Bosch GST 8000 E Original Instructions Manual page 13

Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Inserting/changing the saw blade
When fitting or changing the saw blade, wear protect-
u
ive gloves. Blades are sharp and can become hot when
used for prolonged periods of time.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
with single lug shank (T shank). The saw blade should not be
longer than required for the intended cut.
Use a narrow saw blade when sawing tight curves.
Inserting the saw blade (see figure A)
Clean the shaft on the saw blade before inserting it.
u
A dirty shaft cannot be securely fixed in place.
Push the saw blade (8), with the teeth in the cutting direc-
tion, into the saw blade receptacle (11) until it clicks into
place. The SDS lever (12) automatically springs back and
the saw blade is locked in place. Do not push the lever (12)
back by hand as you could damage the power tool.
Make sure when inserting the saw blade that the back of the
saw blade is in the groove on the guide roller (7).
Check that the saw blade is seated securely. A loose
u
saw blade can fall out and lead to injuries.
Ejecting the saw blade (see figure B)
When ejecting the saw blade, hold the power tool in
u
such a manner that no persons or animals can be in-
jured by the ejected saw blade.
Turn the SDS lever (12) as far as it will go in the direction of
the shock protection guard (9). The saw blade is released
and ejected.
Anti-splinter guard (see figure C)
The anti-splinter guard (13) (accessory) can prevent splin-
tering of the surface while sawing wood. The anti-splinter
guard can only be used with certain saw blade types and only
at a cutting angle of 0°. When sawing with the anti-splinter
guard, the base plate (5) must not be moved to the rear for
sawing close to edges.
Push the anti-splinter guard (13) into the base plate (5)
from below (as shown in the figure with the groove facing up-
wards).
Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
Bosch Power Tools
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Operating modes
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Pendulum action settings
The pendulum action can be adjusted using four different
settings, allowing the cutting speed, cutting capacity and the
cut itself to be optimally adapted to the material that you
want to cut.
You can also adjust the pendulum action during operation
using the adjusting lever (6).
Level 0 No pendulum action
Level I Low pendulum action
Level II Moderate pendulum action
Level III High pendulum action
The optimum pendulum level for each application can be de-
termined by a practical test. Note the following recommend-
ations:
– Select a lower pendulum level or switch off the pendulum
action completely if you wish to produce a finer or cleaner
cutting edge.
– Switch off the pendulum action when machining thin ma-
terials (e.g. sheets).
– Work on hard materials (e.g. steel) with low pendulum ac-
tion.
– You can work on soft materials and saw wood in the direc-
tion of the grain using maximum pendulum action.
Adjusting the mitre/bevel angle (see figure D)
The base plate (5) can be swivelled to the right or left to
make mitre cuts up to 45°.
The anti-splinter guard (13) cannot be used while mitre cuts
are being made.
– Remove the anti-splinter guard (13).
– Loosen the screw (15) and push the base plate (5)
slightly towards the mains cable.
– The base plate has lock-in points at 0° and 45° on the left
and right so that precise mitre/bevel angles can be set.
Swivel the base plate (5) to the desired position accord-
ing to the scale (14). Other mitre/bevel angles can be ad-
justed using a protractor.
