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.
Plunge cutting (see figure J)
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
(6) rests on the workpiece, without the saw blade (11)
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 (6) 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.
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 (10) from time to time.
Check the guide roller (10) regularly. If worn, it must be re-
placed through an authorised Bosch after-sales service
centre.
Regularly spray the saw blade receptacle (15) with penetrat-
ing oil (see figure I).
