Speed setting MAB 480:
The machines are provided with a gear with two mechanical gear
stages and full-wave control electronics.
First, make the correct mechanical setting and then adjust the exact
speed by means of the electronic speed control.
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 MAB 480:
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.
Drilling:
Drilling with core drills does not require any great expenditure of force.
Drill without great pressure.
Make sure that the chips are removed upwards.
Please, break the chip in case of greater drilling depths.
A greater pressure does not speed up drilling, the drilling machine will
be worn out quicker and the machine will be overloaded.
Always use cooling lubricating device, which is part of the delivery.
The service life of the tool depends on the lubrication!
Permanent internal lubrication with high performance cutting oil BDS
5000 is a must.
The lubricating device must not be used in the case of overhead work.
In such a case, please use BDS high performance lubrication spray
ZHS 400.
Prior to drilling, spray the grease into the inside of the drill.
Spraying must be repeated in the case of greater drilling depths.
