Changing the Tool (see figure C)
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
The drill spindle is locked when the On/Off
switch 11 is not pressed. This makes quick, con-
venient and easy changing of the tool in the drill
chuck possible.
Open the keyless chuck 2 by turning in rotation
direction , until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 2
by hand in rotation direction
cally locks the drill chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direc-
tion.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
