scale value on the inside edge of the base plate. Retighten
the locking screw (24).
Circular cuts (see figure H): Drill a hole large enough to push
the saw blade through on the cutting line within the circle to
be cut. Machine the drill hole with a router or file so that the
saw blade can lie flush with the cutting line.
Position the locking screw (24) on the other side of the par-
allel guide. Slide the scale on the parallel guide through the
guide (23) into the base plate. Drill a hole in the workpiece
in the middle of the section to be cut out. Insert the centring
tip (26) through the inner opening of the parallel guide and
into the drilled hole. Adjust the radius as a scale value on the
inside edge of the base plate. Retighten the locking screw
(24).
Coolant/lubricant
As the material heats up along the cutting line when cutting
metal, you should apply coolant or lubricant.
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.
Clean the saw blade receptacle regularly. For this, remove
the saw blade from the power tool and lightly tap out the
power tool on a level surface.
If the power tool becomes very dirty, this can lead to serious
faults. For this reason, do not cut materials which generate
large quantities of dust from below or overhead.
In extreme conditions, always use a dust extractor if
u
possible. Blow out ventilation slots frequently and in-
stall a residual current device (RCD) upstream. When
machining metals, conductive dust can settle inside the
power tool, which can affect its protective insulation.
If the dust outlet becomes blocked, switch off the power
tool, disconnect the dust extraction system and remove the
dust and chips.
Apply a drop of oil to the guide roller (9) from time to time.
Check the guide roller (9) regularly. If worn, it must be re-
placed through an authorised Bosch after-sales service
centre.
