7.4
Selecting the gear
Do not set the switch (4) unless the motor has
stopped completely!
7.5
Setting the torque limitation,
screwdriving, drilling and impact drilling
Fig. F
= Set screwdriving by turning the sleeve
(3)
AND
set the torque (with torque limitation) by
turning the sleeve (2) - intermediate
settings are also possible.
= Set drilling by turning the sleeve (3) (max.
torque, without torque limitation)
To avoid overloading the motor, do not
jam the spindle.
Machines with the designation SB...:
= Set impact drilling by turning the sleeve
(3) (max. torque, without torque limitation)
To avoid overloading the motor, do not
jam the spindle.
7.6
Switching On/Off, setting the speed
Fig. A
Switching on, speed: press the trigger switch (14).
Press in the trigger switch to increase the
rotational speed.
Switching off: release the trigger switch (14). Note:
the noise that the machine makes when it
switches off is due to the design (quick stop)
and has no influence on the function or the
service life of the machine.
7.7
Keyless chuck
With a soft tool shank, retightening may be required
after a short drilling period.
Information for machines with the designation
BS 18 LT BL, SB 18 LT BL:
1. The grating sound which may be heard after
opening the chuck is functional and is stopped
by turning the sleeve in the opposite direction.
2. Clamping the tool:
Turn sleeve in direction "GRIP, ZU" until the
noticeable mechanical resistance has been
overcome.
Caution! The tool is not yet clamped! Keep
turning the sleeve (it must "click" when
turning), until it cannot be turned any further -
only now is the tool securely clamped.
Cleaning: from time to time, hold the machine
vertically with the chuck facing downwards and
turn the sleeve fully in the direction "GRIP, ZU"
and then turn fully in the direction
"AUF, RELEASE". The dust collected falls from
the keyless chuck.
7.8
Unscrewing the chuck
Employ the same procedure when attaching the
chuck, except in reverse order.

Chuck with quick change system (with
BS 18 LT BL Q)
To remove: push the interlock ring forward (a),
advance and pull off the chuck forwards (b).
To fit: push the interlock ring forward and move the
chuck as far as the limit stop on the drill spindle.
7.10 Fitting the belt hook (equipment-
specific) / bit depot (equipment-specific)

Fit the belt hook (8) as shown.
Fit the bit depot (7) as shown.
8. Troubleshooting
8.1
The machine's multifunctional
monitoring system
If the machine switches off automatically, the
machine electronics have activated automatic
protection mode. A warning signal sounds
(continuous beeping). The beeping stops after a
maximum of 30 seconds or when the trigger switch
(14) is released.
In spite of this protective function, overloading
is still possible with certain applications and
can result in damage to the machine.
Causes and remedies:
1. Battery pack almost empty
electronics protect the battery pack against
damage through total discharge).
If one LED (11) is flashing, the battery pack is
almost flat. If necessary, press the button (10)
and check the LEDs (11) to see the charge level.
If the battery pack is almost flat, it must be
recharged.
2. Long continuous overloading of the machine will
activate the temperature cut-out.
Leave the machine or battery pack to cool.
Note: if the battery pack feels very warm, the
pack will cool more quickly in an "AIR COOLED"
charger.
Note: the machine will cool more quickly if you
operate it at idling speed.
3. Metabo safety shutdown: the machine has
SHUT DOWN by itself. If the speed suddenly
drops (for example, if the machine suddenly
seizes or kickback occurs), the machine
switches off. Switch off the machine at the
trigger switch (14). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing.
9. Accessories
Use only original Metabo or CAS (Cordless Alliance
System) battery packs and accessories.
Use only accessories that fulfil the requirements
and specifications listed in these operating
instructions.
