7.3 Setting direction of rotation, transporting
safety device (switch-on lock)
7.4 Selecting gear stage
Do not set the switch (3) unless the motor has
stopped completely!
7.5 Setting torque limitation,
drilling, impact drilling
7.6 Switching on/off, setting speed
Fig. A
Switching on, speed: press the trigger (13). The
speed can be changed by pressing in the
trigger.
Switching off: release the trigger (13). 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 period of operation.
Notes on machines with the designation SB...:
1. The ratchet sound which can possibly be heard
after opening the drill chuck is functional and is
switched off by a reverse rotation of the sleeve.
2. Clamping tool:
Turn sleeve in direction "GRIP, ZU" until the
noticeable mechanical resistance has been
overcome.
Caution! The chuck is not yet fully tight-
ened! Keep turning the sleeve (it must "click"
when turning)) until it cannot be turned any
further - only now is the tool safely clamped.
Cleaning: From time to time, hold the machine
vertically with the keyless chuck facing
downwards and turn the sleeve fully in direction
"GRIP, ZU" and then turn fully in direction
"AUF, RELEASE". The dust collected falls from
the keyless chuck.
7.8 Unscrewing chuck
Employ the same procedure when attaching the
chuck, except in reverse order.
7.9 Chuck with quick bit change system (for
BS 14.4 LT Quick, BS 18 LT Quick)
Fig. I
To remove: Push the interlock ring forward (a),
advance and pull off the chuck (b).
To mount: Push the interlock ring forward and
move the chuck as far as the limit stop on the drill
spindle.

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 (contin-
uous beeping). The beeping stops after a maximum
of 30 seconds or when the trigger (13) 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 is flashing (10), the battery pack is
almost flat. If necessary, press the (9) button
and check the LEDs (10) 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 was
SWITCHED OFF automatically. If the slew rate
of the current is too high (for example, if the
machine suddenly seizes or kickback occurs),
the machine switches off. Switch off the machine
at the trigger (13). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing.
Switch off the machine at the trigger (13). Then
continue working as normal. Try to prevent the
machine from seizing.
