18 | English
After longer periods of work at low stroke rate, the machine
can heat up considerably. Remove the saw blade from the
machine and allow the machine to cool down by running it for
approx. 3 minutes at maximum stroke rate.
GST 18 V-LI B: Increasing or reducing the pressure on the
On/Off switch 2 enables stepless stroke-rate control of the
switched-on machine.
Light pressure on the On/Off switch 2 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
GST 18 V-LI S: With the thumbwheel for stroke rate preselec-
tion 16, the stroke rate can be preset and changed during
operation.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced or
the power tool switches off. At reduced speed, the power tool
will run again at full speed once the permitted battery temper-
ature is reached or the load is reduced. During automatic
shut-down, switch off the power tool, allow the battery to cool
down, then switch the power tool back on.
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 10 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.
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
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.
