Selecting a Saw Blade
An overview of recommended saw blades can be found at the
end of this manual.
Removal of the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
– Press the spindle lock button 4 and keep it pressed.
The spindle lock button 4 may be actuated only when
the saw spindle is at a standstill. Otherwise, the power
tool can be damaged.
– With the Allen key 17, unscrew the clamping bolt 18 turn-
ing in rotation direction .
– Tilt back the retracting blade guard 11 and hold firmly.
– Remove the clamping flange 19 and the saw blade 20 from
the saw spindle 22.
Mounting the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
– Clean the saw blade 20 and all clamping parts to be assem-
bled.
– Tilt back the retracting blade guard 11 and hold firmly.
– Place the saw blade 20 on to the mounting flange 21. The

Dust/Chip Extraction
Before any work on the machine itself, pull the mains
plug.
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.
– As far as possible, use a dust extraction system suita-
ble for the material.
– 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.
Mounting the Extraction Adapter (see figure B)
Attach the extraction adapter 23 onto the sawdust ejector 14
until it latches. A vacuum hose with a diameter of 35 mm can
be connected to the extraction adapter 23.
The extraction adapter may not be mounted when no
external dust extraction is connected. Otherwise the ex-
traction channel can become clogged.
Do not connect a dust bag to the extraction adapter.
Otherwise the extraction system can become clogged.
To ensure optimum extraction, the extraction adapter 23
must be cleaned regularly.
