Overload Protection
To protect the user, motor and drill bit, the EHD 1300 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.
Care and Maintenance
Before the beginning of the maintenance- or repair works
you have to disconnect plug from the mains.
It is a must to unplug the tool before starting any service or repair works.
Repairs may be executed only by appropriately qualified and experienced
personnel.
After every repair, the unit has to be checked by an electrical specialist.
According to its design, the tool requires a minimum of care and
maintenance. However, the following maintenance works and component
checks have to be performed in regular intervals:
The electric tool as well as the ventilation slots always has to be
clean.
During work, please pay attention that no foreign elements get into
the interior of the machine.
