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
end of these instructions. Use only ½" universal shank saw
blades. The saw blade should not be longer than required for
the intended cut.
The shank thickness of the saw blade must be 0.8–1.6 mm.
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 8 into the saw blade holder
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.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
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.
Switching On and Off
To start the machine, press the On/Off switch 6 and keep it
pressed.
To switch off the machine, release the On/Off switch 6.
Note: For safety reasons, the On/Off switch 6 cannot be
locked; it must remain pressed during the entire operation.
To save energy, only switch the power tool on when using it.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 6
enables stepless stroke-rate control of the switched-on ma-
chine.
Light pressure on the On/Off switch 6 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
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. Allow the machine to cool down by
running it for approx. 3 minutes at maximum stroke rate.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
Tips
 When sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
