Dust/Chip Extraction; Operating Modes; Starting Operation - Bosch GSA 18V-32 Professional Manual Original

16 | English
While replacing the saw blade, ensure that the saw
u
blade receptacle is free of material residue, e.g. wood
or metal chips.
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 a 1/2" universal shank. The saw blade should not be
longer than required for the intended cut.
Inserting the saw blade (see figure B)
Swing the lever for saw blade release (3) approx. 60° in the
direction of the arrow and hold it in place. Push the saw
blade (1) into the saw blade receptacle (14). Release the
lever for saw blade release again.
Check that it is seated securely by pulling the saw
u
blade. A loose saw blade can fall out and lead to injuries.
For particular jobs, the saw blade (1) can also be flipped
180° (teeth point upwards) and refitted.
Removing the saw blade (see figure B)
Let the saw blade cool down before removing it. There
u
is a risk of injury when touching the hot saw blade.
Swing the lever for saw blade release (3) approx. 60° in the
direction of the arrow and hold it in place. Remove the saw
blade (1). Release the lever for saw blade release again.

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-
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

Operating modes

Pendulum action settings
The pendulum action can be adjusted using three 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 pendulum action rotary switch (5).
Level 0 (pendulum action switched off):
– For processing thin or hard materials, e.g. sheet metal,
steel
1 609 92A 4TL | (09.07.2019)
– For producing clean cutting edges
Level 1:
– For processing non-ferrous metals, hardwood, plastics or
materials of medium strength
Level 2:
– For processing non-ferrous metals, hardwood, plastics or
materials of medium strength
– For processing soft materials, e.g. lightweight materials,
insulation materials, softwood, other wood

Starting Operation

Inserting the battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Slide the charged battery (9) from behind into the foot of
the power tool. Press the battery fully into the base until the
battery is securely locked.
Switching on/off
To switch on the power tool, press the lock-off button (8)
forwards first. Then press the on/off switch (7) and keep it
pressed.
The worklight lights up when the on/off switch (7) is lightly
or fully pressed allowing the work area to be illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (7).
Note: For safety reasons, the on/off switch (7) cannot be
locked; it must remain pressed during the entire operation.
Controlling/preselecting the stroke rate
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (7) to varying
extents.
Applying light pressure to the on/off switch (7) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
You can also preselect the stroke rate and change it during
operation using the stroke rate preselection thumbwheel
(6).
1: Low stroke rate
6: High stroke rate
The required stroke rate is dependent on the material and
the work conditions and can be determined using practical
tests.
It is recommended that you reduce the stroke rate when
placing the saw blade on the workpiece and when sawing
plastic and aluminium.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.
Constant Electronic control
The Constant Electronic control keeps the stroke rate at no
load and under load virtually consistent, guaranteeing uni-
form performance.
