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 6 and keep it pressed.
The spindle lock button 6 may be actuated only when
the saw spindle is at a standstill. Otherwise, the power
tool can be damaged.
– With the hex key 5, unscrew the clamping bolt 25 turning
in rotation direction .
– Tilt back the retracting blade guard 21 and hold firmly.
– Remove the clamping flange 24 and the saw blade 23 from
the saw spindle 20.
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 assem-
bled.
– 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-rotation arrow on the retract-
ing 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.
Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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 respirator.
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.
1 609 92A 2CZ | (14.7.16)
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 29
must be cleaned regularly.
External Dust Extraction
Connect the vacuum hose 30 to a vacuum cleaner (accesso-
ry). An overview for connecting to various vacuum cleaners
can be found at the end of this manual.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum 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 work-
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
Loosen wing bolt 17. For a smaller cutting depth, pull the ma-
chine from the base plate 7; for a larger cutting depth, push
the machine toward the base plate 7. Adjust the desired cut-
ting depth at the cutting-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 de-
sired setting at the scale 9. Tighten wing bolt 10 again.
When setting the mitre angle, use the reference mark 27 (up-
per edge of the holder).
Note: For bevel cuts, the cutting depth is smaller than the set-
ting 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.
Starting Operation
Inserting the battery
Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Insert the charged battery 1 from the front into the base of the
power tool. Push the battery completely into the base until
the red stripe can no longer be seen and the battery is secure-
ly locked.
