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,
