Dust/Chip Extraction
u Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can
cause allergic reactions and/or lead to respiratory
infections of the user or bystanders. Certain dusts,
such as oak or beech dust, are considered as
carcinogenic, especially in connection with wood-
treatment additives (chromate, wood preservative).
Materials containing asbestos may only be worked by
specialists.
– As far as possible, use a dust extraction system
suitable for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filterclass respirator.
Observe the relevant regulations in your country for the
materials to be worked.
u Prevent dust accumulation at the workplace. Dusts
can easily ignite.
Integrated Dust Extraction with Dust Box (see figures D1 – D4)
(GSS 140 - 1A)
Mount the dust box 2 onto the extraction outlet 9.
The filling level of the dust box 2 can easily be checked
through the transparent container.
To empty the dust box 2, pull it off toward the rear with a
slight twisting motion.
Screw the filter element 10 off the dust box 2. Empty the dust
box.
To loosen the dust, gently strike or tap the filter element 10
against a firm surface. Clean the lamellas of the filter element
10 with a soft brush.
Note: To ensure optimum dust extraction, empty the dust
box 2 in good time and clean the filter element 10 at regular
intervals.
When working vertical surfaces, hold the power tool in such
a manner that the dust box 2 faces downward.
External Dust Extraction (see figure E) (GSS 140 - 1A)
Mount the vacuum hose 11 (accessory) onto the extraction
outlet 9. Connect the vacuum hose 11 with a vacuum cleaner
(accessory).
The vacuum cleaner must be suitable for the material being
worked. Be found at the end of these operating instructions.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
When working vertical surfaces, hold the power tool in such a
manner that the vacuum hose faces downward.

Operation

Starting Operation

Switching On and Off
To start the machine, tilt the On/Off switch 1 toward the
right to the "I" position.
To switch off the machine, tilt the On/Off switch 1 toward
the left to the "0" position.
Working Advice
u Wait until the machine has come to a standstill
before placing it down.
The removal capacity during sanding is mainly determined by
the selection of the sanding sheet.
Only flawless sanding sheets achieve good sanding capacity
and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this increases
the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an increase
of the sanding capacity, but to increased wear of the machine
and the sanding sheet.
A sanding sheet that has been used for metal should not be
used for other materials.
Use only original Bosch sanding accessories.

Maintenance and cleaning

u Before any work on the machine itself, pull the mains
plug.
u For safe and proper working, always keep the machine
and ventilation slots clean.
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
include the 10-digit article number given on the type plate
of the machine.
