The sawing performance and the quality of the cut essen-
tially depend on the condition and the tooth shape of the
saw blade. This is why you should only use sharp saw blades
that are suitable for the material being machined.
Sawing wood
Choosing the right saw blade depends on the wood type,
wood quality and whether cuts with or against the grain are
required.
Making cuts in spruce with the grain produces long, spiral-
shaped chips.
Beech and oak dust is especially detrimental to health.
Therefore, work only with dust extraction.
Sawing non-ferrous metal
Note: Only use a sharp saw blade that is suitable for non-fer-
rous metal. This guarantees a clean cut and will prevent the
saw blade from jamming.
Switch on the power tool and bring it into contact with the
workpiece, sawing it carefully. Then continue working with
less feed and without interruption.
For profiles, always begin the cut on the narrow side; for U-
shaped profiles, never begin the cut on the open side. Sup-
port long profiles to prevent the saw blade jamming and the
power tool kicking back.
Sawing with a parallel guide (see figure D)
The parallel guide (10) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Loosen the wing bolt (8) and slide the scale of the parallel
guide (10) through the guide in the base plate (13). Adjust
the desired cutting width as a scale value at the correspond-
ing (25) or (24) cut mark, see the section "Cut marks".
Retighten the wing bolt (8).
Sawing with an auxiliary guide (see figure E)
For working on large workpieces or for cutting straight
edges, you can securely fasten a board or rail to the work-
piece as an auxiliary guide. The circular saw can be guided
along the path of this auxiliary guide with the base plate.
Maintenance and Service
Maintenance and Cleaning
Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
The retracting blade guard must always be able to move
freely and retract automatically. It is therefore important to
keep the area around the retracting blade guard clean at all
times. Remove dust and chips with a paintbrush.
Bosch Power Tools
Non-coated saw blades can be protected against corrosion
using a thin layer of acid-free oil. Remove the oil again before
sawing as failure to do so will stain the wood.
Resin or glue residue on the saw blade has a detrimental ef-
fect on the quality of the cut. You should therefore clean saw
blades straight after use.
