Vacuum Connection; Maintenance And Cleaning - Bosch GST 135 CE PROFESSIONAL Instructions D'emploi

Dust/Chip Extraction
■ The dust that is produced while working can be
detrimental to health, inflammable or explo-
sive. Suitable safety measures are required.
Examples: Some dusts are regarded as carci-
nogenic. Use suitable dust/chip extraction and
wear a dust respirator.
■ Dust from light alloys can burn or explode. Al-
ways keep the workplace clean, as blends of
materials are particularly dangerous.

Vacuum Connection

The vacuum connection 6 is used to connect a
vacuum hose.
When inserting the vacuum connection 6 in the
base plate 7, make sure that the plastic tip of the
vacuum connection engages in the correspond-
ing hole of the motor casing (see figure
To enable optimum dust extraction, use the splin-
ter guard 23.
The machine can be plugged directly into the re-
ceptacle of a Bosch all-purpose vacuum cleaner
with remote starting control. The vacuum cleaner
starts automatically when the machine is
switched on.
The vacuum cleaner must be suitable for the ma-
terial to be worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
For external dust extraction with a vacuum
cleaner, an extraction adapter must be used as
required (see accessories). Insert extraction
adapter and vacuum connection firmly.
Cover Guard
The transparent cover guard 17 enables the col-
lection of chips and sawdust. To achieve opti-
mum results, it must always be mounted when
working with dust extraction. When working with-
out dust extraction, do not use the dust cover 17.
Otherwise sawdust/wood chips can block the
view.
Tips
For tight curves it is best to use a narrow saw
blade.
When sawing metal or similar materials, apply
coolant/lubricant alongside the cutting line.

Straight Cuts in Thick Wood
– With the pushbutton for Precision Control 11,
switch on the lateral guidance feature of the
saw blade.
– Use Bosch saw blades labelled "Precision for
Wood".
– Adjust the exact cutting angle with use of a
commercial angle gauge 20.
– Operate the machine with low feed only; the
orbital action and the stroke ensure sufficient
operational progress.
– Always guide the machine firmly against the
parallel guide 24 or an auxiliary guide rail and
avoid lateral pressure against the handle in or-
der to prevent the machine from jamming.
Circle Cutter/Parallel Guide
(Accessory – see figures
F ).
With the combined circle cutter/parallel guide 24,
circular cutouts or parallel cuts in materials of up
to 30 mm thickness can be made.

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 order to avoid operational malfunctions, do
not saw gypsum board from below or over-
head.
In extreme working conditions, conduc-
tive 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 extraction system is recom-
mended in such cases as well as fre-
quently blowing out the ventilation slots
and installing a residual current de-
vice (RCD).
The guide roller 13 should occasionally be
checked for wear and lubricated with a drop of oil.
If it is worn, it must be replaced.
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.
