Declaration of Conformity
We declare under our sole responsibility that the product de-
scribed under “Technical Data” is in conformity with the fol-
lowing standards or standardization documents: EN 60745
according to the provisions of the directives 2004/108/EC,
2006/42/EC.

The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
Mounting/Replacing the Saw Blade
f Before any work on the machine itself, pull the mains
plug.
f When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
f
Only use saw blades that correspond with the charac-
teristic data given in the operating instructions.
f
Do not under any circumstances use grinding discs as
the cutting tool.
Selecting a Saw Blade
An overview of recommended saw blades can be found at the
end of this manual.
Removal of the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
– Press the spindle lock button
5 and keep it pressed.
f The spindle lock button 5 may be actuated only when
the saw spindle is at a standstill. Otherwise, the power
tool can be damaged.
– With the Allen key 19 , unscrew the clamping bolt 20 turn-
ing in rotation direction
n
.
– Tilt back the retracting blade guard 12 and hold firmly.
– Remove the clamping flange 21 and the saw blade 22 from
the saw spindle 24 .
Mounting the Saw Blade (see figure A)
For changing the cutting tool, it is best to place the machine
on the face side of the motor housing.
– Clean the saw blade
22 and all clamping parts to be assem-
bled.
– Tilt back the retracting blade guard 12 and hold firmly.
– Place the saw blade 22 on to the mounting flange 23 . The
cutting direction of the teeth (direction or arrow on saw
blade) and the direction-of-rotation arrow on the blade
guard 1 must correspond.
– Mount the clamping flange 21 and screw in the clamping
bolt 20 turning in rotation direction
o
. Observe correct
mounting position of mounting flange 23 and clamping
flange 21 .
– Press the spindle lock button 5 and keep it pressed.
– With the Allen key 19 , tighten the clamping bolt 20 turning
in rotation direction
o
. The tightening torque is between
10–12 Nm, which corresponds to hand tight plus ¼ turn.
Adjusting the Riving Knife (GKS 85 G)
(see figure B)
f
Before any work on the machine itself, pull the mains
plug.
f
Always work with the riving knife, except when carry-
ing out plunge cuts. The riving knife prevents jamming of
the saw blade while sawing.
Adjustment is carried out at minimal cutting depth, see “Ad-
justing the Cutting Depth”, page 18.
It is best to place the machine on the face side of the blade
guard 1 .
Loosen the clamping lever 28 , pull the saw away from the
base plate 14 and then tighten the clamping lever 28 again.
Loosen screw 25 , adjust the riving knife 13 to the measure
shown in the figure and tighten screw 25 with a tightening
torque between 8–9 Nm.
