Open the keyed chuck (13) by turning it until the tool can be inserted. Insert the tool.

Insert the chuck key (12) into the corresponding holes of the keyed chuck (13) and clamp the tool evenly.

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" selector switch (4) is always set to the "drilling" symbol.
