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.
Keyed chuck (see figure C)
Open the keyed chuck (13) by turning it until the tool can be
inserted. Insert the tool.
Insert the drill chuck key (12) into the corresponding holes
of the keyed chuck (13) and clamp the tool evenly.

u
chuck may heat up significantly when it is used for long
periods.
Screwdriving Tools (see figure D)
You should always use a universal bit holder (14) when using
screwdriver bits (15). Only use screwdriver bits that fit the

health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
