Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching on/off
To start the power tool, first press the lock-off switch (2),
then press and hold the on/off switch (1).
To switch off the power tool, release the on/off switch (1).
Note: For safety reasons, the on/off switch (1) cannot be
locked; it must remain pressed during the entire operation.
Starting current limitation (GKS 65 GCE)
The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.
Constant Electronic (GKS 65 GCE)
The Constant Electronic keeps the speed at no load and un-
der load virtually consistent, guaranteeing uniform perform-
ance.
Temperature Dependent Overload Protection (GKS 65
GCE)
In the event of overload, the power tool switches off until it
returns to the optimum operating temperature range. Re-
lease the on/off switch (1) and switch the power tool back
on to continue working.
Speed preselection (GKS 65 GCE)
You can preselect the required speed using the thumbwheel
for speed preselection (3), even during operation.
The required speed depends on the saw blade used and the
material being worked on (see the saw blade overview at the
end of these operating instructions). This will prevent the
saw teeth overheating when sawing.
Practical advice
Protect saw blades against shock and impact.
Guide the power tool evenly, pushing it gently in the cutting
direction. Applying too much pressure to the power tool
when moving it in the cutting direction significantly reduces
the service life of the application tools and can damage the
power tool.
The sawing performance and the quality of the cut essen-
tially depend on the condition and the tooth shape of the
saw blade. This is why you should only use sharp saw blades
that are suitable for the material being machined.
Sawing wood
Choosing the right saw blade depends on the wood type,
wood quality and whether cuts with or against the grain are
required.
Making cuts in spruce with the grain produces long, spiral-
shaped chips.
Beech and oak dust is especially detrimental to health.
Therefore, work only with dust extraction.

Sawing lightweight materials (materials containing
minerals) (GKS 65 GCE)
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Lightweight materials may only be worked on using dry cuts
and with a dust extraction system. Always use the guide rail
(30) (accessory).
The dust extractor must be approved for extracting stone
dust. Suitable dust extractors are available from Bosch.
Sawing with a parallel guide (see figure D)
The parallel guide (11) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Loosen the wing bolt (7) and slide the scale of the parallel
guide (11) through the guide in the base plate (13). Adjust
the desired cutting width as a scale value at the correspond-
ing (9) or (10) cut mark, see the section "Cut marks".
Retighten the wing bolt (7).
Sawing with an auxiliary guide (see figure E)
For working on large workpieces or for cutting straight
edges, you can securely fasten a board or rail to the work-
piece as an auxiliary guide. The circular saw can be guided
along the path of this auxiliary guide with the base plate.
Sawing with a guide rail (GKS 65 G/GKS 65 GCE) (see
figure F)
You can use the guide rail (30) to produce straight cuts.
The rubber lip on the guide rail acts as an anti-splinter guard,
which prevents the surface from splintering when sawing
wooden materials. To fulfil this function, the saw blade must
be positioned with its teeth right up against the rubber lip.
Before making the first cut with the guide rail (30), the rub-
ber lip must be adapted to the circular saw used. To do so,
position the guide rail (30) along the entire length of a work-
piece. Set a cutting depth of approx. 9 mm and a right-
angled mitre/bevel angle. Switch on the circular saw and
guide it evenly, pushing it gently in the cutting direction.
The connector (31) can be used to join two guide rails. The
four screws in the connector are used for the purpose of
clamping.
Maintenance and Servicing
Maintenance and Cleaning
Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
The retracting blade guard must always be able to move
freely and retract automatically. It is therefore important to
