When sawing profiles, always begin the cut from
the narrow side; when sawing U-profiles, never
start the cut from the open side. Support long
profiles in order to avoid blade binding and kick-
back of the power tool.
Sawing with Parallel Guide (see figure D)
The parallel guide 11 enables exact cuts along a
workpiece 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 F–H)
The guide rail 29 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.
For sawing at a right angle, the circular saw can
be placed directly onto the guide rail 29. Fasten
the guide rail 29 with suitable clamping devices,
e. g., screw clamps, on the workpiece in such a
manner that the narrow leg of the guide rail 29
faces toward the saw blade.
The guide rail 29 must not extend beyond the
face side of the workpiece where the cut is to
be started.
The guide-rail adapter 32 is required for bevel
cuts with the guide rail 29. The guide-rail adapt-
er 32 is mounted in the same manner as the par-
allel guide 11.
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 direct-
ly against the rubber lip.

The following work steps are required for exact
cuts using the guide rail 29:
– Place the guide rail 29 on to the workpiece
projecting 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 32 on to the guide rail 29.
– Adjust the desired cutting depth and the bev-
el angle. Observe the marks on the guide-rail
adapter 32 for preadjustment of the various
bevel angles; see figure F.
– Align the circular saw with guide-rail adapter
in such a manner that the teeth of the saw
blade 21 face against the rubber lip. The po-
sition of the saw blade 21 depends on the se-
lected 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 premount-
ed guide-rail adapter 32 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.
