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 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.
Controlling 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.
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, always use a
stable support or a saw station (Bosch PLS 300).
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
as wood, gypsum plaster boards, etc.!
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.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains
plug.
For safe and proper working, always keep the machine
and ventilation slots clean.
Clean the saw blade holder regularly. For this, remove the saw
blade from the machine and lightly tap out the machine on a
level surface.
Heavy contamination of the machine can lead to malfunctions.
Therefore, do not saw materials that produce a lot of dust from
below or overhead.
In extreme conditions, always use dust extraction as far
as possible. Blow out ventilation slots frequently and in-
stall a residual current device (RCD). When working met-
als, conductive dust can settle in the interior of the power
tool. The total insulation of the power tool can be impaired.
Lubricate the guide roller 14 occasionally with a drop of oil.
Check the guide roller 14 regularly. If worn, it must be re-
placed through an authorised Bosch after-sales service agent.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
