For adjustment of precise mitre angles, swivel the
base plate
9
to the desired position according to
the scale
26
. Every angle can be adjusted to 45 °
using a protractor.
Tighten the screw
24
again.
The vacuum connection
18
and the splinter guard
15
cannot be used for bevel cuts.
Starting Operation
Inserting the battery
Note:
Use of batteries not suitable for the machine
can lead to malfunctions of or cause damage to the
power tool.
Insert the charged battery
1
into the battery port
until it can be felt to engage and is seated flush.
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 mate-
rial and the working conditions and can be deter-
mined 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 machine and allow the machine
to cool down by running it for approx. 3 minutes at
maximum stroke rate.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot
be overloaded. 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
temperature is reached or the load is reduced. Dur-
ing 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 continue 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 protection is active, the temperature
control/overload protection indicator blinks
6
con-
tinuously.
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 quick-
ly, it is possible that the restarting protection is trig-
gered; this will prevent 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
22
attached to the casing
prevents accidental touching of the saw blade
during the working procedure and may not be
removed.
The outwardly curved edge over the extraction
hood
16
prevents 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 °.
