Dust/Chip Extraction; Starting Operation - Bosch PSR 18 LI-2 Ergonomic Notice Originale

16 | English
The drill spindle is locked when the On/Off switch 5 is not
pressed. This makes quick, convenient and easy changing of
the tool in the drill chuck possible.
Open the keyless chuck 1 by turning in rotation direction ,
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 1 by hand in ro-
tation direction  until the locking action ("click") is no longer
heard. This automatically locks the chuck.
The locking is released again to remove the tool when the col-
lar is turned in the opposite direction.

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 car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
Operation

Starting Operation

Inserting the battery
 Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Set the rotational direction switch 6 to the centre position to
protect the power tool against accidental starting.
Slide the charged battery 9 from behind into the foot of the
power tool. Press the battery fully into the foot until the bat-
tery is securely locked.
Reversing the rotational direction (see figure B)
The rotational direction switch 6 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 5 actuated.
Right rotation: To drill and to drive in screws, press the rota-
tional direction switch 6 forward through to the stop.
Left rotation: To loosen or unscrew screws, press the rota-
tional direction switch 6 backward through to the stop.
Setting the torque
The torque presetting ring 2 can be used to pre-select the re-
quired torque in 20 stages. When the correct setting is used,
the bit will be stopped as soon as the screw is driven flush into
the material or as soon as the set torque has been reached. In
position " " the overload clutch is deactivated, e. g. for
1 609 92A 1MX | (17.10.17)
drilling or driving in very large screws.
When unscrewing screws, perhaps select a higher setting or
set the tool to the " " symbol.
Setting the operating mode (PSB 18 LI-2 Ergonomic)
(see figure C)
The operating mode preselection ring 3 can be used to
choose between screwdriving, drilling and impact drilling.
In the "Impact drilling" position, the safety clutch is deactivat-
ed and the maximum power is always effective.
Gear selection, mechanical
 The gear selector 4 can be actuated at standstill or
when the machine is running. However, this should not
be done while operating at full load or maximum speed.
Two speed ranges can be preselected with the gear selector 4.
Gear I:
Low speed range; for screwdriving or working with large drill-
ing diameter.
Gear II:
High speed range; for working with small drilling diameter.
If the gear selector 4 cannot be pushed through to the stop,
lightly turn the drill chuck with drill bit.
Switching On and Off
To start the machine, press the On/Off switch 5 and keep it
pressed.
To switch off the machine, release the On/Off switch 5.
To save energy, only switch the power tool on when using it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch 5
is pressed.
Light pressure on the On/Off switch 5 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Rapid Shut-off
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unexpect-
ed rotation of the power tool around the drilling axis.
The rapid shut-off feature is indicated by a flashing LED on the
power tool.
 Rapid shut-off can trigger only when the power tool is
running at maximum operating speed and can rotate
freely around the drill bit axis. Choose a suitable work
position for this. Otherwise, rapid shut-off will not be en-
sured.
To restart the machine, release the On/Off switch and then
actuate again.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 5 is not pressed, the drill spindle and
thus the tool holder are locked.
This enables screws to be screwed in, even when the battery is
empty and allows for the machine to be used as a screwdriver.
