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.
