The cutting mark 0° (8) indicates the position of
the saw blade for right-angled cuts. The cutting
mark 45° (7) indicates the position of the saw
blade for 45° cuts. The maximum tooth width of
saw blade should be taken into consideration
according to tool specifications. Both cutting
marks include the width of the saw blade.
Always guide the saw blade off of the drawn-up
cutting line so that the required measure is not
reduced by the width of the saw blade. For this,
choose the corresponding notch side of the
cutting mark 0° (8) or 45° (7) as shown in the
illustration.
Note: It is best to carry out a trial cut.
Changing the Tool (see figure A )
• Wear protective gloves
• Disconnect the plug from the power source
before making any assembly, adjustments or
changing accessories. Such preventive safety
measures reduce the risk of starting the tool
accidentally.
• Only use saw blades that correspond with
the characteristic data given in the operating
instructions.
• Do not under any circumstances use grinding
discs as the cutting tool.
For changing the cutting tool, it is best to place
the machine on the face side of the motor housing.
Removing
Press the spindle lock button 3 and keep it depressed.
• The spindle lock button 3 may be actuated
only when the saw blade is at a standstill.
Unscrew clamping bolt 19 with the Allen key 20.
Remove clamping flange 18.
Tilt back the retracting blade guard 10 and hold
firmly.
Remove the saw blade.
Mounting
• Clean the saw blade and all the clamping
parts to be assembled.
Tilt back the retracting blade guard 10 and hold
firmly. Place the saw blade onto the mounting
flange 16. Assemble the clamping bolt 19 and
the clamping flange 18. Tighten the clamping
bolt 19 with the Allen key 20. Tightening torque:
6 – 9 Nm; equivalent to hand-tight plus 1/4 turn.
Take care that the mounting positions of the
mounting flange 16 and clamping flange 18 are
correct. When mounting: Ensure that the cutting
direction of the teeth (direction of arrow on saw
blade) and the direction- of-rotation arrow on
the blade guard match.
Dust/Chip Extraction
Mounting the Extraction Adapter (Accessory
see figure G )
Fasten the extraction adapter 24 onto the
sawdust ejector 13 until it latches. Additionally
fasten the extraction adapter to the blade guard
14 with the screw (see figure).
Directly connect a 35 mm Ø vacuum hose to the
extraction adapter.
• The extraction adapter must not be mounted
when no external dust extraction is
connected. Otherwise there is danger of the
extraction channel becoming clogged.
• A dust bag must not be connected to the
extraction adapter. Otherwise there is danger
of the extraction system becoming clogged.
Clean the extraction adapter regularly to ensure
optimum dust extraction. The machine can be
plugged directly into the receptacle of a Bosch
all-purpose vacuum cleaner with remote starting
control. The vacuum cleaner starts automatically
when the machine is switched on.
The vacuum cleaner must be suitable for the
material to be worked.
When vacuuming dry dust that is especially
detrimental to health or carcinogenic, use a
special vacuum cleaner.
Operating Instructions
• Protect saw blades against impact and shock.
Excessive feed significantly reduces the
performance capability of the machine and
reduces the service life of the saw blade.
Sawing performance and cutting quality depend
essentially on the condition and the tooth form
of the saw blade. Therefore, use only sharp saw
blades that are suited for the material to be
worked. The correct selection of the saw blade
depends on the type and quality of the wood
and whether lengthway or crossway cuts are required.
When cutting spruce lengthways, long
spiral chips are formed. Beech and oak dusts are
especially detrimental to health. Therefore, work
only with dust extraction.
Tips
Parallel Guide (see figure E )
The parallel guide 9 enables exact cuts along a
workpiece edge and cutting strips of the same
dimension.

•
The lower guard should be retracted manually on-
ly for special cuts such as “plunge cuts” and “com-
pound cuts”. Raise the lower guard with the retract-
ing handle and as soon as blade enters the material,
the lower guard must be released.
For all other sawing,
the lower guard must operate automatically.
•
Always observe that the lower guard is covering the
saw blade before placing down the saw on a work-
bench or the floor.
An unprotected, coasting blade will
cause the saw to travel backwards, cutting whatever is in its
path. Be aware of the run-on period of the saw.
•
Do not reach into the saw dust ejector with your
hands.
They could be injured by rotating parts.
•
Do not work overhead with the saw.
In this manner you
do not have sufficient control over the power tool.
•
Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility com-
pany for assistance.
Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property damage
or may cause an electric shock.
•
Do not operate the power tool stationary.
It is not de-
signed for operation with a saw table.
•
Do not use high speed steel (HSS) saw blades.
Such
saw blades can easily break.
Starting Operation
Observe correct mains voltage: The voltage of the power
source must agree with the voltage specified on the name-
plate of the machine.
Equipment marked with 230V can also be connected to
220V.
Switching On and Off
For starting operation of the machine, actuate the lock-off
button 2 first, and then press and hold the On/Off switch 1
afterwards.
To switch off the machine, release the On/Off switch 1.
For safety reasons the On/Off switch of the machi-
ne cannot be locked; it must remain pressed du-
ring the entire operation.
Adjusting the Cutting Depth (see figure
B
)
• Before any work on the machine itself, pull the mains
plug.
To achieve an optimum cut, the saw blade must not
protrude the material by more than 3 mm or one tooth (max-
imum). See figure
C
.
To adjust the cutting depth, loosen winged screw 21 and
raise the saw from the base plate 11 or lower it towards the
base plate, respectively:
Raise
→
for smaller cutting depths
Lower
→
for greater cutting depths
Retighten the winged screw 21.
Adjusting the Cutting Angle
• Before any work on the machine itself, pull the mains
plug.
Loosen the winged screws 6.
It is best to place the machine on the face side of the blade
guard.
Tilt the base plate away from the machine until the required
cutting angle is adjusted on the cutting angle scale 4.
Tighten the winged screws again.
