Checking and adjusting the basic settings
To ensure precise cuts, the basic settings of the power tool must be checked and adjusted as necessary after intensive use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work quickly and reliably.
- Bring the power tool into the work position.
- Set the saw blade to a bevel angle of 0°.
- Remove the blade guard (3).
Checking (see figure J1)
- Set an angle gauge to 90° and place it on the saw table (2).
The leg of the angle gauge must be flush with the saw blade (28) along its entire length.
Setting (see figure J2)
- Loosen the lock nut of the stop screw (17) using a commercially available box-ended or open-ended spanner.
- Loosen the locking lever (19).
- Push the handwheel (18) against the stop screw (17) and turn the stop screw as far in or out as needed until the leg of the angle gauge is flush with the saw blade along its entire length.
- Hold the hand wheel in this position and retighten the locking lever (19).
- Retighten the lock nut of the stop screw (17).
If the angle indicator (56) is not aligned with the 0° mark on the scale (21) following adjustment, loosen the screw (60) using a commercially available cross-headed screwdriver and align the angle indicator along the 0° mark.
Repeat the above work steps for the bevel angle of 45° (loosen the lock nut; adjust the stop screw (22)). The angle indicator (56) must not be repositioned when doing this.
- Bring the power tool into the work position.
- Remove the blade guard (3).
Checking
- Use a pencil to mark the first left-hand saw tooth that is visible at the back above the table insert.
- Set an angle gauge to 90° and place it on the edge of the guide groove (47).
- Move the leg of the angle gauge until it touches the marked saw tooth and read the distance between the saw blade and the guide groove.
- Turn the saw blade until the marked tooth at the front lies above the table insert.
- Move the angle gauge along the guide groove up to the marked saw tooth.
- Measure the distance between the saw blade and the guide groove again.
The two measured distances must be identical.
Setting
- Loosen the hex socket screws (61) at the front beneath the saw table and the hex socket screws (62) at the rear beneath the saw table using the hex key (9) provided.
- Carefully move the saw blade until it lies parallel with the guide groove (47).
- Retighten all screws (61) and (62).
Before aligning the parallel guide (27), you must first adjust the stops (17)/(22) for the standard bevel angles and ensure that the saw blade (28) is parallel with the guide grooves (47) of the angle guide.
see Adjusting the stops for a standard bevel angle 0°/45°
see Parallelism of the saw blade with the guide grooves of the angle guide (see figure K)
- Loosen the locking levers (42) on the parallel guide (27) and allow the parallel guide to move freely during the entire aligning process.
- Position the notches on the parallel guide (27) above pin pair (44) (silver). The folding additional parallel stop (8) must be facing away from the protective cover (3).
- Remove the protective cover (3).
- Pull the clamping handle (25) for the saw table expansion all the way up and reposition the parallel guide (27) until it is touching the saw blade (28).
Checking
The parallel guide (27) must touch the saw blade along its entire length.
Adjusting
- Loosen the silver screws of the pin pair (44) with the supplied hex key (9) enough so that the pins can glide freely.
- Use the parallel guide (44) to push the pin pair (27) approx. 3 mm to the right.
- Use the rotary knob (24) on the upper, silver scale (13) to set a spacing of 0 mm between the parallel guide and the saw blade.
- Push the clamping handle (25) for the saw table expansion down.
- Use the parallel guide (27) to push the pin pair (44) to the left until the parallel guide is touching the saw blade along its entire length.
- Carefully tighten the silver screws of the pin pair (44) using the supplied hex key (9).
- Fold the locking levers (42) down on both sides to fix the parallel guide in place.
- Make sure that the parallel guide is still touching the saw blade along its entire length after tightening.
Then check black pin pairs (43) and (45).
Before aligning pin pair (43), you first need to align pin pair (44) (silver, right) correctly.
see Aligning the Parallel Guide – Pin Pair (44), Silver, Right (see figure L)
- Loosen the locking levers (42) on the parallel guide (27) and lift the parallel guide off the pin pair (44).
- Loosen the black screws of pin pair (43) with the supplied hex key (9) such that the pins can glide freely.
- Hold the recesses of the ring spanner (23) against the front pins (44)/(43).
- Move the black pin (43) until the two pins (silver (44) and black (43)) fit in the relevant recess of the ring spanner.
- Repeat these actions with the rear pins (44)/(43).
Before aligning the parallel guide (27), you must first adjust the stops (17)/(22) for the standard bevel angles and ensure that the saw blade (28) is parallel with the guide grooves (47) of the angle guide.

- Loosen the locking levers (42) on the parallel guide (27) and allow the parallel guide to move freely during the entire aligning process.
- Position the notches on the parallel guide (27) above pin pair (45) (black). The folding additional parallel stop (8) must be facing away from the protective cover (3).
- Remove the protective cover (3).
- Pull the clamping handle (25) for the saw table expansion all the way up and reposition the parallel guide (27) until it is touching the saw blade (28).

- Retighten the screws (63).
