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 23 and all clamping parts to
be assembled.
– Tilt back the retracting blade guard 21 and hold
firmly.
– Place the saw blade 23 onto the mounting flange
22. The cutting direction of the teeth (direction of
arrow on the saw blade) and the direction-of-ro-
tation arrow on the retracting blade guard 21
must correspond.
– Mount the clamping flange 24 and screw in the
clamping bolt 25 turning in rotation direction .
Observe correct mounting position of mounting
flange 22 and clamping flange 24.
– Press the spindle lock button 6 and keep it
pressed.
– With the Hex key 5, tighten the clamping bolt 25
turning in rotation direction . The tightening
torque is between 6–9 Nm, which corresponds
to hand tight plus ¼ turn.

Dust/Chip Extraction

 Before any work on the power tool, remove the
battery.
 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 reac-
tions 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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– To achieve a high level of dust extraction, use
a suitable dust extractor together with this
power tool.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.
Mounting the Extraction Adapter (see figure B)
Fasten the extraction adapter 29 to the base plate
7 with the fastening screw 28.
A vacuum hose with a diameter of 19 mm can be
connected to the extraction adapter 29.
 The extraction adapter may not be mounted
when no external dust extraction is connect-
ed. Otherwise the extraction channel can be-
come clogged.
20 | English
 Do not connect a dust bag to the extraction
adapter. Otherwise the extraction system can
become clogged.
To ensure optimum extraction, the extraction
adapter 29 must be cleaned regularly.
External Dust Extraction
Connect vacuum hose 30 via adapter 29 (accesso-
ry) to the vacuum hose of a vacuum cleaner (acces-
sory).
The vacuum cleaner must be suitable for the mate-
rial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special vac-
uum cleaner.
Operation

Operating Modes

 Before any work on the power tool, remove the
battery.
Adjusting the Cutting Depth (see figure C)
 Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the
blade teeth should be visible below the work-
piece.
Loosen wing bolt 17. For a smaller cutting depth,
pull the machine from the base plate 7; for a larger
cutting depth, push the machine toward the base
plate 7. Adjust the desired cutting depth at the cut-
ting-depth scale 18. Tighten wing bolt 17 again.
When setting the cutting depth, use the reference
mark 31 to the side of the cutting-depth scale 18.
Adjusting the Cutting Angle
It is best to place the machine on the face side of
the blade guard 13.
Loosen wing bolt 10. Tilt the saw sidewards. Adjust
the desired setting at the scale 9. Tighten wing bolt
10 again.
When setting the mitre angle, use the reference
mark 27 (upper edge of the holder).
Note: For bevel cuts, the cutting depth is smaller
than the setting indicated on the cutting-depth
scale 18.
Cutting Marks
The 0 ° cutting mark 12 indicates the position of the
saw blade for right-angled cuts. The 45 ° cutting
mark 11 indicates the position of the saw blade for
45 ° cuts.
