4.3 Speed adjustment
B60S only
EUROBOOR B60S is equipped with a stepless electronic speed adjustment for the milling head.
The speed adjustment ranges from 1675 rpm (minimum) to 2850 rpm (maximum).
To adjust the speed, the speed adjustment knob needs to be rotated: completely rotated counter-
clockwise achieves minimum speed, completely rotated clockwise achieves maximum speed. Be
careful not to overturn the speed adjustment knob past the end stops.
On the machine an indicatory range of common material applications is provided. Ranging from slow
to high milling head speed:
- Exotic metals (such as Inconel, Hardox)
- Stainless steel
- Grey cast iron
- Construction steel
These indicatory material types are not exclusive, and also other metal types can be processed with
this machine. Always check the appropriate speed for the material you are working with, and try a
few settings on a test piece before starting with the actual operation.
4.4 Overload protection
B60s only
EUROBOOR B60S is equipped with overload protection.
Overload can be caused by either to fast feeding rate or to deep bevel setting.
When the overload indicator light (red) is flickering, the machine is being used at maximum
permitted load. It is best to avoid this kind of situation, as at this stage the operation is not being
performed in the fastest way. Also, the motor is still running warm with the risk of permanently
damaging its internals.
When the operation is being performed at real overload with continuously burning overload
indicator light (red), the machine will protect itself by automatically switching off the motor.
Press the motor off switch to reset the overload protection. Check the workpiece and machine and
adjust when necessary. Press the motor on switch to continue operating again.
