Contact Protector
The contact protector 3 attached to the machine
prevents unintentional contact with the saw blade
while working.
Infinitely-variable stroke rate adjust-
ment
(GST 100 BCE)
Light application of pressure on ON-OFF
switch 10 results in low stroke rate. Increasing
pressure results in a higher stroke rate.
Stroke Rate Selection
(GST 100 CE/BCE)
With the thumbwheel 1, the required stroke rate
can be selected (also while running).
1 - 2 = Low stroke rate
3 - 4 = Medium stroke rate
1
5 - 6 = High stroke rate
Constant Electronics with Soft Start
(GST 100 CE/BCE)
The built-in soft start electronics prevent a jerking
"Run-up" when the machine is switched on.
After the brief soft run-up, the machine is regu-
lated to the preselected stroke rate.
The Constant Electronics with
"Tach-generator" keeps the prese-
lected stroke rate nearly constant
also under load.
The stroke rate required depends upon the mate-
rial and the working conditions. The optimal set-
ting can be determined in practice. You can find
relevant information in the following table. After
working for longer periods at low stroke rate allow
the machine to cool by running it at maximum
stroke rate and no load for approx. 3 minutes.
Dust Vacuuming with the
External Extractor Device
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 re-
garded as carcinogenic. Use
suitable dust/chip extraction and
wear a dust mask.
Vacuuming Connector
14 • 2 609 932 100 • 09.01
Piece
The vacuuming connector piece 13 serves for the
connecting of a suitable vacuum hose.
When inserting the connection piece 13 into the
base plate 11, take care that the plastic nose of
the vacuuming adapter engages in the corre-
sponding hole on the motor housing (see
Figure ).
B
For vacuuming, a Bosch 19 mm dia. vacuum
hose 14 can be directly connected to the connec-
tor piece 13. The use of a 35 mm dia. vacuum
hose requires that an additional adapter be use
(1 600 499 005 - see accessories).
The machine can be connected directly to the
socket of a Bosch all-purpose vacuum cleaner
with a remote starting device. The vacuum
cleaner is started automatically when the ma-
chine is switched on.
So that optimum vacuuming of the sawdust is en-
sured, the vacuum channels and the vacuuming
adapter should be cleaned regularly.
Dust Cover
The transparent dust cover 2 makes possible the
collecting of the sawdust and must always be
mounted when dust vacuuming is used.
Mounting: Place the cover from the front onto
the contact protector 3 and snap on.
Removal: Take hold of the cover at the sides,
tilt slightly and pull off to the front.
Sawdust Blower
The sawdust blowing device directs a stream of
air at the saw blade. This prevents the cut line
from being covered by sawdust while working.
The air stream can be adjusted to one of three
levels with adjustment lever 9:
English - 3
Blower effect switched on:
For working with wood, plastic and
similar materials that produce large
amounts of sawdust.
Blower effect switched off:
For working with metals and when
cooling or lubricating agents are
used.
