Cut Control for Bevel Cuts
21 11 10 6
For cutting-line control of bevel cuts, the "Cut Control" view-
ing window 11 has a mark 21 for 0° right-angle cuts and a
mark 22 each for the left- or rightward sloping 45° bevel cut
according to scale 20.
The cutting mark for bevel cuts between 0° and 45° results
proportionally. It can additionally be drawn on the "Cut Con-
trol" viewing window 11 with a non-permanent marker, and
easily be removed again.
For accurate working, it is best to carry out a test cut.
Offsetting the Base Plate (see figure G)
For sawing close to edges, the base plate 6 can be offset to
the rear.
Loosen the screw 19 and slide the base plate 6 toward the
vacuum connection 4 to the stop.
Tighten the screw 19 again.
Sawing with the base plate 6 offset is possible only at a 0°
bevel angle. Additionally, "Cut Control" may not be used to-
gether with the base 10 as well as the splinter guard 16.
Sawdust Blower Device
With the air jet of the sawdust blower device 8, the cutting line
can be kept free of dust and chips.
Switching on the sawdust blower device:
For cuts in materials with high removal
rate, such as in wood, plastic, etc., push
the switch 8 toward the vacuum connec-
tion.
Switching off the sawdust blower device:
For cuts in metal and when a dust extrac-
tion system is connected, push the switch
8 toward the saw blade.

Starting Operation

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To save energy, only switch the power tool on when using it.
To start the machine, press the On/Off switch 2.
To lock the On/Off switch 2, keep it depressed and push the
lock-on button 1 to the right or left.
2 609 007 296 | (13.6.13)
To switch off the machine, release the On/Off switch 2. When
the On/Off switch 2 is locked, press it first and then release it.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 2
enables stepless stroke-rate control of the switched-on ma-
chine.
When the On/Off switch 2 is locked, it is not possible to re-
duce the stroke rate.
The required stroke rate is dependent on the material and the
22 20
working conditions and can be determined by a practical trial.
Reducing the stroke rate is recommended when the saw
blade engages in the material as well as when sawing plastic
and aluminium.
After longer periods of work at low stroke rate, the machine
can heat up considerably. Remove the saw blade from the ma-
chine and allow the machine to cool down by running it for ap-
prox. 3 minutes at maximum stroke rate.

Working Advice

 Before any work on the machine itself, pull the mains
 When working small or thin workpieces, always use a
Saw with moderate pressure in order to achieve optimal and
precise cutting results.
For long and straight cuts in thick wood (>40 mm), the cut-
ting line can become inaccurate. In this case, using a Bosch
circular saw is recommended to achieve accurate cuts.
Plunge Cutting (see figure H)
 Plunge cuts may only be applied to soft materials, such
Use only short saw blades for plunge cutting. Plunge cutting is
possible only with the mitre angle set at 0°.
Place the machine with the front edge of the base plate 6 on
to the workpiece without the saw blade 15 touching the work-
piece and switch on. For machines with stroke rate control,
select the maximum stroke rate. Firmly hold the machine
against the workpiece and by tilting the machine, slowly
plunge the saw blade into the workpiece.
When the base plate 6 fully lays on the workpiece, continue
sawing along the desired cutting line.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.
