Operating Instructions
Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the
cutting direction. Excessive feed significantly reduces
the service life of the saw blade and can cause dam-
age 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 length-
way 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
11
enables exact cuts along a work-
piece edge and cutting strips of the same dimension.
Loosen wing bolt
8
and slide the scale of the parallel
guide
11
through the guide in the base plate
14
.
Adjust the desired cutting width as the scale setting
at the respective cutting mark
10
or
9
; see Section
“Cutting Marks”. Tighten wing bolt
8
again.
Sawing with Auxiliary Guide (see figure E)
For sawing large workpieces or straight edges, a
board or strip can 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 figures G–H)
The guide rail
29
is used to carry out straight cuts.
The adhesive coating prevents the guide rail from slip-
ping 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
that prevents fraying or tearing out of the surface
when sawing wooden materials. For this, the teeth of
the saw blade must face directly against the rubber
lip.
The guide-rail adapter
28
is required for working with
the guide rail
29
. The guide-rail adapter
28
is mounted
in the same manner as the parallel guide
11
.
The following work steps are required for exact cuts
using the guide rail
29
:
•
Place the guide rail
29
on to the workpiece pro-
jecting lightly over the side. Pay attention that the
side with the rubber lip faces to the workpiece.
•
Set the circular saw with the premounted guide-
rail adapter
28
on to the guide rail
29
.
•
Adjust the desired cutting depth and the bevel
angle. Observe the marks on the guide-rail adapter
28
for preadjustment of the various bevel angles;
see figure G.
•
Align the circular saw with guide-rail adapter in
such a manner that the teeth of the saw blade
20
face against the rubber lip. The position of the saw
blade
20
depends on the selected cutting angle.
Do not saw into the guide rail.
•
Tighten wing bolt
8
to lock the position of the
guide-rail adapter.
•
Remove the circular saw with the premounted
guide-rail adapter
28
from the guide rail
29
.
•
Align the guide rail
29
on the workpiece in such a
manner that the rubber lip lies exactly alongside
the cutting edge.
•
The guide rail 29 must not extend beyond the
face side of the workpiece where the cut is to
be started.
•
Fasten the guide rail
29
with suitable clamping
devices, e. g., screw clamps, on the workpiece.
Set the circular saw with the premounted guide-
rail adapter
28
on to the guide rail.
•
Switch the machine on and guide it in the cutting
direction applying moderate and steady feed.
Two guide rails can be connected to one with use of
the connection piece
30
. Clamping is carried out with
the four screws located in the connection piece.
