•
Switch contact faulty.
•
The power supply is faulty, plug is
loose.
•
Overload, the fuse has blown.
•
Short circuit in the electromagnet or
faulty electromagnet.
•
Magnetisability of the substrate too
low.
•
Conductor plate faulty.
•
Replace the switch.
•
Replace the cable and plug.
•
Replace the fuse.
Replace or repair the electromag-
net.
•
Check the thickness and material
properties of the substrate.
•
Replace the conductor plate
Drilling spindle does not
switch on.
•
Electromagnet is not switched on.
•
The sensor detects too little magnetic
holding force on the component.
•
Switch contact faulty.
•
Bad contact of the carbon brush.
•
Faulty rotor or stator winding.
•
Before switching on the drilling spin-
dle, first switch on the electromag-
net.
•
•
Replace the switch.
•
Replace the carbon brushes of the
electric motor.
•
Completely replace the drilling
head.
Problems on the drive motor
•
The spark colour on the electric motor
is orange.
•
Sparks are flying out.
•
Sparks are flying in a ring from fire.
•
Reduce the drilling feed.
•
Please replace the carbon brushes.
•
Check whether the rotor or stator
winding is faulty. Motor burnt out.
Drill or core hole drill "burnt
up"
•
Feed too fast.
•
Chips are not coming out of the drilled
hole.
•
Drill blunt.
•
No or too little cooling.
•
Reduce feed.
•
Extract drill more often during work.
•
Sharpen drill bit/ use a new drill bit.
•
Use cooling agent
Drill tip is running off centre,
the drilled hole is non-round
•
Hard points on the workpiece
•
Length of the cutting spirals/or angles
on the tool are unequal
•
Drill deformed
•
Use new drill
The drill chuck or the taper
mandrel cannot be inserted.
•
Dirt, grease or oil on the taper inside
of the drill chuck or on the taper sur-
face of the drill spindle
•
Positioning the follower in the drill
spindle is not considered
•
Clean surfaces well
•
Keep surfaces free of grease
