. THE DRILLING MACHINE HAS A MODULAR DESIGN AND IS EASY TO ASSEMBLE
. THE MACHINE HAS A WATER COOLED GEARBOX WITH A PIPE THAT RUNS THROUGH THE SPINDLE
. THE DRILLING MACHINE IS EQUIPPED WITH SOFT-START AND OVERLOAD PROTECTION
. SOFT START : SOFT-START IS AN ELECTRONIC CURRENT LIMITER WHICH PROVIDES A SOFTER START . MAXIMUM SPEED IS REACHED ABOUT THREE SECONDS AFTER THE MACHINE IS TURNED ON
OVERLOAD PROTECTION : OVERLOAD PROTECTION IS AN ELECTRONIC OVERLOAD PROTECTION. IT CONSIDERS FACTORS SUCH AS RATED INPUT VOLTAGE AND AMBIENT TEMPERATURE. THIS WAY YOU CAN ALWAYS GET MAXIMUM POWER OUTPUT WITHOUT DAMAGING THE MACHINE.
IF THE MOTOR IS OVERLOADED, THE OVERLOAD PROTECTION PULSES THE MOTOR. REDUCE THE LOAD AND THE MOTOR RETURNS TO ITS NORMAL SPEED. THE OVERLOAD PROTECTION DISCONNECTS THE POWER, IF THE MACHINE IS SUBJECTED TO HEAVY LOADS OR IF THE DRILL BIT JAMS. RESET THE MACHINE BY SWITCHING IT OFF AND TURN ON AGAIN. IF THE DRILL BIT JAMS, THE MECHANICAL SLIP CLUTCH PROTECTS THE GEARBOX BEFORE THE OVERLOAD PROTECTION DISCONNECTS THE POWER.
