To switch off the power tool, release the on/off switch (3).
If the on/off switch (3) is locked, press the switch first and
then release it.
Controlling/preselecting the stroke rate
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (3) to varying
extents.
Applying light pressure to the on/off switch (3) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
It is not possible to reduce the stroke rate while the on/off
switch (3) is locked.
You can preselect the stroke rate and change it during opera-
tion using the stroke rate preselection thumbwheel (2).
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.

Working Advice

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Switch the power tool off immediately if the saw blade
u
becomes blocked.
When machining small or thin workpieces, always use
u
a stable base or saw table (accessory).
Before sawing into wood, chipboard, building materials,
etc., check for and remove any foreign objects such as nails,
screws, etc.
Jigsaws are primarily designed for curved cuts. The range of
products from Bosch also includes accessories which enable
straight cuts or circular cuts (depending on the jigsaw
model, e.g. parallel guide, guide rail or circle cutter).
Hand-held jigsaws generally tend to go off at an angle, i.e.
under certain circumstances the angle and cutting accuracy
can no longer be ensured. Decisive influencing factors on the
accuracy are the saw blade thickness, cutting length and the
material thickness and strength of the workpiece.
Therefore, always check using test cuts whether the cutting
result of the selected system meets the requirements of your
application.
Plunge cutting (see figure E)
Plunge cuts may only be applied to soft materials,
u
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
(5) rests on the workpiece, without the saw blade (8) touch-
ing the workpiece, and switch it on. On power tools with
Bosch Power Tools
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 (5) 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.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by an
after-sales service centre that is authorised to repair Bosch
power tools.
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.
In extreme conditions, always use a dust extractor if
u
possible. Blow out ventilation slots frequently and in-
stall a residual current device (RCD) upstream. When
machining metals, conductive dust can settle inside the
power tool, which can affect its protective insulation.
Apply a drop of oil to the guide roller (7) from time to time.
Check the guide roller (7) regularly. If worn, it must be re-
placed through an authorised Bosch after-sales service
centre.
