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

Before transporting the power tool, the following steps must 
be carried out:

– Bring the power tool into the table saw working position. 

(see “Working Position”, page  47)

– Position the parallel guide 

61

 completely over the protec-

tion guard 

63

.

To lock the parallel guide, push the clamping knob

Operation as Chop and Mitre 
Saw



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

Working Position (see figure

A)

If the power tool is still in the condition as delivered or if the 
power tool was used as a table saw, then the following steps 
must be carried out before using as a chop and mitre saw:

– Loosen both clamping levers 

68

 below the saw table 

59

.

– Pull the saw table upward to the stop.
– Hold the saw table in this position and tighten the clamping 

levers again.

– Position the parallel guide 

61

 over the saw blade as a pro-

tective measure.

– Push the tool arm by the handle 

18

 down a little in order to 

relieve the transport safety-lock 

38

.

– Pull the transport safety-lock 

38

 completely outward.

– Remove the lower saw blade cover 

66

 and slide it into the 

groove on the right-hand side of the parallel guide 

61

.



Do not throw away the lower saw blade cover! 

If the low-

er saw blade cover is not used, it is not possible to operate 
the combination saw as a table saw!

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

– Loosen both hex socket screws 

41

 with the hex key 

5

 pro-

vided. 

– Pull out the saw table extension 

29

 to the stop and tighten 

the hex socket screws again.

Clamping the Workpiece (see figure

C)

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 fence

30

.

– Insert the material clamp 

21

 provided into one of the holes 

28

 intended for it.

– Loosen the wing bolt 

43

 and adapt the material clamp to 

the workpiece. Tighten the wing bolt again.

– Firmly clamp the workpiece by turning the threaded rod 

42

 in clockwise direction.

Moving the Fence (see figure

You have to move the adjustable fence 

31

 to saw bevel an-

gles.

–

Loosen

 locking screw 

44

.

– Pull the adjustable fence 

31

 completely outward.

– Retighten the locking screw 

44

.

After sawing the bevel angles, slide the adjustable fence 

31

back again (loosen the locking screw 

44

; slide the fence 

31

completely inward; retighten the locking screw).

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 45).



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

Otherwise the saw blade can become wedged in the 

workpiece.

– Bring the power tool into the chop and mitre saw working 

position.  (see “Working Position”, page 42)
