7. Cleaning, Maintenance
The power tool should be cleaned regularly, often
and thoroughly through all air vents using a vacuum
cleaner or by blowing in dry air. Prior to this
operation, separate the power tool from the power
source and wear protective glasses and dust mask.
8. Troubleshooting
Elektronic signal indicator (12)
Flashing - restart protection
When power is restored after a power failure,
the machine - which is still switched on - will
not start for safety reasons. Switch machine on and
off again.
Continuously illuminated - overload
If the machine is overloaded for a long period
of time, the power intake is limited to avoid
further excessive heating of the motor.
Allow the machine to run at idle speed until it has
cooled off and the electronic signal indicator goes
out.
9. Accessories
Use only genuine Metabo accessories.
Use only accessories that fulfil the requirements
and specifications listed in these operating
instructions.
See page 4.
A Extensive drill bit and chisel assortment for a
wide range of applications.
B Special grease (for lubricating the tool shanks)
C Dust extraction system
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!
The connection cable must only be replaced by
Metabo or an authorised customer service
workshop.
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
Observe national regulations on environmentally
compatible disposal and on the recycling of disused
machines, packaging and accessories.

Emission values
These values make it possible to assess the
emissions from the power tool and to compare
different power tools. The actual load may be higher
or lower depending on operating conditions, the
condition of the power tool or the accessories used.
Please allow for breaks and periods when the load
is lower for assessment purposes. Arrange
protective measures for the user, such as
organisational measures based on the adjusted
estimates.
