Declaration of Conformity
On our own responsibility, we hereby declare that these battery-powered drilling screwdrivers and impact drills, identified by type and serial number 1), meet all relevant requirements of directives 2) and standards 3). Technical documents at 4) – Fig. M.
Specified Use
The drills and impact drills are suitable for drilling in metal, wood,
plastic, and similar materials, and also for screw driving and thread tapping.
The impact drills are also suited for drilling in masonry, brickwork, and
stone.
The user bears sole responsibility for any damage caused by improper use.
Generally accepted accident prevention regulations and the enclosed safety
information must be observed.
General safety instructions
For your own protection and for the protection of your power tool, pay
attention to all parts of the text that are marked with this symbol!
WARNING – Reading the operating instructions will reduce the risk of
injury.
WARNING Read all safety warnings and instructions. Failure to follow all
safety warnings and instructions may result in electric shock, fire, and/or
serious injury.
Keep all safety instructions and information for future reference.
Pass on your electrical tool only together with these documents.
Special Safety Instructions
Wear ear protectors with impact drills (machines with the designation
SB). Exposure to noise can cause hearing loss.
Hold the tool by insulated gripping surfaces, when performing an operation
where the cutting accessory may contact hidden wiring. If the cutting
accessory contacts a “live” wire, exposed metal parts of the electrical tool
may become “live” and give the operator an electric shock.
Ensure that the spot where you wish to work is free of power cables, gas lines
or water pipes (e.g. by using a metal detector).
Protect battery packs from water and moisture!
Do not expose battery packs to naked flame!
Do not use faulty or deformed battery packs!
Do not open battery packs!
Do not touch or short-circuit battery packs!
Slightly acidic, flammable fluid may leak from defective li-ion battery packs!
If battery fluid leaks out and comes into contact with your skin, rinse
immediately with plenty of water. If battery fluid leaks out and comes into
contact with your eyes, wash them with clean water and seek medical attention
immediately.
If the machine is defective, remove the battery pack from the machine.
Remove the battery pack from the machine before any adjustments, conversions,
or servicing are performed.
Before fitting the battery pack, make sure that the machine is switched off.
Keep hands away from the rotating tool!
Remove chips and similar material only with the machine at a standstill.
Secure the workpiece to prevent slipping or rotation (e.g. by securing it with
screw clamps).
LED lights (11): Do not observe the LED radiation directly with optical
instruments.
Transport of li-ion battery packs:
The shipping of li-ion battery packs is subject to laws related to the
carriage of hazardous goods (UN 3480 and UN 3481). Inform yourself of the
currently valid specifications when shipping li-ion battery packs. If
necessary, consult your freight forwarder.
Certified packaging is available from Metabo.
Only send the battery pack if the housing is intact and no fluid is leaking.
Remove the battery pack from the machine for sending. Prevent the contacts
from short-circuiting (e.g. by protecting them with adhesive tape).

Use
7.1 Battery pack, capacity, and signal display Fig. B
Charge the battery pack before use.
If performance diminishes, recharge the battery pack.
The ideal storage temperature is between 10°C and 30°C.
7.2 Removing, and replacing battery pack Fig. C
7.3 Setting direction of rotation, transporting safety device (switch-on lock)
Fig. D
7.4 Selecting gear stage Fig. E
Do not set the switch (3) unless the motor has stopped completely!
7.5 Setting torque limitation, drilling, impact drilling Fig. F
7.6 Switching on/off, setting speed Fig. A
Switching on, speed: press the trigger (12). The speed can be changed by
pressing in the trigger.
Switching off: release the trigger (12).
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 Fig. G
With a soft tool shank, retightening may be required after a short period of
operation.
Notes on machines with the designation SB…:
- 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.
- Clamping tool:
Turn the sleeve in the direction “GRIP, ZU” until the noticeable mechanical resistance has been overcome.
Caution! The chuck is not yet fully tightened! 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 the direction “GRIP, ZU” and then turn fully in the direction “AUF, RELEASE”. The dust collected falls from the keyless chuck.
7.8 Unscrewing chuck Fig. H
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.
7.10 Attaching the belt hook (depending on machine features)/bit depot
(depending on machine features) Fig. J
Attach the belt hook to the left (6), as shown.
Attach the bit depot to the right (5), as shown.
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 (12) 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:
-
Battery pack almost empty Fig. A, B (The electronics protect the battery pack against damage through total discharge).
If one LED is flashing (9), the battery pack is almost flat. If necessary, press the (8) button and check the LEDs (9) to see the charge level.
If the battery pack is almost flat, it must be recharged. -
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. -
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 (12). Switch it on again and continue to work as normal. Try to prevent the machine from seizing.
Switch off the machine at the trigger (12). Then continue working as normal. Try to prevent the machine from seizing.

Environmental Protection
Do not allow battery packs to come into contact with water!
To protect the environment, do not dispose of power tools or battery packs in
household waste. Observe national regulations on separated collection and
recycling of disused
machines, packaging, and accessories.
Before disposal, discharge the battery pack in the power tool. Prevent the
contacts from shortcircuiting (e. g. by protecting them with adhesive tape).

Emission values
Using these values, you can estimate the emissions from this power tool and
compare these with the values emitted by other power tools. The actual values
may be higher or lower, depending on the particular application and the
condition of the tool or power tool. In estimating the values, you should also
include work breaks and periods of low use. Based on the estimated emission
values, specify protective measures for the user – for example, any
organisational steps that must be put in place.
