15. Troubleshooting
Fault
Possible cause
Mains voltage is not available.
The machine will
Carbon brushes worn
not switch on
Chip extraction not mounted
Power failure
Motor or switch faulty
Machine without
any function or it
suddenly stops
Check micro switch
Planing blade is blunt/worn
Overload switch has triggered
Machine stops
Check micro switch
when planing
High degree of chip take-off
Feed to high
Workpiece
jammes when
Cutting depth to deep
planing thick-
nesser
High degree of chip take-off
Speed reduces
Feed to high
when planing
Blades are blunt
Planing blade is blunt/worn
Planing blade has too many
Unsatisfied
chips
surface result
Uneven feed
Processed sur-
Workpiece is too wet
face too rough
Workpiece has been processed
against the direction of growth

face cracked
Too much material planed off
at once
Remedy
Check power supply
Contact the customer service workshop
Mount chip extraction
Check fuse / overload protection
Have the motor or switch checked by a qualified electri-
cian.
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.
Change or sharpen blade
Switch back on engine after cool-down time
Mount the chip suction hood or table locking mechanism
in such a way that the micro switch is started.
Reduce chip take-off
Reduce the feed speed
Reduce cutting depth and process workpiece in several
working steps
Reduce chip take-off
Reduce the feed speed
Change blades
Change or sharpen blade
Remove chips
Feed the workpiece with constant pressure and reduced
feed speed
Use a dry workpiece
Process the workpiece from the opposite direction
Process the workpiece in several operations
