Example:
Desired speed = 270 min -¹
Set the left gear selector switch upwards to the speed range of 370
min-¹.
Set the right gear selector switch upwards to the speed range of 370
min-¹.
Set the electronic speed control Speed to stage 4.
If possible, always select a setting with low transmission ratio and high
motor speed!
Thus the motor is set with a high torque and is protected against
overheating under heavy load.
Thermal protection:
The thermal protection automatically switches the motor off in case of
overheating. Then let the motor run at high speed and no load for about
2 minutes in order to cool down.
Torque setting:
Torque setting can be electronically controlled by means of the rotary
switch Power. If the setting is reduced, the machine will switch off in
the case of increased load. It is recommended to test this during the
first applications so that drill breakage is avoided is the user is
unskilled.
After switching-off, key 0 on the motor switch must be actuated first,
and then key I in order to start the machine again.
