Switching the power tool on and off,
setting speed
Position the trigger-switch (9) as required.
The speed can be set to any value within its
range.
NB:
The noise that occurs when the machine is
switched off is due to its design and has no
effect on its operation or service life.

Rapid-action keyless chuck
Opening
Twist the sleeve (11) towards “AUF,
RELEASE”.
Clamping bit
Open the rapid-action keyless chuck and insert
the bit fully.
Twist the sleeve (11) towards “GRIP, ZU”, until
the bit is clamped tightly in the chuck.
When using soft bit shanks, it may be neces-
sary to retighten the chuck after a short period
of operation.
NB - with SBT 15.6 Plus / SB 12 Plus /
SBT 12 Plus / SB 12 Impuls:
Twist the sleeve (11) towards “GRIP, ZU” until
the mechanical resistance which can be felt is
overcome.
The bit is not yet fully tightened!
Continue to turn, exerting firm pressure (you
must hear a clicking noise as you turn) until it
cannot be turned any further - only now is the
bit safely tightened.
NB:
Once the chuck has been fully opened, a
clicking noise may be heard. This is a func-
tional characteristic and can be cancelled by
turning the sleeve in the other direction.
Removing the chuck
Open the rapid-action keyless chuck.
a Loosen the screw (13)
(NB: left-hand thread).
b Screw off the chuck (1) using an open
ended spanner (12).
Replace the chuck by reversing the above
procedure.
Cleaning
Clean from time to time by holding the tool with
the rapid-action keyless chuck facing vertically
downwards and twist the sleeve as far as it will
go towards “GRIP, ZU”, and then turn back
fully in the opposite direction (“AUF,
RELEASE”).
The dust which has accumulated will fall out of
the chuck.
Drilling

speed).
Switch on impulse mode for drilling into steel,
aluminium or tiles, with no need for preliminary
centre-punching and pilot drilling.
Driving screws
Use of 1st gear is recommended (low speed),
and with the torque control feature in opera-
tion.
When driving screws with deformed heads in
wood, switch on impulse mode.
Switch on impulse mode to achieve maximum
torque when driving screws.
Tapping threads
Apply a light film of oil to the tap.
