Place the machine with the front edge of the base plate 7 on
to the workpiece without the saw blade 9 touching the work-
piece and switch on. For machines with stroke rate control,
select the maximum stroke rate. Firmly hold the machine
against the workpiece and by tilting the machine, slowly
plunge the saw blade into the workpiece.
When the base plate 7 fully lays on the workpiece, continue
sawing along the desired cutting line.
Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cutter 21 (acces-
sory), the thickness of the material must not exceed a maxi-
mum of 30 mm.
Parallel Cuts (see figure F): Loosen the locking screw 20 and
slide the scale of the parallel guide through the lead 19 in the
base plate. Set the desired cutting width as the scale value on
the inside edge of the base plate. Tighten the locking screw 20.
Circular Cuts (see figure G): Set the locking screw 20 to the
other side of the parallel guide. Slide the scale of the parallel
guide through the lead 19 in the base plate. Drill a hole in the
workpiece centred in the section to be sawn. Insert the centring
tip 22 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 20.
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 in-
stall a residual current device (RCD). When working met-
als, conductive dust can settle in the interior of the power
tool. The total insulation of the power tool can be impaired.
Lubricate the guide roller 8 occasionally with a drop of oil.
Check the guide roller 8 regularly. If worn, it must be replaced
through an authorised Bosch after-sales service agent.
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.
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.
