Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cut-
ter 25 (accessory), the thickness of the material
must not exceed a maximum of 30 mm.
Parallel Cuts (see figure J): Loosen the locking
screw 24 and slide the scale of the parallel guide
through the lead 23 in the base plate. Set the
desired cutting width as the scale value on the
inside edge of the base plate. Tighten the lock-
ing screw 24.
Circular Cuts (see figure K): Set the locking
screw 24 to the other side of the parallel guide.
Slide the scale of the parallel guide through the
lead 23 in the base plate. Drill a hole in the work-
piece centred in the section to be sawn. Insert
the centring tip 26 through the inside opening of
the parallel guide and into the drilled hole. Set
the radius as the scale value on the inside edge
of the base plate. Tighten the locking screw 24.
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
malfunctions. Therefore, do not saw materials
that produce a lot of dust from below or over-
head.
Bosch Power Tools
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The pro-
tective insulation of the machine can be de-
graded. The use of a stationary extraction
system is recommended in such cases as
well as frequently blowing out the ventila-
tion slots and installing a residual current
device (RCD).
Lubricate the guide roller 9 occasionally with a
drop of oil.
Check the guide roller 9 regularly. If worn, it
must be replaced through an authorised Bosch
after-sales service agent.
If the machine should fail despite the care taken
in manufacturing 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 include the 10-digit article
number given on the type plate of the machine.
