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 Illumi-
nation
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 protection
is active, the temperature control/overload protection indica-
tor 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
possible 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 21 attached to the casing prevents acci-
dental touching of the saw blade during the working proce-
dure and may not be removed.
The outwardly curved edge over the extraction hood 15 pre-
vents the hand from slipping away in the sawing range.
Plunge Cutting (see figure I)
Plunge cuts may only be applied to soft mate-
rials, 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 13 touching the work-
piece and switch on. For machines with stroke rate control,
select the maximum stroke rate. Firmly hold the machine
against the workpiece and by tilting the machine, slowly
plunge the saw blade into the workpiece.
When the base plate 9 fully lays on the workpiece, continue
sawing along the desired cutting line.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.
Maintenance and Cleaning
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing transport and storage, remove the battery
from the power tool. There is danger of injury when
unintentionally actuating the On/Off switch.
For safe and proper working, always keep the
machine and ventilation slots clean.
Clean the saw blade holder regularly. For this, remove the
saw blade from the machine and lightly tap out the machine
on a level surface.
Heavy contamination of the machine can lead to malfunc-
tions. Therefore, do not saw materials that produce a lot of
dust from below or overhead.
