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.

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, re-
move 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 over-
head.
Bosch Power Tools
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The pro-
tective insulation of the machine can be de-
graded. The use of a stationary extraction
system is recommended in such cases as
well as frequently blowing out the ventila-
tion slots and installing a residual current
device (RCD).
Lubricate the guide roller 7 occasionally with a
drop of oil.
Check the guide roller 7 regularly. If worn, it must
be replaced through an authorised Bosch after-
sales service agent.
WARNING! Important instructions for connect-
ing a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this power tool, it
must be disposed of safely.
If the machine should fail despite the care taken
in manufacturing 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 include the 10-digit article number
given on the type plate of the machine.
