Ejecting the Saw Blade (see figure A)
Turn the SDS lever 3 by approx. 180° in clock-
wise direction and pull out the saw blade 1.
Dust/Chip Extraction
f Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Operation
Operating Modes
f Before any work on the machine itself, pull
the mains plug.
Turning the Rotating Collar (see figure B)
For certain jobs, the rotating collar 7 can be
turned. Push the release button for the collar 8
to the rear and turn the rotating collar 7 to the
required position.
The position of the rotating collar 7 can be
locked in 90° steps. For this, turn the rotating
collar 7 until the mark on the rotating collar 7 is
in alignment with the mark on the release but-
ton 8. Push the release button for the collar 8 to-
ward the front.
Pivoting Footplate (see figure C)
Due to its movability, the adjustable footplate 2
adapts to the required angular position of the
surface.
Utility Hook (see figure D)
Your tool is equipped with a utility hook 9 for
hanging it, e. g., to a ladder, etc. Simply fold out
the utility hook 9 to the required position.
f When the tool is hanging by the utility hook,
ensure that the saw blade is protected
against unintended contact. Danger of inju-
ry.
Fold the utility hook 9 back in again when you
are ready to continue working.
Starting Operation
f Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, press the On/Off switch
10 and keep it depressed.
To switch off the machine, release the On/Off
switch 10.
Controling the Stroke Rate
Increasing or reducing the pressure on the
On/Off switch 10 enables stepless stroke-rate
control of the switched-on machine.
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.
