When sawing profiles, always begin the cut from the narrow
side; when sawing U-profiles, never start the cut from the
open side. Support long profiles in order to avoid blade bind-
ing and kickback of the power tool.
Sawing Light Building Materials (Materials with Mineral
Content) (GKS 55 GCE)
 When sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
Light building materials may only be sawn dry and when ap-
plying dust extraction. Always work with the guide rail 29 (ac-
cessory).
The vacuum cleaner must be approved for the extraction of
masonry dust. Bosch provides suitable vacuum cleaners.
Sawing with Parallel Guide (see figure D)
The parallel guide 12 enables exact cuts along a workpiece
edge and cutting strips of the same dimension.
Loosen wing bolt 7 and slide the scale of the parallel guide 12
through the guide in the base plate 15. Adjust the desired cut-
ting width as the scale setting at the respective cutting mark 9
or 10; see Section "Cutting Marks". Tighten wing bolt 7 again.
Sawing with Auxiliary Guide (see figure E)
For sawing large workpieces or straight edges, a board or
strip can be clamped to the workpiece as an auxiliary guide;
the base plate of the circular saw can be guided alongside the
auxiliary guide.
Sawing with Guide Rail (GKS 55 GCE) (see figure F–G)
The guide rail 29 is used to carry out straight cuts.
The rubber lip on the guide rail acts as a splinter guard; it pre-
vents fraying of the surface while sawing wooden materials.
For this, the teeth of the saw blade must face directly against
the rubber lip.
Prior to the very first cut, the rubber lip must be adapted with
the guide rail 29 to the circular saw being used. For this, place
the guide rail 29 over its complete length on a workpiece. Ad-
just a cutting depth of approx. 9 mm and the saw blade to a ze-
ro degree angle. Switch the circular saw on and guide it uni-
formly and with light feed in the cutting direction.
Two guide rails can be connected using the connection piece
30. Clamping is carried out with the four screws located in the
connection piece.
Maintenance and Service
Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and 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.
Bosch Power Tools
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.
