Circular Cuts (see figure K): Drill a hole (large enough to acco-
modate the saw blade) close to the cutting line within the cir-
cle to be sawn. Work the drill hole with a router or file to en-
sure that the saw blade faces flush against the cutting line.
Reposition the locking screw 27 on the other side of the par-
allel guide. Slide the scale of the parallel guide throught the
lead 23 in the base plate. Drill a hole in the centre of the cut-
out to be sawn. Insert the centring tip 28 through the inside
opening of the parallel guide and into the drilled hole. Adjust
the radius as scale value at the inside edge of the base plate.
Tighten the locking screw 27.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.

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.
Clean the saw blade holder regularly. For this, remove the saw
blade from the machine and lightly tap out the machine on a
level surface.
Heavy contamination of the machine can lead to malfunc-
tions. Therefore, do not saw materials that produce a lot of
dust from below or overhead.
In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When work-
ing metals, conductive dust can settle in the interior of the
power tool. The total insulation of the power tool can be im-
paired.
Lubricate the guide roller 18 occasionally with a drop of oil.
Check the guide roller 18 regularly. If worn, it must be re-
placed through an authorised Bosch after-sales service agent.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
