Operation

Operating Modes

Before any work on the machine itself, pull
the mains plug.
Adjusting the Cutting Angle (see figures B
and C)
The base plate 5 can be swivelled by 45° to the
left or right for mitre cuts.
Insert a saw blade 8.
Loosen the screw 12 and lightly slide the base
plate 5 toward the vacuum connection 4.
For adjustment of precise mitre angles, the base
plate has adjustment notches on the left and
right at 0°, 22.5° and 45°. Swivel the base plate
5 to the desired position according to the scale
13. Other mitre angles can be adjusted using a
protractor.
Afterwards, push the base plate 5 to the stop in
the direction of the saw blade 8.
Position the holder for the guide roller 11 in
such a manner that the guide roller 7 faces
against the back of the saw blade. Precise cuts
are possible only when the guide roller faces
tightly against the back of the saw blade.
Tighten the screw 12 again.
Offsetting the Base Plate (see figure B)
For sawing close to edges, the base plate 5 can
be offset to the rear.
Insert a saw blade 8.
Loosen the screw 12 and slide the base plate 5
toward the vacuum connection 4 to the stop.
Bosch Power Tools

such a manner that the guide roller 7 faces
against the back of the saw blade. Precise cuts
are possible only when the guide roller faces
tightly against the back of the saw blade.
Tighten the screw 12 again.
Sawing with the base plate 5 offset is possible
only with a mitre angle of 0°.
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 blower device: For
cuts in materials with high removal rate, such
as in wood, plastic, etc., push the switch 6 to
position "I".
Switching off the sawdust blower device: For
cuts in metal and when a dust extraction system
is connected, push the switch 6 to position "0".

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.

Working Advice

When working small or thin work pieces,
always use a sturdy support or a saw table
(accessory).
Coolant/Lubricant
When sawing metal, coolant/lubricant should
be applied alongside cutting line because of the
material heating up.
