Operation
Operating Modes
Before any work on the machine itself, pull the mains
plug.
Adjusting the Cutting Depth (see figure C)
Adjust the cutting depth to the thickness of the work-
piece.
Less than a full tooth of the blade teeth should be
visible below the workpiece.
Loosen wing bolt
14
. For a smaller cutting depth, pull the saw
away from the base plate
13
; for a larger cutting depth, push
the saw toward the base plate
13
. Adjust the desired cutting
depth at the cutting-depth scale. Tighten wing bolt
14
again.
Adjusting the Cutting Angle
Loosen wing bolt
6
. Tilt the saw sidewards. Adjust the desired
setting at the scale
5
. Tighten wing bolt
6
again.
Note:
For bevel cuts, the cutting depth is smaller than the set-
ting indicated on the cutting-depth scale
15
.
Cutting Marks
The 0° cutting mark
9
indicates the position of the saw blade
for right-angled cuts. The 45° cutting mark
8
indicates the po-
sition of the saw blade for 45° cuts.
For precise cuts, position the circular saw against the work-
piece as shown in the figure. It is best to carry out a trial cut.
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er 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 save energy, only switch the power tool on when us-
ing it.
To
start
the machine,
first
push the lock-off button 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.
Working Advice
Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the cutting di-
rection. Excessive feed significantly 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. There-
fore, 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 extraction.
Sawing with Parallel Guide (see figure D)
The parallel guide
10
enables exact cuts along a workpiece
edge and cutting strips of the same dimension.
Loosen wing bolt
7
and slide the scale of the parallel guide
10
through the guide in the base plate
13
. Adjust the desired cut-
ting width as the scale setting at the respective cutting mark
9
or
8
; see Section “Cutting Marks”. Tighten wing bolt
7
again.
Sawing with Auxiliary Guide (see figure E)
For sawing large workpieces or straight edges, a board or
strip can be clamped to the workpiece as an auxiliary guide;
the base plate of the circular saw can be guided alongside the
auxiliary guide.
Sawing with Guide Rail (see figure G)
The guide rail
28
is used to carry out straight cuts.
The adhesive coating prevents the guide rail from slipping and
protects the surface of the workpiece. The coating of the
guide rail allows the circular saw to glide easily.
The rubber lip on the guide rail acts as a splinter guard; it pre-
vents fraying of the surface while sawing wooden materials.
For this, the teeth of the saw blade must face directly against
the rubber lip.
The guide rail 28 must not extend beyond the face side of
the workpiece where the cut is to be started.
The guide-rail adapter
27
is required for working with the
guide rail
28
. The guide-rail adapter
27
is mounted in the
same manner as the parallel guide
10
.
The following work steps are required for exact cuts using the
guide rail
28
:
– Place the guide rail
28
on to the workpiece projecting light-
ly over the side. Pay attention that the side with the rubber
lip faces to the workpiece.
