Sawdust Blower Device
With the air jet of the sawdust blower device 6,
the cutting line can be kept free of dust and
chips.
Switching on the sawdust blow-
er device: For cuts in materials
with high removal rate, such as
in wood, plastic, etc., push the
switch 6 toward the vacuum
connection.
Switching off the sawdust blow-
er device: For cuts in metal and
when a dust extraction system is
connected, push the switch 6 to-
ward the saw blade.
Starting Operation
Observe correct mains voltage! The voltage
of the power 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 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.
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.
Controling the Stroke Rate
Increasing or reducing the pressure on the
On/Off switch 2 enables stepless stroke-rate
control of the switched-on machine.
When the On/Off switch 2 is locked, it is not
possible to reduce the stroke rate.
The required stroke rate is dependent on the
material and the 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.
Bosch Power Tools
After longer periods of work at low stroke rate,
the machine can heat up considerably. Remove
the saw blade from the machine and allow the
machine to cool down by running it for approx.
3 minutes at maximum stroke rate.
Working Advice
Before any work on the machine itself, pull
the mains plug.
When working small or thin workpieces, al-
ways use a stable support or a saw station
(Bosch PLS 300).
Plunge Cutting (see figure F)
Plunge cuts may only be applied to soft ma-
terials, such as wood, gypsum plaster
boards, etc.!
Use only short saw blades for plunge cutting.
Plunge cutting is possible only with the mitre an-
gle set at 0°.
Place the machine with the front edge of the
base plate 5 on to the workpiece without the
saw blade 8 touching the workpiece and switch
on. For machines with stroke rate control, select
the maximum stroke rate. Firmly hold the ma-
chine against the workpiece and by tilting the
machine, slowly plunge the saw blade into the
workpiece.
When the base plate 5 fully lays on the work-
piece, continue sawing along the desired cutting
line.
Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cut-
ter 19 (accessory), the thickness of the material
must not exceed a maximum of 30 mm.
Remove the "Cut Control" base 10 from base
plate 5. For this, lightly press the base together
and remove it from the guide 15.
Parallel Cuts (see figure G): Loosen the locking
screw 20 and slide the scale of the parallel guide
through the lead 15 in the base plate. Set the
desired cutting width as the scale value on the
inside edge of the base plate. Tighten the lock-
ing screw 20.
