7.7 Tool change with Futuro Plus keyless
chuck
(not KHE-D 24, BHE-D 24)
Insert tool. Grip the retaining ring (a) firmly and,
with the other hand, turn sleeve (b) towards "GRIP,
ZU", until the mechanical resistance which can be
felt is overcome.
Caution! The chuck is not yet fully tightened! Keep
turning (there is a "clicking" sound while turning),
until further turning is no longer possible - only now
is the tool securely tightened.
With a soft tool shank, retightening may be
required after a short period of operation.
Opening the drill chuck:
Grip the retaining ring (a) firmly and, with the other
hand, turn the sleeve (b) towards "AUF,
RELEASE".
Note:
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.
If the chuck is extremely tightened:
Unplug. Hold drill chuck with an open end spanner
at the flats on its head and turn the sleeve (b) hard
towards "AUF, RELEASE".
Only moderate pressure is required for hammer
drilling and chiselling. Exerting a high force does
not increase performance.
When drilling deep holes, remove the drill bit
periodically from the hole to release the stone
dust.
Drill tiles and other brittle materials without impact.
Keyless chuck cleaning:
After prolonged use hold the chuck vertically, with
the opening down, and fully open and close 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.
The vent slots of the machine should be cleaned
from time to time.
If the trigger (11) can not be depressed, check to
see that the direction of rotation selector switch (9)
is fully set to the R or L position.
Electronic signal indicator (8) with VTC
electronics
(KHE-D 28)
Flashing - carbon brushes worn
The carbon brushes are almost completely worn. If
the brushes are completely worn, the machine
switches off automatically. Have the brushes
replaced by an authorized service centre.
