Operating Modes
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.
Orbital Action Settings
The adjustable orbital action allows for optimal adaptation of
cutting speed, cutting capacity and cutting pattern to the mate-
rial being worked.
The orbital action can be adjusted with the adjusting lever
8
,
even during operation.
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 H)
The base plate
9
can be swivelled by 45° to the left or right
for mitre cuts.
Remove the vacuum connection
18
.
In mitre angle 0° there is a pin in a corresponding recess.
Loosen the screw
23
with the hex key
24
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
angle can be adjusted to 45° using a protractor.
Tighten the screw
23
again.
The vacuum connection
18
and the splinter guard
14
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 handle until it can be felt
to engage and faces flush against the handle.
Switching On and Off
To
start
the machine, push the On/Off switch
7
forward so
that the “
I
” is indicated on the switch.
To
switch off
the machine, push the On/Off switch
7
toward the rear so that the “
0
” is indicated on the switch.
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
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 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.
Orbital action switched off
(level 0):
No orbital action
Orbital action level I:
Small orbital action
Orbital action level II:
Large orbital action
