Overload protection
To protect the user, motor and drill bit, the SD 16E is equipped with a mechanical,
electrical and thermal overload protection.
Mechanical:
In case of sudden jamming of the drill bit, the drilling spindle is unclutched from the
motor by means of a slip clutch.
Electrical:
In case of overload due to too large feed force, the electronic will cut OFF the machine.
After discharge and switching ON you can continue drilling again.
Thermal:
In case of permanent overload, a thermocouple protects the motor against destruction.
In that case, the tool switches off and can only be restarted after a certain cooling-down
period (approx. 2 minutes). The cooling-down time depends on the temperature of the
motor winding and ambient temperature.
Safety clutch
The slip 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.
Dust protection
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.
especially in conjunction with additives for wood conditioning (chromate,
wood preservative). Material containing asbestos must only be treated by specialists.
