ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-

Operation

Starting Operation

Inserting the battery

Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Press the lock-off button (6) to the right to protect the
power tool from being switched on unintentionally.
Insert the charged battery (4) into the battery receptacle un-
til you feel it engage and it is securely locked in place.
Switching On and Off (see figure D)
To switch on the power tool, press the lock-off switch to the
left (6) first. Then press the on/off switch (7) and keep it
pressed.
The worklight lights up when the on/off switch (7) is lightly
or fully pressed allowing the work area to be illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (7).
Then press the lock-off button (6) to the right again.
Controlling 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 (7) to varying
extents.
Applying light pressure to the on/off switch (7) 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
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.
Temperature monitoring/overload protection indicator
The red temperature monitoring/overload protection indic-
ator (9) helps you to protect the battery against overheating
and the motor against overload.
If the temperature monitoring/overload protection indic-
ator (9) is lit up permanently in red, the temperature of the
battery is too high and the power tool switches off automat-
ically.
Bosch Power Tools
Switch the power tool off and allow the battery to cool down
before you carry on working.
If the temperature monitoring/overload protection indic-
ator (9) is flashing red, then the power tool is blocked and
will switch off automatically.
Pull the power tool out of the workpiece. The power tool will
continue to work at the set stroke rate as soon as the block-
age is rectified.

Working Advice

Remove the battery from the power tool before carry-
u
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.
Switch the power tool off immediately if the saw blade
u
becomes blocked.
Tips
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Before sawing into wood, chipboard, building materials,
etc., check for any foreign objects such as nails, screws, etc.
and use a suitable saw blade.
Switch on the power tool and guide it towards the workpiece
you wish to work on. Place the base plate (2) on the surface
of the workpiece and saw through the material applying even
pressure and feed. Switch the power tool off once you have
finished your work.
Switch the power tool off immediately if the saw blade jams.
Widen the sawing gap slightly with a suitable tool and pull
the power tool out.
Plunge cutting (see figure E)
Plunge cuts may only be applied to soft materials,
u
such as wood, gypsum board, etc. Do not plunge cut
metal materials.
For plunge cutting, use only short saw blades.
Place the power tool so that the edge of the base plate (2)
rests on the workpiece, without the saw blade (1) touching
the workpiece, and switch it on. When using 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 (2) rests fully on the workpiece,
continue sawing along the required cutting line.
For particular jobs, the saw blade (1) can also be fitted after
being turned 180° in order to operate the power tool the
other way around.
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.
