Initial Operation
Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
For starting operation of the machine, actuate
the lock-off button 2 first, and then press and hold
the On/Off switch 3 afterwards.
To switch off the machine, release the On/Off
switch 3.
For safety reasons the On /Off switch of
the machine cannot be locked; it must
remain pressed during the entire opera-
tion.
Speed Preselection (GKS 66 CE)
With the adjustment knob 5, the speed can be
continuously selected. The required speed is de-
pendent on the saw blade used and the material
to be worked (see Saw Blade Table).
Constant Electronic Control
(GKS 66 CE)
The constant electronics ensures that the ma-
chine speed is the same regardless of the load
conditions; this ensures uniform work advancing
and a smooth cutting pattern.
Temperature Dependent Overload
Protection (GKS 66 CE)
When the machine is overloaded while sawing,
the motor stops and starts again only when the
advancing rate is reduced. For machines that
have become warm during operation, the temper-
ature dependent overload protection will react
earlier. The reaction time will be dependent on
the initial temperature of the machine.
Reduced Starting Current (GKS 66 CE)
Due to the gradual, smooth starting procedure of
the machine, a 13 A fuse is sufficient.

Changing the Tool
Before any work on the machine itself, pull
the mains plug.
Wear protective gloves.
The saw blades used must correspond to
the characteristic data in these operating
instructions.
Use only saw blades with an allowable
speed matching at least the no-load speed
of the machine.
Removing (see figure
Press spindle lock 1 and keep depressed.
The spindle lock 1 may be actuated only
when the saw blade is at a standstill.
Unscrew clamping bolt 18 with the Allen key 17.
Remove clamping flange 19.
Tilt back the retracting blade guard 13 and hold
firmly.
Remove the saw blade.
Mounting (see figure
Clean the saw blade and all the clamping parts to
be assembled.
Tilt back the retracting blade guard 13 and hold
firmly.
Place the saw blade onto the mounting flange 20.
Assemble the clamping bolt 18 with the washer
and assemble the clamping flange 19.
Tighten the clamping bolt 18 with the Allen
key 17. Tightening torque: 6 – 9 Nm; equivalent to
1
hand-tight plus /

Take care that the mounting positions of
the mounting flange 20 and clamping
flange 19 are correct.
When mounting: Ensure that the cutting di-
rection of the teeth (direction of arrow on
saw blade) and the direction-of-rotation ar-
row on the blade guard match.
