Starting Operation

f

Observe correct mains voltage! The voltage 
of the power 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.

The “Power Light” 

10

 is lit when the mains plug 

is inserted, and allows for illumination of the 
working range under unfavourable light condi-
tions.

Switching On and Off

To 

start

 the machine, 

first

 push the lock-off but-

ton for the On/Off switch 

7

 and 

then

 press the 

On/Off switch 

8

 and keep it pressed.

To switch off the machine, 

release

 the On/Off 

switch 

8

.

Note: 

For safety reasons, the On/Off switch 

8

cannot be locked; it must remain pressed during 
the entire operation.

Controling the Stroke Rate

Increasing or reducing the pressure on the 
On/Off switch 

8

 enables stepless stroke-rate 

control of the switched-on machine.
Light pressure on the On/Off switch 

8

 results in 

a low stroke rate. Increasing the pressure also 
increases the stroke rate.
The required stroke rate is dependent on the 
material and the working conditions and can be 
determined by a practical trial.
Reducing the stroke rate is recommended when 
the saw blade engages in the material as well as 
when sawing plastic and aluminium.
After longer periods of work at low stroke rate, 
the machine can heat up considerably. Allow the 
machine to cool down by running it for approx. 
3 minutes at maximum stroke rate.

Working Advice

Tips

f

When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material suppliers.

Check wood, press boards, building materials, 
etc. for foreign objects such as nails, screws or 
similar, and allways use the correct sawblade.
Switch the machine on and guide it toward the 
workpiece. Position the footplate 

2

 onto the sur-

face of the work and saw through the material 
applying uniform contact pressure and feed. Af-
ter completing the working procedure, switch 
the machine off.
If the saw blade should jam, switch the machine 
off immediately. Widen the gap somewhat with 
a suitable tool and pull out the machine.

Plunge Cutting (see figures E – F)

f

The plunge cutting procedure is only suita-
ble for treating soft materials such as wood, 
plaster board or similar! Do not work metal 
materials with the plunge cutting proce-
dure!

Use only short saw blades for plunge cutting.
Place the machine with the edge of the footplate 

2

 onto the workpiece and switch on. For power 

tools with stroke speed control, set the maxi-
mum stroke speed. Press the power tool firmly 
against the workpiece and allow the saw blade 
to slowly plunge into the workpiece.
As soon as the footplate 

2

 fully lays on the sur-

face of the workpiece, continue sawing along-
side the desired cutting line.
For certain work, the saw blade 

1

 can also be in-

serted turned through by 180 °  and the sabre 
saw can be guided accordingly in a reversed 
manner.

Flush Cuts (see figure G)

Using elastic bimetal saw blades, items still at-
tached to a wall (e. g. projecting building ele-
ments such as water pipes, etc.) can be sawn off 
flush at the wall.

f

Pay attention that the saw blade always ex-
tends beyond the diameter of the material 
being worked. There is danger of kickback.

Position the saw blade directly against the wall 
and apply some lateral pressure via the tool until 
the footplate faces against the wall. Switch the 
power tool on and saw through the workpiece, 
applying constant lateral pressure.
