7.8 Tool change with keyless chuck
Use the keyless chuck when non-impact drilling in

Tighten the tool (see page 2, fig. B):
Turn sleeve (2) in direction "AUF, RELEASE" (a).
Insert tool as deeply as possible (b) and turn sleeve
in the opposite direction, until any perceptible
mechanical resistance is overcome (c). 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 securely clamped.
.
With a soft tool shank, retightening may be required
after a short period of operation.
Note: The grating sound that may be heard after the
drill chuck is opened is purely functional; it is
stopped by turning the sleeve in the opposite direc-
tion.
If the chuck is extremely tight: remove the battery
pack from the machine. Hold the drill chuck at the
drill chuck head using an open-end spanner and
turn the sleeve (2) vigorously in the direction
"OPEN, RELEASE".
7.9 Metabo VibraTech (MVT)
For reduced vibrations and less stress on the
hands.
Always apply a moderate amount of pressure to the
handle when pushing down the machine and do not
force. Vibrations are reduced most effectively at the
central position (9).
8. Maintenance, cleaning
- Ventilation slits:
Clean the ventilation slits on the machine occa-
sionally.
- Remove the battery pack periodically and wipe
the contact area of the battery pack and machine
with a dry cloth and remove drilling dust.
- Always keep the spindle (6) clean and apply a
light coating of grease. (Special grease: Order
No.: 6.31800)
- Keyless chuck (1) cleaning:
After prolonged use, hold the chuck vertically, with
the opening facing down, and fully close it and
open it several times. The dust collected falls from
the opening. The application of cleaning spray to
the jaws and jaw openings at regular intervals is
recommended.
