Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch
2
enables stepless stroke-rate control of the switched-on ma-
chine.
Light pressure on the On/Off switch
2
results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
The required stroke rate is dependent on the material and the
working conditions and can be determined by a practical trial.
Reducing the stroke rate is recommended when the saw
blade engages in the material as well as when sawing plastic
and aluminium.
After longer periods of work at low stroke rate, the machine
can heat up considerably. Remove the saw blade from the ma-
chine and allow the machine to cool down by running it for ap-
prox. 3 minutes at maximum stroke rate.
Temperature Dependent Overload Protection
When using the machine as intended for, it cannot be subject to
overload. In case of excessive load or when not within the per-
mitted battery temperature range of 0–70 °C, the speed is re-
duced or the machine switches off. With reduced speed, the
machine will not run at full speed again until after reaching the
permitted battery temperature or when the load is reduced. In
case of automatic shut-off, switch the machine off, allow the
battery to cool down and then switch the machine on again.
Protection Against Deep Discharging
The Lithium-Ion battery is protected against deep discharging
by the “Electronic Cell Protection (ECP)”. When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Working Advice
When sawing small or thin workpieces, always use a
firm support.
Contact Protector
The contact protector
13
attached to the casing prevents ac-
cidental touching of the saw blade during the working proce-
dure and may not be removed.
Plunge Cutting (see figure I)
Plunge cuts may only be applied to soft materials, such
as wood, gypsum plaster boards, etc.!
Use only short saw blades for plunge cutting. Plunge cutting is
possible only with the mitre angle set at 0°.
Place the machine with the front edge of the base plate
7
on
to the workpiece without the saw blade
11
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)
Parallel Cuts (see figure J): Loosen the locking screw
24
and
slide the scale of the parallel guide through the lead
10
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
24
.
Circular Cuts (see figure K): Set the locking screw
24
to the oth-
er side of the parallel guide. Slide the scale of the parallel guide
through the lead
10
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 (e.g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
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.
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.
The plastic guide plate
6
should be replaced when worn.
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.
