(8 mm) until the leg of the angle gauge is flush with the saw
blade over the complete length.
– Retighten the lock lever 17 again.
When the angle indicators 33 and 24 are not in line with the
45° marks of scale 32 after adjusting, firstly once more check
the 0° setting for the bevel angle and the angle indicators.
Then repeat the adjustment of the 45° bevel angle.
Setting the Standard 45° Bevel Angle (Rightward)
– Bring the power tool into the working position.
– Turn the saw table 38 to the 0° detent 18. The lever 16
must be felt to engage in the detent.
– Pull the right fence extension 9 completely outward.
– Loosen the lock lever 17.
– Lightly tilt the glide arm leftward out of the 0°
position via handle 4 and turn rotary knob 39
until the righthand bevel angle range is indicat-
ed.
– Tilt the glide arm via handle 4 rightward to the stop (45°).
Checking: (see figure W1)
– Set an angle gauge to 135° and place it on the saw table
38.
The leg of the angle gauge must be flush with the saw blade
40 over the complete length.
Adjusting: (see figure W2)
– Screw set screw 72 in or out with an open-end spanner
(8 mm) until the leg of the angle gauge is flush with the saw
blade over the complete length.
– Retighten the lock lever 17 again.
When the angle indicators 33 and 24 are not in line with the
45° marks of scale 32 after adjusting, firstly once more check
the 0° setting for the bevel angle and the angle indicators.
Then repeat the adjustment of the 45° bevel angle.
Aligning the Scale for Mitre Angles
– Bring the power tool into the working position.
– Turn the saw table 38 to the 0° detent 18. The lever 16
must be felt to engage in the detent.
Checking: (see figure X1)
– Adjust an angle gauge to 90° and position it between the
fence 10 and the saw blade 40 on the saw table 38.
The leg of the angle gauge must be flush with the saw blade
40 over the complete length.
Adjusting: (see figure X2)
– Loosen all four set screws 73 with the hex key (4 mm) 20
and turn the saw table 38 together with the scale 37 until
the leg of the angle gauge is flush with the saw blade over
the complete length.
– Retighten the screws again.
When the angle indicator 59 is not in line with the 0° mark of
scale 37 after adjusting, loosen screw 74 with a cross-head
screwdriver and align the angle indicator alongside the
0° mark.

Adjusting the Clamping Force of Lock Lever 17
(see figure Y)
The clamping force of lock lever 17 can be readjusted.
Checking:
– The clamping force of the lock lever must securely hold the
position of the glide arm at any bevel angle.
Adjusting:
– Loosen the lock lever 17.
– Turn set screw 75 in anticlockwise direction with a socket
spanner (size 17 mm) to reduce the clamping force, or in-
crease the clamping force by turning in clockwise direction.
– Adjust a vertical bevel angle, retighten lock lever 17 and
check if the desired clamping force has been reached.
Transport (see figure Z)
Before transporting the power tool, the following steps must
be carried out:
– Slide glide arm 28 completely to the rear and secure it in
this position (see "Securing the Glide Arm", page 38).
– Make sure that the depth stop 30 is pushed completely in-
ward and that adjusting screw 29 fits through the recess
without touching the depth stop when moving the glide arm.
– Guide the glide arm downward until transport safety-lock
31 can be pushed completely inward.
– Slide the table extensions 11 completely inward.
– Set the vertical bevel angle to 0° and tighten the lock lever
17.
– Turn saw table 38 leftward to the stop and tighten locking
knob 15.
– Wind up the mains cable and tie it together with Velcro
strap 76.
– Remove all accessories that cannot be mounted firmly to
the power tool.
If possible, place unused saw blades in an enclosed con-
tainer for transport.
– Carry the machine by the transport handle 7 or hold it by
the recessed handles 19 on the sides of the saw table.
 When transporting the power tool, only use the trans-
port fixtures. Never carry the power tool by the protec-
tive devices, the glide arm 28 or the handle 4.
 The power tool should always be carried by two per-
sons in order to avoid back injuries.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself, pull the mains
plug.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Cleaning
For safe and proper working, always keep the power tool and
its ventilation slots clean.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean.
