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 (15) 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 Fig. A, B (The
electronics protect the battery pack against
damage through total discharge).
If one LED is flashing (11), the battery pack is
almost flat. If necessary, press the (10) button
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 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 (15). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing.
Switch off the machine at the trigger (15). Then
continue working as normal. Try to prevent the
machine from seizing.
8.2 Note:
The LED lamp (14) switches off automatically after
a specific time.
To activate the electronic functions: press the
trigger (15).
Use only genuine Metabo accessories.
Use only accessories that fulfil the requirements
and specifications listed in these operating instruc-
tions.
Fit accessories securely. Secure the machine if it is
operated in a bracket. Loss of control can cause
personal injury.

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 short-
circuiting (e. g. by protecting them with adhesive
tape).
