Maintenance And Cleaning - Bosch PWS 700 Bedienungsanleitung

Cutting
When cutting, do not press, jam or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being machined.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.
When cutting profiles and square pipes, it is best
to start with the smallest cross section.
Cutting Stone
The machine must be used only for dry
cutting/grinding.
It is best to use a diamond cutting disc. As a
safety measure against jamming, use the cutting
guide 17 with the special dust extraction protec-
tion guard.
Operate the machine with dust extraction only. In
addition, wear a dust mask.
Slide the machine with moderate feed, adapted
to the material to be worked (Figure).

The direction in
which the cutting is
performed is impor-
tant.
The machine must
always work in an
up-grinding motion.
Therefore, never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed uncon-
trolled out of the cut.
The vacuum cleaner
must be approved for
the extraction of ma-
sonry dust.
Bosch provides suit-
able vacuum clean-
ers.
Switch on the ma-
chine and place the
front part of the cut-
ting guide on the
workpiece.

For cutting especially hard material, e. g., con-
crete with high pebble content, the diamond cut-
ting disc can overheat and become damaged as
a result. This is clearly indicated by circular
sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
freely at no-load speed for a short time.
Noticeable decreasing work progress and circu-
lar sparking are indications of a diamond cutting
disc that has become dull. Briefly cutting into
abrasive material (e. g., lime-sand brick) can re-
sharpen the disc.

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and the ventilation slots clean.
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The
protective insulation of the machine can be
degraded. The use of a stationary extrac-
tion system is recommended in such cases
as well as frequently blowing out the venti-
lation slots and installing a residual current
device (RCD).
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 orders,
please always include the 10-digit order number
given on the nameplate of the machine.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
strain relief
live = brown
neutral = blue
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 machine, it must
be disposed of safely.
