Sawing Non-ferrous Metals
Note: Use only a sharp saw blade that is suitable for non-fer-
rous metals. This ensures a clean cut and prevents blade bind-
ing.
Guide the switched on power tool against the workpiece and
carefully start the cut. Continue the cut with low feed and
without interruption.
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 bind-
ing and kickback 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 7 and slide the scale of the parallel guide
11 through the guide in the base plate 14. Adjust the de-
sired cutting width as the scale setting at the respective
cutting mark 10 or 9; 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 (GKS 55+ G/GKS 55+ GCE)
(see figure F)
The guide rail 30 is used to carry out straight cuts.
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.
Prior to the very first cut, the rubber lip must be adapted with
the guide rail 30 to the circular saw being used. For this, place
the guide rail 30 over its complete length on a workpiece. Ad-
just a cutting depth of approx. 9 mm and the saw blade to a ze-
ro degree angle. Switch the circular saw on and guide it uni-
formly and with light feed in the cutting direction.
Two guide rails can be connected using the connection piece
32. Clamping is carried out with the four screws located in the
connection piece.
Maintenance and Service
Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean. Remove dust and
chips by blowing out with compressed air or with a brush.
Saw blades that are not coated can be protected against cor-
rosion with a thin coat of acid-free oil. Before use, the oil must
be removed again, otherwise the wood will become soiled.
1 609 92A 0LU | (1.8.14)
Resin and glue residue on the saw blade produces poor cuts.
Therefore, clean the saw blade immediately after use.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
