Working Advice

 Before any work on the machine itself, pull the mains
plug.
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 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 H)
The parallel guide 10 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 10
through the guide in the base plate 12. Adjust the desired cut-
ting width as the scale setting at the respective cutting mark
30 or 29; see Section "Cutting Marks". Tighten wing bolt 8
again.
Sawing with Guide Rail (see figures I–K)
The guide rail 31 is used to carry out straight cuts.
The adhesive coating prevents the guide rail from slipping and
protects the surface of the workpiece.
The guide rail 31 can be extended. For this, turn around both
guide rails 31 by 180° and connect both guide rails 31 by in-
serting them. Press button 32 to lock the guide rails. To disas-
semble the guide rails, press the opposite button 32 and pull
the guide rails 31 apart.
The guide rail 31 has two marks on the top side. The side with
the "90°" mark is used for right-angled cuts, and the side with
the "45°" mark is used for all other mitre cuts.
The rubber lip on the guide rail acts as a splinter guard for 90°
and 45° cuts; it prevents fraying of the surface while sawing
wooden materials.
Bosch Power Tools
Upon initial sawing, the rubber lip is adapted to your circular
saw, and slightly cut off in this process.
Note: On the workpiece side where the cut is being started,
the guide rail 31 must always face flush against the work-
piece, and may not project beyond it.
Should the guide rail 31 project beyond the workpiece end,
do not rest the circular saw on the guide rail 31 without hold-
ing the circular saw. The guide rail 31 is made of plastic and
cannot hold the circular saw.
Fasten the guide rail 31 to the workpiece using the special
screw clamps 33. Take care that the cam on the inside of the
screw clamp 33 is seated in the corresponding recess of the
guide rail 31.
Switch the machine on and guide it in the cutting direction ap-
plying moderate and steady feed.

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.
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.
