chine does not restart automatically. Upon return of
the voltage, the machine must be switched on again.
Machine stops during
planing.
Planing blade blunt/worn
Overload switch has tripped
Check microswitch
Too much chip removal
Too fast feed
Replace or sharpen blade
Switch on the motor again once it has cooled
Fit the chip extractor hood or bench lock so that the
microswitch is pressed.
Reduce chip removal.
Reduce infeed speed.
Workpiece jams during
thicknessing
Cutting depth too great Reduce cutting depth and machine the workpiece in
several passes
Speed decreases when
planing
Too much chip removal
Too fast feed
Blunt knives.
Reduce chip removal.

Unsatisfactory surface
nish
Planing blade blunt/worn
Planing blade lled with chips

Feed the workpiece with constant pressure and at
reduced speed
Machined surface too
rough
Workpiece contains too much
moisture
Dry workpiece
Machined surface
cracked
Workpiece was machined against
the grain
Too much material planed at one
pass
Machine the workpiece from the opposite direction
Machine the workpiece in several passes
Workpiece speed too
low during thicknessing
Workpiece was machined against
the grain
Too much material planed at one
pass
Clean bench top and apply a thin coating of lubricant
wax
Repair transport rollers
Set the lever for the thicknessing setting to the top
position
When thicknessing,
chip ejection obstructed
(without dust extractor).
Too much chip removal
Blunt knives.
Wood too humid.
Reduce chip removal.
Replace knives
Dry workpiece
When surface planing,
chip ejection obstructed
(without dust extractor)
Too much chip removal
Too fast feed
Blunt knives.
Wood too humid.
Reduce chip removal.
Reduce infeed speed.
Replace knives.
Dry workpiece
With surface planing
