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.
7.9
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.

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
(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 (10) is flashing, the battery pack is
almost flat. If necessary, press the button (9) 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 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 (13). 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.

For a complete range of accessories, see
www.metabo.com or the catalogue.
10. Repairs
Repairs to electrical tools must ONLY be
carried out by qualified electricians!
Contact your local Metabo representative if you
have Metabo power tools requiring repairs. See
www.metabo.com for addresses.
You can download a list of spare parts from
www.metabo.com.
11. Environmental Protection
Do not allow battery packs to come into contact with
water!
Protect the environment, and do not dispose
of power tools and battery packs with house-
hold waste. Observe national regulations on
separated collection and recycling of disused
machines, packaging and accessories.
Discharge the battery pack in the power tool before
disposal. Prevent the contacts from short-circuiting
(e.g. by protecting them with adhesive tape).
