Operating modes
Setting the Cutting Depth (see figure C)
Adapt the cutting depth to the thickness of the work-
u
piece. A space of less than the height of one full tooth
should be visible under the workpiece.
Loosen the clamping lever (26). For a smaller cutting depth,
pull the saw away from the base plate (13); for a larger cut-
ting depth, push the saw towards the base plate (13). Adjust
the desired cutting depth at the cutting-depth scale.
Retighten the clamping lever (26).
If you are unable to fully adjust the cutting depth after
loosening the clamping lever (26), pull the clamping lever
(26) away from the saw and swivel it downwards. Loosen
the clamping lever (26) again. Repeat this process until the
required cutting depth can be set.
If you are unable to adequately fix the cutting depth after
tightening the clamping lever (26), pull the clamping lever
(26) away from the saw and swivel it upwards. Loosen the
clamping lever (26) again. Repeat this process until the cut-
ting depth is fixed.
Adjusting the mitre/bevel angle
We recommend that you place the power tool down on the
front side of the protective guard (16).
Loosen the clamping lever (8) and wing bolt (28). Swivel the
saw to the side. Set the required mitre/bevel angle on the
scale (6). Retighten the clamping lever (8) and wing bolt
(28).
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (27).
Cut marks
The 0° cut mark (9) indicates the position of the saw blade
when making a right-angled cut. The 45° cut mark (10) indic-
ates the position of the saw blade when making a 45° cut –
when used without a guide rail.
Start-up
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
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.
Bosch Power Tools
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
Pull the plug out of the socket before carrying out any
u
work on the power tool.
The width of cut varies depending on the saw blade used.
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.
