Press the button for depth stop adjustment (10) and insert
the depth stop into the auxiliary handle .
The fluting on the depth stop (13) must face downwards.
Pull the depth stop far enough out that the distance between
the drill bit tip and the edge of the depth stop corresponds
to the required drilling depth X.
Changing the Tool
Keyless Chuck (see figure B)
Hold the rear sleeve (3) of the keyless chuck (1) firmly and
turn the front sleeve (2) in the rotational direction ➊ until
the tool can be inserted. Insert the tool.
Hold the rear sleeve (3) of the keyless chuck (1) and firmly
tighten the front sleeve (2) by hand in the rotational direc-
tion ➋ until it stops clicking. This will automatically lock the
drill chuck.
The lock will disengage again if you turn the front sleeve (2)
in the opposite direction to remove the tool.
Screwdriving Tools (see figure C)
You should always use a universal bit holder (14) when using
screwdriver bits (15). Only use screwdriver bits that fit the
screw head.
For screwdriving, make sure the "drilling/impact drilling" se-
lector switch (4) is always set to the "drilling" symbol.
Changing the drill chuck
Removing the drill chuck (see figure F)
To remove the keyless chuck (1), clamp a hex key (16) in
the keyless chuck (1) and position an open-ended spanner
(17) (width across flats: 12) against the spanner flat of the
drive spindle.
Place the power tool on a firm surface, e.g. a work bench.
Hold the open-ended spanner (17) in place and loosen the
keyless chuck (1) by turning the hex key (16) in the rota-
tional direction ➊. A tightly seated keyless chuck can be
loosened with a light blow on the long shaft of the hex
key (16). Remove the hex key from the keyless chuck and
completely unscrew the keyless chuck from the power tool.
Fitting the drill chuck (see figure G)
To fit the keyless chuck/keyed chuck, perform the same
steps in reverse order.
The drill chuck must be tightened using a tight-

u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
