The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when
placing the saw blade on the workpiece and when sawing
plastic and aluminium.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.
Controlling the stroke rate (GST18V‑LIB)
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (2) to varying
extents.
Applying light pressure to the on/off switch (2) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when

During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.
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
temperature is reached or the load is reduced. If it automat-
ically shuts down, switch the power tool off, allow the bat-
tery to cool down, then switch the power tool back on.
Working Advice
u Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
u Switch the power tool off immediately if the saw blade
becomes blocked.
u Always use a sturdy support when working on small or
thin workpieces.
Before sawing into wood, chipboard, building materials,
etc., check for and remove any foreign objects such as nails,
screws, etc.
Plunge cutting (see figureH)
u Plunge cuts may only be applied to soft materials,
such as wood, gypsum board, etc.
For plunge cutting, use only short saw blades. Plunge cutting
is possible only with a mitre angle of 0°.
Place the power tool so that the front edge of the base plate
(7) rests on the workpiece, without the saw blade (10)
touching the workpiece, and switch it on. On power tools
with stroke rate control, select the maximum stroke rate.
Press the power tool firmly against the workpiece and allow
the saw blade to plunge slowly into the workpiece.
As soon as the base plate (7) rests fully on the workpiece,
continue sawing along the required cutting line.
Coolant/lubricant
As the material heats up along the cutting line when cutting
metal, you should apply coolant or lubricant.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50°C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Maintenance and Service
Maintenance and Cleaning
u Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
u To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
Clean the saw blade receptacle regularly. For this, remove
the saw blade from the power tool and lightly tap out the
power tool on a level surface.
If the power tool becomes very dirty, this can lead to serious
faults. For this reason, do not cut materials which generate
large quantities of dust from below or overhead.
If the dust outlet becomes blocked, switch off the power
tool, disconnect the dust extraction system and remove the
dust and chips.
Apply a drop of oil to the guide roller (9) from time to time.
Check the guide roller(9) regularly. If worn, it must be re-
placed through an authorised Bosch after-sales service
centre.
