Assembly
Replacing/Inserting the Saw Blade
 Before any work on the machine itself, pull the mains
plug.
 When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
 When changing the saw blade, take care that the saw
blade holder is free of material residue, e. g. wood or
metal shavings.
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
beginning of these operating instructions. Use only saw
blades with ½" universal shank. The saw blade should not be
longer than required for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure A)
Press the SDS clamping lever 5 forward and guide the saw
blade 1 behind the clamping plate 12 into the saw blade hold-
er 3. Release the SDS clamping lever 5.
 Check the tight seating by pulling on the saw blade. A
loose saw blade can fall out and cause injury.
For certain work, the saw blade 1 can also be turned through
180° (with the teeth pointed upwards) and re-inserted again.
Removing the Saw Blade
 Before removing, allow the saw blade to cool down.
Danger of injury when touching the hot saw blade.
Press the SDS clamping lever 5 forward and pull out the saw
blade 1. Release the SDS clamping lever 5.
Dust/Chip Extraction
 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.

plug.
Pivoting and Retractable Footplate (see figure B–C)
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.
Depending on the application and the saw blade being used,
the footplate 2 can be moved variably in length direction.
Loosen the screws 13 with Allen key 9 and move the footplate
2 to the requested position. Tighten the screws 13 again and
check if the footplate 2 is tightly seated.
Utility Hook (see figure D)
Your tool is equipped with a utility hook 6 for hanging it, e. g.,
to a ladder, etc. Simply fold out the utility hook 6 to the re-
quired position.
 When the tool is hanging by the utility hook, ensure
that the saw blade is protected against unintended
contact. Danger of injury.
Fold the utility hook 6 back in again when you are ready to
continue working.
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er 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.
The "Power Light" 10 is lit when the mains plug is inserted,
and allows for illumination of the working range under unfa-
vourable light conditions.
