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 mainte-
nance task quickly and reliably.
Aligning the Fence
– Bring the machine into the transport position.
– Turn the saw table 7 to the 0° detent 45. The lever 11 must
be felt to engage in the detent.
– Pull the adjustable fence 17 completely outward.
(see figure G)
Checking: (see figure O1)
– Adjust an angle gauge to 90° and position it flush with the
saw blade 41 between the fence 6 and the saw blade on
the saw table 7.
The leg of the angle gauge must be flush with the fence over
the complete length.
Adjusting: (see figure O2)
– Loosen all hex socket screws 47 with the hex key 22 pro-
vided.
– Turn the fence 6 until the angle gauge is flush over the com-
plete length.
– Retighten the screws again.
Setting the Standard Bevel Angle 0° (Vertical)
– Bring the machine into the transport position.
– Turn the saw table 7 to the 0° detent 45. The lever 11 must
be felt to engage in the detent.
Checking: (see figure P1)
– Set an angle gauge to 90° and place it on the saw table 7.
The leg of the angle gauge must be flush with the saw blade 41
over the complete length.
Adjusting: (see figure P2)
– Loosen the lock lever 26.
– Loosen the lock nut of the stop screw 33 using a commer-
cial box-end or open-end spanner (size 13 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Retighten the lock lever 26 again.
– Afterwards, retighten the lock nut of the stop screw 33
again.
In case the angle indicator 31 is not in a line with the 0° mark
of the scale 32 after the adjustment, loosen the screw 48 us-
ing a commercial cross-head screwdriver and align the angle
indicator along the 0° mark. (see figure R)
Setting the Standard Bevel Angle 45° (Vertical)
– Bring the power tool into the working position.
– Turn the saw table 7 to the 0° detent 45. The lever 11 must
be felt to engage in the detent.
– Loosen the lock lever 26 and tilt the tool arm leftward to
the stop (45°) by the handle 3.
Bosch Power Tools
Checking: (see figure Q1)
– Set an angle gauge to 45° and place it on the saw table 7.
The leg of the angle gauge must be flush with the saw blade 41
over the complete length.
Adjusting: (see figure Q2)
– Loosen the lock nut of the stop screw 23 using a commer-
cial box-end or open-end spanner (size 13 mm).
– Screw the stop screw in or out until the leg of the angle
gauge is flush with the saw blade over the complete length.
– Retighten the lock lever 26 again.
– Afterwards, retighten the lock nut of the stop screw 23
again.
In case the angle indicator 31 is not in a line with the 45° mark
of the scale 32, firstly check the 0° setting for the bevel angle
and the angle indicator again. Then repeat the adjustment of
the 45° bevel angle.
Transport (see figure S)
Before transporting the power tool, the following steps must
be carried out:
– Bring the machine into the transport position.
– 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 28 or hold it by
the recessed handles 15 on the sides of the saw table.
 When transporting the power tool, use only the trans-
port devices and never use the protective devices.

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.
Remove dust and chips after each working procedure by
blowing out with compressed air or with a brush.
