supplied hex key 

35

.

The two outer fixing screws must not be loosened!

– Pull the adjustable fence 

6

 completely outward.

– Retighten the locking screw 

40

.

After sawing the bevel angles, slide the adjustable fence 

6

back again (loosen the locking screw 

40

; slide the fence 

6

completely inward; retighten the locking screw).

Extending the Saw Table (see figure F)

Long workpieces must be underlaid or supported at their free 
end.

The saw table can be extended left and right with the saw-ta-
ble extensions 

3

.

– Loosen the clamping screw 

2

.

– Pull out the saw-table extension 

3

 to the desired length.

– Retighten the clamping screw 

2

 to fix the saw-table exten-

sion.

Clamping the Workpiece (see figure G)

To ensure optimum working safety, the workpiece must al-
ways be firmly clamped.
Do not saw workpieces that are too small to clamp.

– Press the workpiece firmly against the fences

6

 and 

21

.

– Insert the material clamp 

7

 provided into one of the holes 

41

 intended for it.

– Adapt the threaded rod 

42

 of the screw clamp to the work-

piece height.

– Firmly tighten the threaded rod 

42

, thus fastening the 

workpiece.

Adjusting the Cutting Angle

To ensure precise cuts, the basic adjustment of the machine 
must be checked and adjusted as necessary after intensive 
use (see “Checking and Adjusting the Basic Adjustment”, 
page 26).



Always tighten the locking knob 25 firmly before saw-
ing. 

Otherwise the saw blade can become wedged in the 

workpiece.

Adjusting Mitre Angles (see figure H)

The mitre angle can be set in the range from 47 ° (left side) to 
47 ° (right side).

– Loosen the locking knob 

25

 in case it is tightened.

– Pull the lever 

26

 and turn the saw table 

22

 until the desired 

mitre angle is indicated on the angle indicator 

24

.

– Tighten the locking knob 

25

 again.

For quick and precise setting of often used mitre angles,

detents 

28

 are provided on the saw table:

– Loosen the locking knob 

25

 in case it is tightened.

– Pull lever 

26

 and rotate the saw table 

22

 left or right to the 

requested detent.

– Release the lever again. The lever must be felt to engage in 

the detent.

– Tighten the locking knob 

25

 again.

Adjusting Bevel Angles (see figure I)

The bevel angle can be set in the range from 0 ° to 45 °.

– Pull the adjustable fence 

6

 completely outward.

– Loosen the lock lever 

10

.

– Tilt the tool arm by the handle 

16

 until the angle indicator 

32

 indicates the desired bevel angle.

– Hold the tool arm in this position and retighten the clamp-

ing lever 

10

.

For quick and precise setting of the standard angles 0 ° 
and 45 °,

 end stops are provided on the housing.

– Pull the adjustable fence 

6

 completely outward.

– Loosen the lock lever 

10

.

– To do so, swivel the tool arm by the handle 

16

 to the stop 

34

 to the right (0 °) or to the stop 

8

 to the left (45 °).

– Retighten the lock lever 

10

 again.

Starting Operation



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.

Products sold in AUS and NZ only

: Use a residual current de-

vice (RCD) with a rated residual current of 30 mA or less.

Switching On (see figure J)

To save energy, only switch the power tool on when using it.

– To 

start

 the machine, press the On/Off switch 

15

 and keep 

it pressed.
