15. Troubleshooting
Fault Possible cause Remedy
The machine will
not switch on
Mains voltage is not available. Check power supply
Carbon brushes worn Contact the customer service workshop
Chip extraction not mounted Mount chip extraction
Machine without
any function or it
suddenly stops
Power failure Check fuse / overload protection
Motor or switch faulty
Have the motor or switch checked by a qualied electri-
cian.
Check micro switch
Mount the chip extractor in such a way that the micro
switch is started. Check fuse on the mains side. Due to
the built-in undervoltage protection, the machine does not
restart by itself and must be switched on again when the
voltage is restored.
Machine stops
when planing
Planing blade is blunt/worn Change or sharpen blade
Overload switch has triggered Switch back on engine after cool-down time
Check micro switch
Mount the chip suction hood or table locking mechanism
in such a way that the micro switch is started.
High degree of chip take-o Reduce chip take-o
Feed to high Reduce the feed speed
Workpiece
jammes when
planing thick-
nesser
Cutting depth to deep
Reduce cutting depth and process workpiece in several
working steps
Speed reduces
when planing
High degree of chip take-o Reduce chip take-o
Feed to high Reduce the feed speed
Blades are blunt Change blades
Unsatised
surface result
Planing blade is blunt/worn Change or sharpen blade
Planing blade has too many
chips
Remove chips
Uneven feed
Feed the workpiece with constant pressure and reduced
feed speed
Processed sur-
face too rough
Workpiece is too wet Use a dry workpiece
Processed sur-
face cracked
Workpiece has been processed
against the direction of growth
Process the workpiece from the opposite direction
Too much material planed o
at once
Process the workpiece in several operations
