Infinitely-variable stroke rate
adjustment
(GST 100 BCE)
Light application of pressure on on/off switch 2
results in low stroke rate. Increasing pressure re-
sults in a higher stroke rate.
Stroke Rate Selection/
Constant Electronics with Soft Start
(GST 100 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
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
"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 maxi-
mum stroke rate and no load for approx. 3 min-
utes.
Contact Protector
The contact protector 5 attached to the machine
prevents unintentional contact with the saw blade
while working.
Dust Vacuuming with the
External Extractor Device
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 com-
mercial use on materials that produce dust that is
detrimental to health, the machine is to be con-
nected to a suitable external dust extraction de-
vice.

Vacuuming Connector Piece
The vacuuming connector piece 15 serves for the
connecting of a suitable vacuum hose.
When inserting the connection piece 15 into the
base plate 12, take care that the plastic nose of
the vacuuming adapter engages in the corre-
sponding hole on the motor housing (see Figure).
For vacuuming, a Bosch 19 mm dia. vacuum
with
hose 16 can be directly connected to the connec-
tor piece 15. 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 4 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
Removal: Take hold of the cover at the sides,
the contact protector 5 and snap on.
tilt slightly and pull off to the front.
