Working Advice

When working small or thin work pieces, al-
ways use a sturdy support or a saw table (ac-
cessory).
Contact Protector
The contact protector 3 attached to the casing
prevents accidental touching of the saw blade
during the working procedure and may not be re-
moved.
Plunge Cutting (see figure E)
Plunge cuts may only be applied to soft ma-
terials, such as wood, gypsum plaster
boards, etc.!
Use only short saw blades for plunge cutting.
Plunge cutting is possible only with the mitre an-
gle set at 0°.
Place the machine with the front edge of the
base plate 4 on to the workpiece without the saw
blade 1 touching the workpiece 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 4 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
19 (accessory), the thickness of the material
must not exceed a maximum of 30 mm.
Parallel Cuts (see figure F): Loosen the locking
screw 18 and slide the scale of the parallel guide
through the lead 17 in the base plate. Set the de-
sired cutting width as the scale value on the in-
side edge of the base plate. Tighten the locking
screw 18.
Circular Cuts (see figure G): Set the locking
screw 18 to the other side of the parallel guide.
Slide the scale of the parallel guide through the
Bosch Power Tools
lead 17 in the base plate. Drill a hole in the work-
piece centred in the section to be sawn. Insert
the centring tip 20 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 18.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be
applied alongside cutting line because of the ma-
terial 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, re-
move 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 overhead.
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 2 occasionally with a
drop of oil.
Check the guide roller 2 regularly. If worn, it must
be replaced through an authorised Bosch after-
sales service agent.
