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 hex 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 ac-
cidental touching of the saw blade during the working proce-
dure 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,
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.
Parallel Guide with Circle Cutter (Accessory)
Parallel Cuts (see figure H): Loosen the locking screw
26
and
slide the scale of the parallel guide through the lead
13
in the
base plate. Set the desired cutting width as the scale value on
the inside edge of the base plate. Tighten the locking screw
26
.
