– Switch off the machine and wait until the saw blade has
come to a complete stop.
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.
Adjusting the Clearance Indicator of the Parallel Guide
(see figure G)
– Use a workpiece or an object with an exactly defined width
x. The length of the object should approximately corre-
spond with the diameter of the saw blade.
– Slide the object under the blade guard 63 and position it
flush to the saw blade.
– Move the parallel guide 61 from the right side until it touch-
es the object, and then lock the parallel guide in this posi-
tion.
Checking:
The clearance indicator 69 must indicate the width x of the
object on the scale 65.
Adjusting:
– Loosen screw 70 with the slotted screwdriver provided
and align the clearance indicator exactly to the width x.
Adjusting the Tension Force of the Parallel Guide
(see figure H)
The tension force of the guide 71 on the parallel guide can de-
crease after frequent use.
– Tighten the adjustment screw 72 until the parallel guide
can be firmly affixed on the saw table again.
Aligning the Parallel Guide Parallel to the Saw Blade
– Use a workpiece or an appropriate object with parallel edg-
es. The length of the object should approximately corre-
spond with the diameter of the saw blade.
– Slide the object under the blade guard 63 and position it
flush to the saw blade.
– Move the parallel guide 61 from right to left until it touches
the object.
Checking: (see figure
The parallel guide must be flush with the object over the com-
plete length.
Adjusting:
– Remove the parallel guide from the saw table 59 and loos-
en the three screws 73 inside the glide pad of the parallel
guide using a Phillips screwdriver. (see figure
– Press the parallel guide from the front firmly against the
scale 65 and align it flush alongside the object on the saw
table. (see figure

– Hold the parallel guide in this position and tighten the left
and right set screw 74 with the slotted screwdriver provid-
ed. (see figure
– Remove the parallel guide from the saw table.
– Screw the centre set screw 74 in or out until it is flush with
the glide pad surface.
– Hold the respective position of each set screw and tighten
all screws 73 again. (see figure
If the parallel guide can no longer be firmly attached onto the
saw table after aligning, reset the tensioning force of the guide
71. (see "Adjusting the Tension Force of the Parallel Guide",
page 48)

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.
Clean the lighting and laser unit (34, 19) regularly.
To clean the laser lens cover 16, completely unscrew the
screw. Afterwards, pull the cover out of the casing alongside
the retracting blade guard 20. (see figure h)
