Speed preselection (GKS 65 GCE)
The required speed can be preselected with the thumbwheel
3 (also while running).
The required speed depends on the saw blade being used and
on the material being worked (see overview of saw blades at
the end of these operating instructions).
Working Advice
Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the cutting di-
rection. Excessive feed significantly reduces the service life of
the saw blade and can cause damage to the power tool.
Sawing performance and cutting quality depend essentially
on the condition and the tooth form of the saw blade. There-
fore, use only sharp saw blades that are suited for the material
to be worked.
Sawing Wood
The correct selection of the saw blade depends on the type
and quality of the wood and whether lengthway or crossway
cuts are required.
When cutting spruce lengthways, long spiral chips are
formed.
Beech and oak dusts are especially detrimental to health.
Therefore, work only with dust extraction.
Sawing Plastic (GKS 65 GCE)
Note: When sawing plastic, especially PVC, long spiral chips
are formed that can be electrostatically charged. This can clog
the sawdust ejector 15 and cause the retracting blade guard
12 to jam. It is best to work with dust extraction.
Guide the switched on power tool against the workpiece and
carefully start the cut. Continue the cut with low feed and
without interruption, so that the saw teeth do not gum up too
quickly.
Sawing Non-ferrous Metals (GKS 65 GCE)
Note: Use only a sharp saw blade that is suitable for non-fer-
rous metals. This ensures a clean cut and prevents blade bind-
ing.
Guide the switched on power tool against the workpiece and
carefully start the cut. Continue the cut with low feed and
without interruption.
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 65 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 30 (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 11 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 11
through the guide in the base plate 13. 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 clamped to the workpiece as an auxiliary guide; the
base plate of the circular saw can be guided alongside the aux-
iliary guide.
Sawing with Guide Rail (GKS 65 G/GKS 65 GCE)
(see figure F)
The guide rail 30 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 30 to the circular saw being used. For this, place
the guide rail 30 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 to one with use of the con-
nection piece 31. 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.
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 machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
