Dust Extraction - Bosch GDA 280 E Manual Del Usuario

Dust extraction

Dust extraction prevents large ac-
cumulations of dust, high concen-
trations of dust in the ambient air
and facilitates disposal.
For long periods of working with
wood or for commercial use on ma-
terials that produce dust that is det-
rimental to health, the machine is
to be connected to a suitable exter-
nal dust extraction device.
The machine has a built-in vacuuming channel
which, in conjunction with a suitable vacuum
cleaner, provides external dust extraction.
For extraction, a 19 mm dia. vacuum hose 1 can
be connected directly to the vacuum connec-
tion 2. When using a 35-mm dia. vacuum hose,
an additional adapter
(1 600 499 005 - see accessories).
The appliance can be plugged directly into the
socket of a Bosch all-purpose vacuum cleaner
which incorporates a remote-control start device.
The vacuum cleaner automatically starts when
the appliance is switched on.
Operating instructions
The material removal during sanding is deter-
mined primarily by the selection of the sanding
sheet and the setting of the oscillation rate.
For exact sanding in corners, on edges and
hard-to-reach places, sanding can be done with
the point alone or with one of the edges of the
sanding sheet.
Only flawless sanding sheets produce good
sanding results and protect the machine.
Take care to apply uniform sanding pressure;
the service life of the sanding sheet is in-
creased in this manner.
An increase in the sanding pressure does not
increase the sanding performance but causes
increased wear to the machine and the sand-
ing tools.
Do not sand wood and metal with the same
sanding sheet.
Use only original Bosch sanding sheets,
polishing tools and accessories.
