ENGLISH
If the chuck is very tightly secured, disconnect from
mains. Hold the chuck using an open-end spanner
at the flats on its head, and turn the sleeve
vigourously in the direction of the arrow -1-.
Clamping the tool
- Insert the tool -2- as far as it will go.
- Grip the retaining ring and, using the other hand,
rotate the sleeve in the direction of the arrow -3-
until the mechanical resistance which can be felt is
overcome.
- Caution! The tool is not yet fully clamped!
Keep turning the sleeve (it must "click" when
turning) until it cannot be turned any further - only
now is the tool securely clamped.
In the case of a soft tool shank, retightening may be
required after a short period of drilling.

Tool change with a geared chuck (3)
See illustrations B on page 2.
Opening the chuck: Opening a geared chuck with
the chuck key -1-.
Clamping the tool: Insert tool -2- as far as it will go
and tighten equally in all 3 bores using the chuck
key -3-.
6.9
Unscrew the chuck (when driving screws
without the chuck or for use with attach-
ments)
See illustrations A, B, on page 3.
Note for Fig. A, B: Release by tapping lightly with a
rubber hammer, as shown, and unscrew.
Note: If a bit clamping bush (order no. 6.31281) is
attached, the screwdriver bit inserted in the
hexagon socket of the spindle is held in place.
7. Cleaning, Maintenance
Cleaning the keyless chuck:
After prolonged use hold the chuck vertically, with
the opening facing down, and fully open and close it
several times. The dust collected falls from the
opening. Regular use of cleaning spray on the jaws
and jaw openings is recommended.
8. Accessories
Use only genuine Metabo accessories.
Use only accessories which 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.
For a complete range of accessories, see
www.metabo.com or the main catalogue.
9. Repairs
Repairs to electrical tools must be carried out
by qualified electricians ONLY!

A defective mains cable must only be replaced with
a special, original mains cable from metabo, which
is available only from the Metabo service.
If you have Metabo electrical tools that require
repairs, please contact your Metabo service centre.
For addresses see www.metabo.com.
You can download spare parts lists from
www.metabo.com.
10. Environmental Protection
Observe national regulations on environmentally
compatible disposal and on the recycling of disused
machines, packaging and accessories.
Packaging materials must be disposed of according
to their labelling in accordance with municipal
guidelines. Further information can be found at
www.metabo.com in the "Service" section.

The technical specifications quoted are subject to
tolerances (in compliance with the relevant valid
standards).
* Energy-rich, high-frequency interference can cause
fluctuations in speed. The fluctuations disappear,
however, as soon as the interference fades away.
Emission values
Using these values, you can estimate the emis-
sions 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 organisa-
tional steps that must be put in place.
Vibration total value (vector sum of three directions)
determined in accordance with EN 62841:
