 The battery can be damaged by pointed objects such as
nails or screwdrivers or by force applied externally. An
internal short circuit can occur and the battery can burn,
smoke, explode or overheat.
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health and cause allergic reactions, lead to res-
piratory infections and/or cancer. Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– 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
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.

it.
 The quick change chuck is automatically locked. Check the
locking effect by pulling the quick change chuck.

 When transporting and storing, set the rotational di-
rection switch to the centre position. Danger of injury
when accidentally actuating the On/Off switch.

switch is in the off position before inserting battery
pack. Carrying the power tool with your finger on the
On/Off switch or inserting the battery pack into power
tools that have the switch on invites accidents.
