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.
Note: To test the laser function, the power tool must be connected to the power supply.
- While adjusting the laser (e.g. when moving the tool arm), never activate the on/off switch. Starting the power tool accidentally can lead to injuries.
- Bring the power tool into the work position.
- Turn the saw table (37) to the 0° detent (14). The lever (12) must be felt to engage in the detent.
Checking (see figure T1)
- Draw a straight cutting line on the workpiece.
- Slowly guide the glide arm (27) downwards using the handle (1).
- Position the workpiece so that the teeth of the saw blade line up with the cutting line.
- Hold the workpiece in this position and slowly guide the glide arm upwards.
- Clamp the workpiece.
- Switch on the laser beams with the switch (59).
The laser beams must be the same distance away (left and right) from the cutting line marked on the workpiece along their entire length, even when lowering the glide arm.
Removing the laser protection cap (see figure T2)
- Loosen the two screws (62) on the laser protection cap (26) using the hex key (4 mm) (16).
Note: To access the front screw on the laser protection cap, the glide arm must be swivelled down slightly until the hex key can be inserted through one of the slots on the retracting blade guard.
Adjusting the flush alignment (see figure T3)
- Remove the laser protection cap (26).
1. Adjusting the right-hand laser beam:
- Turn the rear set screw (63) using the hex key (17) until the entire length of the right-hand laser beam is flush with the cutting line marked on the workpiece.
This also moves the left-hand laser beam.
One rotation anticlockwise moves the laser beam from left to right; one rotation clockwise moves the laser beam from right to left.
2. Adjusting the left-hand laser beam:
- Turn the front set screw (63) using the hex key (17) until the left-hand laser beam is the same distance away from the cutting line marked on the workpiece as the right-hand laser beam.
One rotation anticlockwise moves the laser beam from left to right; one rotation clockwise moves the laser beam from right to left.
- Reattach the laser protection cap (26).
Adjusting the parallelism (see figure T4)
- Remove the laser protection cap (26).
- Loosen the fastening screw (64) (by approx. 1–2 turns) using the hex key (17). Do not unscrew the screw completely.
- Move the laser mounting plate to the right or left until the laser beams are parallel with the marked cutting line on the workpiece along their entire length.
- Hold the laser mounting plate in this position and retighten the fastening screw (64).
- Check the flush alignment with the cutting line again following adjustment. If required, use the set screws (63) to align the laser beams again.
- Reattach the laser protection cap (26).
Adjusting the side deviation when moving the glide arm (see figure T5)
- Remove the laser protection cap (26).
- Loosen the two fastening screws (65) (by approx. 1–2 turns) using the hex key (17).
Do not completely unscrew the screws. - Move the laser housing to the right or left until the laser beams no longer deviate at the sides when moving the glide arm down.
- Check the flush alignment with the cutting line again following adjustment. If required, use the set screws (63) to align the laser beams again.
- Hold the laser housing in this position and retighten the fastening screws (65).
- Reattach the laser protection cap (26).
- Bring the power tool into the transport position.
- Turn the saw table (37) to the 0° detent (14). The lever (12) must be felt to engage in the detent.
Checking (see figure U1)
- Set an angle gauge to 90° and place it on the saw table (37).
The leg of the angle gauge must be flush with the saw blade (39) along its entire length.
Setting (see figure U2)
- Loosen the clamping handle (13).
- Loosen the two set screws (66) (by at least one turn) using a socket spanner (10 mm).
- Loosen the set screw (68) (by approx. three turns) using the hex key (4 mm) (16).
- Tighten or loosen the set screw (67) using the hex key (4 mm) (16) until the leg of the angle gauge is flush with the saw blade along its entire length.
- Retighten the clamping handle (13). Then tighten the set screw (68) followed by the set screws (66).
If the angle indicators (32) and (20) are not in line with the 0° marks on the scale (31) following adjustment, loosen the fastening screws on the angle indicators using a cross-headed screwdriver and align the angle indicators with the 0° marks.
- Bring the power tool into the work position.
- Turn the saw table (37) to the 0° detent (14). The lever (12) must be felt to engage in the detent.
- Pull the left-hand adjustable fence (5) all the way out.
- Loosen the clamping handle (13) and swivel the glide arm to the left stop (45°) by the handle (1).
Checking (see figure V1)
- Set an angle gauge to 45° and place it on the saw table (37).
The leg of the angle gauge must be flush with the saw blade (39) along its entire length.
Setting (see figure V2)
- Tighten or loosen the set screw (69) using an open-ended spanner (8 mm) until the leg of the angle gauge is flush with the saw blade along its entire length.
- Retighten the clamping handle (13).
If the angle indicators (32) and (20) are not in line with the 45° marks on the scale (31) following adjustment, first check the 0° setting for the bevel angle and the angle indicators once more. Then repeat the adjustment of the 45° bevel angle.
- Bring the power tool into the work position.
- Turn the saw table (37) to the 0° detent (14). The lever (12) must be felt to engage in the detent.
- Pull the right-hand adjustable fence (5) all the way out.
- Loosen the clamping handle (13).

- Swivel the glide arm to the right stop (45°) by the handle (1).
Checking (see figure W1)
- Set an angle gauge to 135° and place it on the saw table (37).
The leg of the angle gauge must be flush with the saw blade (39) along its entire length.
Setting (see figure W2)
- Tighten or loosen the set screw (70) using an open-ended spanner (8 mm) until the leg of the angle gauge is flush with the saw blade along its entire length.
- Retighten the clamping handle (13).
If the angle indicators (32) and (20) are not in line with the 45° marks on the scale (31) following adjustment, first check the 0° setting for the bevel angle and the angle indicators once more. Then repeat the adjustment of the 45° bevel angle.
- Bring the power tool into the work position.
- Turn the saw table (37) to the 0° detent (14). The lever (12) must be felt to engage in the detent.
Checking (see figure X1)
- Set an angle gauge to 90° and position it between the fence (6) and the saw blade (39) on the saw table (37).
The leg of the angle gauge must be flush with the saw blade (39) along its entire length.
Setting (see figure X2)
- Loosen all four set screws (71) using the hex key (4 mm) (16) and turn the saw table (37) together with the scale (36) until the leg of the angle gauge is flush with the saw blade along its entire length.
- Re-tighten the screws again.
If the angle indicator (57) is not aligned with the 0° mark on the scale (36) following adjustment, loosen the screw (72) using a cross-headed screwdriver and align the angle indicator along the 0° mark.
The clamping force of the clamping handle (13) can be adjusted.
Checking
- The clamping force of the clamping handle must hold the glide arm securely in place at any bevel angle.
Setting
- Loosen the clamping handle (13).
- Use a socket spanner (17 mm) to turn the set screw (73) anticlockwise to reduce the clamping force or clockwise to increase the clamping force.
- Set a bevel angle, retighten the clamping handle (13) and check whether the required clamping force has been reached.
