Cutting Marks
45 0
The 0° cutting mark (10) indicates the position
of the saw blade for right-angled cuts. The 45°
cutting mark (9) indicates the position of the
saw blade for 45° cuts.
For precise cuts, position the circular saw
against the workpiece as shown in the figure. It
is best to carry out a trial cut.

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, first push the lock-off but-
ton for the On/Off switch 2 and then press the
On/Off switch 1 and keep it pressed.
To switch off the machine, 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.
Reduced starting current (GKS 65 CE)
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Constant Electronic Control (GKS 65 CE)
Constant electronic control holds the speed
constant at no-load and under load, and ensures
uniform working performance.
Bosch Power Tools
Temperature Dependent Overload Protection
(GKS 65 CE)
In case of overload, the machine switches off
until the optimal operating-temperature range is
reached again. Release the On/Off switch 1 and
45 0
switch the machine on again to continue work-
ing.
Speed preselection (GKS 65 CE)
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 direction. Excessive feed significant-
ly 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. Therefore, 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 extrac-
tion.
Sawing Plastic (GKS 65 CE)
Note: When sawing plastic, especially PVC, long
spiral chips are formed that can be electrostati-
cally 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.
