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.

8 Tips and Tricks
In the case of deep bores pull the drill bit out of the
bore from time to time in order to remove the stone
dust or shavings.
Drill tiles and other brittle materials without impact.
Switch on the impulse function (SBE 900 Impuls
only) for drilling without a centre punch.
The drill chuck can be removed for screwdriving.
Insert screwdriver bit directly into the spindle's
hexagon socket. If a bit clamping bush (order no.
6.31281) is fitted, the screwdriver bit is held in
position.
For thread tapping (except SB 710), apply some oil
to the tap. Select a low speed and the first gear.
Start cutting in clockwise direction, stop and turn
out in counter-clockwise direction.
9 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.
10 Troubleshooting
If it is not possible to press in the trigger (13), check
if the rotation selector switch (11) is fully at position
R or L (except SB 710).
