Dust Extraction / Dust Protection
Dust generated during work is harmful to your health. That is why it is advisable to
use a vacuum cleaner and to wear a dust mask on dry drilling.
The use of dust extraction is also a prerequisite for optimum cutting performance
of the drill bit (air cooling). For the selection of suitable drill bits for different
materials, please refer to the specifications of the drill bit manufacturer.
CAUTION
When working, always guide the vacuum cleaner hose away to the rear of the
machine so that it cannot come into contact with the core bit.
CAUTION
Please read the operating instructions for the vacuum cleaner for information
about disposal of the material collected.
NOTE
To avoid electrostatic effects, use an anti-static vacuum cleaner.
Dust from material such as paint containing lead, some wood species, minerals
and metal may be harmful. Contact with or inhalation of the dust may cause
allergic reactions and/or respiratory diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood conditioning (chromate, wood
preservative).
Material containing asbestos must only be treated by specialists.
•
Use a dust extraction device if possible.
•
To achieve a high level of dust collection, use an industrial vacuum cleaner
(category M) for wood and/or mineral dust together with this tool.
•
The work place must be well ventilated.
•
The use of a dust mask of filter class P2 is recommended.
Overload Protection / Safety Clutch
To protect the user, motor and drill bit the power tool is equipped with a
mechanical and thermal overload protection.
Mechanical:
In case of sudden jamming of the drill bit, the drill spindle is
decoupled from the motor by means of a slip clutch.
The safety clutch served for compensation of shocks and
overload. To keep its functionability, it should not slip for more
than 2 seconds. In case of excessive wearing, it can be replaced
by an authorized service centre.
