The optimal orbital action setting for the respective applica-
tion can be determined through practical testing. The follow-
ing recommendations apply:
– Select a lower orbital action setting (or switch it off) for a 

finer and cleaner cutting edge.

– For thin materials such as sheet metal, switch the orbital 

action off.

– For hard materials such as steel, work with low orbital 

action.

– For soft materials and when sawing in the direction of the 

grain, work with maximum orbital action.

Adjusting the Cutting Angle (see figure J)

The base plate 

9

 can be swivelled by 45° to the left or right for 

mitre cuts.

Remove the vacuum connection 

20

.

In mitre angle 0 °  there is a pin in a corresponding recess.

Loosen the screw 

24

 with the Allen key 

29

 until you can slide 

the base plate 

9

 in toward the battery 

1

. Let the pin slide into 

the guide groove.

For adjustment of precise mitre angles, swivel the base plate 

9

 to the desired position according to the scale 

25

. Every an-

gle can be adjusted to 45 °  using a protractor.

Tighten the screw 

24

 again.

The vacuum connection 

20

 and the splinter guard 

22

 cannot 

be used for bevel cuts.

Starting Operation

Removing the battery (see figure K)

To remove the battery 

1

 press the unlocking buttons 

2

 and 

pull out the battery downwards. 

Do not exert any force.

Switching On and Off

To 

start

 the machine, push the On/Off switch 

7

 forwards.

To 

switch off

 the power tool, push the On/Off switch 

7

 back 

to the 

“0”

 position.

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

Controlling the Stroke Rate

With the thumbwheel for stroke rate preselection 

4

, the 

stroke rate can be preset and changed during operation.

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. Remove the saw blade from the ma-
chine and allow the machine to cool down by running it for ap-
prox. 3 minutes at maximum stroke rate.

Temperature Dependent Overload Protection

In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the 
permitted battery temperature range, the speed is reduced or 
the power tool switches off. At reduced speed, the power tool 
will run again at full speed once the permitted battery temper-

ature is reached or the load is reduced. During automatic 
shut-down, switch off the power tool, allow the battery to cool 
down, then switch the power tool back on.

Temperature Control/Overload Protection Indicator

The red LED indicator 

6

 will help you in protecting the battery 

against overheating and the motor against overloading.

When the LED indicator 

6

continuously lights up red

, the 

temperature of the battery is too high and the machine 
switches off automatically.
– Switch the power tool off.
– Allow the battery to cool down before continuing to work.

The LED indicator 

6

flashes red

, the power tool is blocked 

and switches off automatically.

Remove the power tool from the workpiece.

As soon as the blockage is corrected, the power tool will con-
tinue to work at the set stroke rate.

Protection Against Deep Discharging

The lithium ion battery is protected against deep discharging 
by the “Electronic Cell Protection (ECP)”. When the battery is 
empty, the machine is switched off by means of a protective 
circuit: The inserted tool no longer rotates.

Switching on the LED Work Area Illumination

With the button 

3

 you can switch on the LED work light. The 

work light is switched off by default.

Restarting Protection

The restarting protection prevents uncontrolled starting of 
the machine after a power failure. Once the restarting protec-
tion is active, the temperature control/overload protection in-
dicator blinks 

6

 continuously.

To 

restart the operation

, switch the On/Off switch 

7

 to the 

Off position and start the machine again.

Note: 

When switching off and on again very quickly, it is pos-

sible that the restarting protection is triggered; this will pre-
vent the power tool from starting, although the On/Off switch 

7

 is actuated. Set the On/Off switch 

7

 to the off position, and 

then switch the power tool on again.

Working Advice



When sawing small or thin workpieces, always use a 

firm support.

Contact Protector

The contact protector 

19

 attached to the casing prevents 

accidental touching of the saw blade during the working pro-
cedure and may not be removed.

The outwardly curved edge over the extraction hood 

16

 pre-

vents the hand from slipping away in the sawing range.

Plunge Cutting (see figure G)



Plunge cuts may only be applied to soft materials, such 

as wood, gypsum plaster boards, etc.!

Use only short saw blades for plunge cutting. Plunge cutting is 
possible only with the mitre angle set at 0 ° .

Place the machine with the front edge of the base plate 

9

 on 

to the workpiece without the saw blade 

14

 touching the work-

piece and switch on. For machines with stroke rate control,
