Inserting the saw blade (see figure A)
Press the SDS lever (4) forward and guide the saw blade (1)
behind the clamping plate (7) into the saw blade
receptacle (3). Release the SDS lever (4).
Check that it is seated securely by pulling the saw
u
blade. A loose saw blade can fall out and lead to injuries.
For particular jobs, the saw blade (1) can also be flipped
180° (teeth point upwards) and refitted.
Removing the saw blade
Let the saw blade cool down before removing it. There
u
is a risk of injury when touching the hot saw blade.
Press the SDS lever (4) forward and pull out the saw
blade (1). Release the SDS lever (4).
Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
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-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Starting Operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Switching on/off
To switch on the power tool, press the on/off switch (5) and
keep it pressed.
To switch off the power tool, release the on/off switch (5).
Note: For safety reasons, the on/off switch (5) cannot be
locked; it must remain pressed during the entire operation.
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 (5) to varying
extents.
Bosch Power Tools
Applying light pressure to the on/off switch (5) 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.
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.
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.
Swivelling base plate (see figure B)
Thanks to its mobility, the base plate (2) adopts the required
angle position of the surface.
Plunge cutting (see figures C–D)
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.
