Sawing with Guide Rail (see figures F–H)
The guide rail 28 is used to carry out straight cuts.
The adhesive coating prevents the guide rail from slipping and
protects the surface of the workpiece. The coating of the
guide rail allows the circular saw to glide easily.
For sawing at a right angle, the circular saw can be placed di-
rectly onto the guide rail 28. Fasten the guide rail 28 with suit-
able clamping devices, e. g., screw clamps, on the workpiece
in such a manner that the narrow leg of the guide rail 28 faces
toward the saw blade.
The guide rail 28 must not extend beyond the face side of
the workpiece where the cut is to be started.
The guide-rail adapter 31 is required for bevel cuts with the
guide rail 28. The guide-rail adapter 31 is mounted in the
same manner as the parallel guide 11.
The rubber lip on the guide rail acts as splinter guard and pre-
vents the surface of wooden materials from splitting when
sawed. The saw blade must be positioned with the teeth di-
rectly on the rubber lip for this to work.
The following work steps are required for exact cuts using the
guide rail 28:
– Place the guide rail 28 onto the workpiece projecting light-
ly over the side. Pay attention that the side with the rubber
lip faces to the workpiece.

– Set the circular saw with the premounted guide-rail adapt-
er 31 onto the guide rail 28.
– Adjust the desired cutting depth and the bevel angle. Ob-
serve the marks on the guide-rail adapter 31 for preadjust-
ment of the various bevel angles; see figure F.
– Align the circular saw with guide-rail adapter in such a man-
ner that the teeth of the saw blade 20 face against the rub-
ber lip. The position of the saw blade 20 depends on the
selected cutting angle. Do not saw into the guide rail.

– Tighten wing bolt 8 to lock the position of the guide-rail
adapter.
– Remove the circular saw with the premounted guide-rail
adapter 31 from the guide rail 28.

– Align the guide rail 28 on the workpiece in such a manner
that the rubber lip lies exactly alongside the cutting edge.
– The guide rail 28 must not extend beyond the face side
of the workpiece where the cut is to be started.
– Fasten the guide rail 28 with suitable clamping devices,
e. g., screw clamps, on the workpiece. Set the circular saw
with the premounted guide-rail adapter 31 onto the guide
rail.
– Switch the power tool on and guide it in the cutting direc-
tion applying moderate and steady feed.
Two guide rails can be connected to one with use of the con-
nection piece 29. Clamping is carried out with the four screws
located in the connection piece.

Maintenance and Cleaning

 Before any work on the power tool itself, pull the mains
plug.
 For safe and proper working, always keep the power
tool and the 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 by blowing out with compressed air or with a brush.
Saw blades that are not coated can be protected against cor-
rosion with a thin coat of acid-free oil. Before use, the oil must
be removed again, otherwise the wood will become soiled.
Resin and glue residue on the saw blade produces poor cuts.
Therefore, clean the saw blade immediately after use.
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.
