Working Advice

General Sawing Instructions



For all cuts, it must first be ensured that the saw blade 
at no time can come in contact with the fence, screw 
clamps or other machine parts. Remove any mounted 
auxiliary stops or adjust them accordingly.

Only saw materials which are permitted within the scope of 
the intended use.

Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.

Do not saw warped/bent workpieces. The workpiece must al-
ways have a straight edge to face against the fence.

Make sure that the retracting blade guard operates properly 
and that it can move freely. The retracting blade guard must 
open when the tool arm is guided downward. When the tool 
arm is guided upward, the retracting blade guard must close 
again over the saw blade and lock in the uppermost position 
of the tool arm.

Position of the Operator (see figure K)



Do not stand in a line with the saw blade in front of the 
machine. Always stand aside of the saw blade. 

This pro-

tects your body against possible kickback.

– Keep hands, fingers and arms away from the rotating saw 

blade.

– Do not cross your arms when operating the tool arm.

Permissible Workpiece Dimensions

 workpiece sizes:

Minimum

 workpiece sizes (= all workpieces that can be 

clamped left or right from the saw blade with the supplied ma-
terial clamp

): 100 x 40 mm (length x width)

Cutting depth, max.

(0 °/0 °): 70 mm

Replacing Insert Plates (see figure L)

The red insert plates 

23

 can become worn after prolonged 

use of the machine.

Replace defective insert plates.

– Bring the power tool into the working position.
– Unscrew  the  screws 

43

 with a hex key (4 mm) and remove 

the old insert plates.

– Insert the new right-hand insert plate.

– Screw the insert plate as far as possible to the right with 

the screws 

43

 so that the saw blade does not come into 

contact with the insert plate over the complete length of 
the possible slide motion.

– Repeat the work steps in the same manner for the left-hand 

insert plate.

Sawing



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

Otherwise the saw blade can become wedged in the 

workpiece.

Sawing without Slide Movement (Cutting Off) 
(see figure M)

– For cuts without slide movement (small workpieces), loos-

en the locking screw 

11

 if it is tightened. Push the tool arm 

all the way towards the fences 

6

 and 

21

 and retighten the 

locking screw 

11

.

– Adjust the requested mitre and/or bevel angle.
– Press the workpiece firmly against the fences

6

 and 

21

.

– Firmly clamp the workpiece as appropriate for its dimen-

sions.

– Switch on the machine.
– Press locking switch 

17

 and slowly guide the tool arm 

downward by the handle 

16

.

– Saw through the workpiece applying uniform feed.
– Switch off the machine and wait until the saw blade has 

come to a complete stop.

– Guide the tool arm slowly upward.

Sawing with Slide Movement

– For cuts using the slide device 

12

 (wide workpieces), loos-

en the locking screw 

11

 in case it is tightened.

– Adjust the requested mitre and/or bevel angle.
– Press the workpiece firmly against the fences

6

 and 

21

.

– Firmly clamp the workpiece as appropriate for its dimen-

sions.

– Pull the tool arm away from the fences 

6

 and 

21

 until the 

saw blade is in front of the workpiece.

– Switch on the machine.
– Press locking switch 

17

 and slowly guide the tool arm 

downward by the handle 

16

.

– Now push the tool arm toward the fences 

6

 and 

21

 and saw 

through the workpiece with uniform feed.

– Switch off the machine and wait until the saw blade has 

come to a complete stop.

– Guide the tool arm slowly upward.

Special Workpieces

When sawing curved or round workpieces, these must be es-
pecially secured against slipping. At the cutting line, no gap 
may exist between workpiece, fence and saw table.

Provide for special fixtures, if required.

Checking and Adjusting the Basic Adjustment



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

To ensure precise cuts, the basic adjustment of the machine 
must be checked and adjusted as necessary after intensive 
use.
