4. Operating instructions
4.1 Colocación y pruebas
Check the electroBtool for possible damage.
Before further use of the electro-tool, check that all the
protective devices are fully functional. Any lightly damaged
parts must be carefully checked to ensure flawless
operation of the tool. All parts must be properly mounted
and all conditions fulfilled that ensure faultless operation.
Damaged protective devices and parts must be
immediately replaced by an authorised service centre.
Checking and Adjusting the Basic Adjustment
Before any work on the machine itself, pull the
mains plug.
To ensure precise cuts, the basic adjustment of the
machine must be checked and adjusted as necessary
after intensive use.
A certain level of experience and appropriate specialty
tools are required for this.
A Bosch after-sales service station will handle this
maintenance task quickly and reliably.
Setting the Standard Bevel Angle 0° (Vertical)
– Bring the machine into the transport position.
– Turn the saw table 5 to the 0° detent. The lever 6 must
be felt to engage in the detent.
Checking:
– Set an angle gauge to 90° and place it on the saw table
5. The leg of the angle gauge must be flush with the
saw blade 7 over the complete length.
- To adjust to zero, act on 13.
- To adjust to 45º act on 43.
Setting the Standard 45° Bevel Angle (Leftward)
- Bring the power tool into the working position.
- Turn the saw table to the 0° detent. The lever must be
felt to engage in the detent.
- Pull the left fence extension completely outward.

– Loosen the lock lever and tilt the tool arm leftward to
the stop (45°) by the handle .
Checking:
– Set an angle gauge to 45° and place it on the saw table
16.
The leg of the angle gauge must be flush with the saw
blade over the complete length.
4.2 Changing the Tool
- 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.
Use only saw blades whose maximum permitted speed is
higher than the no-load speed of the power tool.
Use only saw blades that correspond with the characteristic
data given in these operation instructions and that are
tested and marked in accordance with EN 847-1.
Use only saw blades recommended by the tool
manufacturer, and suitable for sawing the materials to
be cut. This prevents overheating of the saw teeth during
sawing.
Removing the Saw Blade.
– Bring the power tool into the working position.
– Loosen the screws 34 and 35 with the provided
crosshead screwdriver 35.
Do not completely unscrew the screws.
– Push the locking lever 25 and swing the retracting blade
guard 1 to the rear to the stop.
– Turn hexagon bolt 36 with the supplied socket spanner
32 and at the same time press the spindle lock 19 until it
engages.
– Keep the spindle lock 19 pressed and unscrew hexagon
bolt 36 in clockwise direction (left-hand thread!).
– Remove the clamping flange 37.
– Remove the saw blade 2.
Mounting the Saw Blade
If required, clean all parts to be mounted prior to assembly.
– Place the new saw blade onto the interior clamping
flange 38.
- Take care during the mounting that the cutting
direction of the teeth (direction of the arrow on the
saw blade) agrees with the direction of the arrow on
the retracting blade guard!
– Mount the clamping flange 37 and the hexagon bolt 36.
Press spindle lock 19 until it engages and tighten hexagon
bolt 36with the supplied socket spanner 32 in anticlockwise
direction with a tightening torque of approx. 15–23 Nm.
– Push the locking lever 19 and guide the retracting blade
guard 1 down again.
