Dust/Chip Extraction; Starting Operation - Bosch GSA 10,8 V-LI Professional Manual Original

Inserting the Saw Blade (see figure B)
– Press the saw blade 1 firmly into the saw
blade holder 12 until it can clearly be heard to
engage. This causes the locking sleeve 3 to
turn by approx. 90° and locks the saw blade.
If the saw blade 1 is not locked, turn the lock-
ing sleeve 3 approx. 90° in the direction of the
arrow until it locks in the open position and a
"click" can be heard. Then press the saw
blade 1 into the saw blade holder 12 again.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to inju-
ries.
For certain work, the saw blade 1 can also be
turned through 180° (with the teeth pointed up-
wards) and re-inserted again.
Ejecting the Saw Blade (see figure C)
When ejecting the saw blade, hold the ma-
chine in such a manner that no persons or
animals can be injured by the ejected saw
blade.
– Turn the locking sleeve 3 approx. 90° in the
direction of the arrow. The saw blade 1 is
ejected.

Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions 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.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Prevent dust accumulation at the work-
place. Dusts can easily ignite.

Operation

Starting Operation

Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
– Push the lock-off button 6 leftward to pro-
tect the power tool against accidental
switching on.
– Insert the charged battery 11 into the handle
until it can be felt to engage and faces flush
against the handle.
Starting and Stopping (see figure D)
– Push the lock-off button 6 rightward.
– To start the machine, press the On/Off
switch 7 and keep it pressed.
– To switch off the machine, release the
On/Off switch 7.
– Afterwards, push the lock-off button 6 left-
ward again.
Controling the Stroke Rate
Increasing or reducing the pressure on the
On/Off switch 7 enables stepless stroke-rate
control of the switched-on machine.
The required stroke rate is dependent on the
material and the working conditions and can be
determined by a practical trial.
Reducing the stroke rate is recommended when
the saw blade engages in the material as well as
when sawing plastic and aluminium.
