Malfunction
Cause/
possible effects
Solution
Spindle constantly changes
direction of rotation,
recognizable on the control
panel, LEDs jump back and
forth. • Operation error, sequential error,
drilling depth stop is released and is
in the lowest position in the tapping
operating mode. • Adjust the drilling depth setting at
the appropriate height and clamp
tightly. Only then switch to the
tapping operating mode.
Motor is hot • Wrong electrical connection •

Machine does not turn on. • Spindle protection switch function
• Drill drift switch function
• Switch function of motor protection
switch
• 400V connection rotating field
• Close the spindle protection, check
the switch function of the spindle
guard.
• Pull out the drill drift, check the drill
drift switch function.
• Determine the cause of the motor
overload.
• Check the rotating field.
Noise during work. • Spindle is too little lubricated
• Tool is blunt or wrongly clamped
• Oil level transmission too low
• Lubricate spindle (only possible
when disassembled)
• Use new tool and check tension
(fixed setting of the bit, drill chuck
and taper mandril)
• Check transmission oil level, top up
if necessary. Check the condition of
the gear wheels over the sight
cover.
Bit „burnt“ • Drill speed too high /feed too high
• Chips do not come out of the drill
hole.
• Drill blunt
• No or too little cooling
• Select another speed
• Extract drill more often during work
• Sharpen or
use new drill
• 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
Drill is defective • No base / support used. • Use support and clamp it with the
workpiece
Drill is running non-round or
shaking • Bit deformed
• Bearing worn down
• Drill is not correctly clamped.
• Drill chuck defective
• Use new drill
• Have the spindle bearings replaced
• Correctly clamp drill
• Replace the drill chuck
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 surface of the drill spindle
• Positioning the follower in the drill
spindle is not considered
• Clean surfaces well
• Keep surfaces free of grease
