Splintering Protector
The splintering protector 17 prevents the splinter-
ing of the surface when sawing in wooden mate-
rials.
Press the splintering protector from below into the
base plate 12.
The splintering protector cannot be
used for certain saw blade types (e.g.,
saw blades with set).
Glide Shoe for Base Plate
The aluminium base plate 12 with a steel inlay
provides the highest possible stability and is in-
tended for the working of metal or insensitive sur-
faces without the use of the glide shoe 13.
For the working of sensitive materials, the glide
show 13 prevents the scratching of the surface.
To attach the glide show, hook it onto the base
plate at the front, press it up at the back and latch.
Application Tips
Plunge Sawing
Only soft materials such as wood, aer-
ated concrete, plaster board, etc. may
be worked with the plunge method.
Cut-outs in wood are possible without predrilling
by piercing with the running machine. This re-
quires a certain amount of practice, however, and
is possible only with short saw blades.
Place the front edge of the base plate on the
workpiece and switch on. Press the machine
firmly against the workpiece and plunge the saw
blade slowly into the workpiece (Fig. F).
After reaching the required cutting depth, bring
the machine again to the normal working position
so that the complete surface of the base plate
rests on the workpiece and continue to saw along
the cutting line (Fig. G).
After completing the cut, switch off the machine
first and then pull it out of the cut.

Circle cutter/Parallel guide
(Accessory)
With the combined
guide 19 you can make circular cut-outs or paral-
lel cuts in materials of up to 30 mm thickness (see
Fig. D/E).
For tight-radius curves it is best to use a narrow
saw blade. You can find the appropriate types in
the table on the back flap.
Apply coolant or lubricant to deal with the heat
produced along the cut line when sawing metal.
Maintenance and Cleaning
Before all work on the machine, pull the
plug from the socket!
For safe and proper working, always keep the
machine and the ventilation slots clean.
To prevent malfunctions from excessive soil-
ing, materials that produce large amounts of
dust such as plaster board should not be
worked from below or overhead.
To ensure the long-term flawless operation of
the machine, the SDS saw blade holder should
be cleaned regularly. This can be done, for ex-
ample, by lightly tapping the machine with its
foot plate against a flat surface.
In extreme operating conditions (e. g.
when working with non-ferrous metals)
the interior of the machine can become
blocked with cuttings.
In such cases it is recommended to use a sta-
tionary extractor, reduce the cleaning cycles
and connect an earth-leakage circuit-breaker.
Guide roller 8 should occasionally be checked for
wear and lubricated with a drop of oil. If, after a
long period, it should display extensive wear, it
must be replaced by a professional or at an au-
thorised Bosch Service Station for electric tools.
If the machine should happen to fail despite the
care taken in manufacture and testing, repair
should be carried out by an authorised customer
services agent for Bosch power tools.
For all correspondence and spare parts orders,
always include the 10 digit order number of the
machine!
