

Take care during the mounting that the cutting direc-
tion of the teeth (direction of the arrow on the saw 
blade) agrees with the direction of the arrow on the re-
tracting blade guard!

– Mount the clamping flange 

50

, the washer 

49

 and the hex-

agon bolt 

48

.

Press spindle lock 

42

 until it engages and tighten hexagon 

bolt 

48

 with the supplied socket spanner 

35

 in anticlock-

wise direction with a tightening torque of approx. 
15 – 23 Nm.

– Push the locking lever 

43

 and guide the retracting blade 

guard 

10

 down again.

– Retighten the screws 

47

 and 

46

.

Operation



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

Transport Safety (see figure E)

The transport safety-lock 

28

 enables easier handling of the 

machine when transporting to various working locations.

Releasing the Machine (Working Position)

– Push the tool arm by the handle 

7

 down a little in order to 

relieve the transport safety-lock 

28

.

– Pull the transport safety-lock 

28

 all the way outward and 

turn it by 90 °. Allow the transport safety-lock to engage in 
this position.

– Guide the tool arm slowly upward.

Securing the Machine (Transport Position)

– Loosen the locking screw 

31

 if tightened. Pull the tool arm 

completely to the front and tighten the locking screw 
again.

– Screw the depth stop 

58

 completely to the top (see “Ad-

justing the Depth Stop”, page 32).

– To lock the saw table 

18

, tighten the locking knob 

14

.

– Pull the transport safety-lock 

28

 all the way outward and 

turn it by 90 °. Allow the transport safety-lock to engage in 
this position.

– Push the locking lever 

43

 and at the same time lower the 

tool arm via handle 

7

 until the transport safety-lock engag-

es in the end position.
The tool arm is now securely locked for transport.

Preparing for Operation

Extending the Saw Table (see figure F)

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

– Push tensioning lever 

39

 upward.

– Pull out saw-table extension 

38

 to the desired length (max. 

225 mm).

– Lock in place by pushing tensioning lever 

39

 down again.

Extending the Fence (see figure G)

For bevel angles, the fence extensions 

21

 must be moved.

– Loosen the locking screw 

22

 and pull the fence extension 

21

 completely outward.

– Retighten the screw again.

Clamping the Workpiece (see figure H)

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



While clamping the workpiece, do not reach under the 
clamping lever of the quick-action clamp with your fin-
gers.

– Press the workpiece firmly against the fence

20

.

– Insert the quick-action clamp 

23

 into one of the holes 

52

intended for this purpose.

– Adapt the quick-action clamp to the workpiece by turning 

the threaded rod 

54

.

– Push on the clamping lever 

53

 in order to clamp the work-

piece.

Adjusting Mitre Angles

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 34).



Always tighten the locking knob 14 firmly before saw-
ing. 

Otherwise the saw blade can become wedged in the 

workpiece.

Adjusting Standard Mitre Angles (see figure I)

For quick and precise adjustment of commonly used mitre an-
gles, detents 

17

 have been provided for on the saw table:

– Loosen the locking knob 

14

 in case it is tightened.

– Pull lever 

15

 and rotate the saw table 

18

 left or right to the 

requested detent.

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

the detent.

Adjusting Any Mitre Angle (see figure J)

The mitre angle can be set in the range from 52 ° (left side) to 
60 ° (right side).

– Loosen the locking knob 

14

 in case it is tightened.

– Pull lever 

15

 and at the same time push the locking bracket 

13

 until it engages in the groove intended for this. The saw 

table can be moved freely now.

– Turn the saw table 

18

 left or right by the locking knob until 

the angle indicator 

66

 indicates the requested mitre angle.

– Tighten the locking knob 

14

 again.

Adjusting Bevel Angles

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 34).

The vertical bevel angle can be adjusted in a range from 47 ° 
(leftward) to 47 ° (rightward).

For quick and precise adjustment of commonly used bevel an-
gles, stops are provided for 0 °, 45 ° and 33.9 ° angles.
