Troubleshooting
The workpiece is fed jerkily
through the machine.
1. The machine table is covered
with resin or rust.
2. One of the feed rollers has been
bent.
1. 6. Clean and lubricate the table.
2. Replace the bent feed roller.
The machine runs for a while
but then stops.
1. One of the motors, in most cases
the motor of the upper cutter, gets
overheated.
1. See the next point, ‘‘
The motor gets overheated.
1. Wood debris has accumulated in
the chassis of the machine or
around the cooling fans of the
motors.
2. Dull knives.
3. Too low voltage in the power sup-
ply.
4. Loose or bad connection in the
power supply to the machine or in
the electrical system of the
machine.
5. The upper cutter removes too
much wood.
6. The feeding speed is too high.
1. Make sure that wood debris has not
accumulated in the machine, and that
the cooling fans of the motors have free
flow. If the motors are kept clean they
will be cooled more efficiently.
2. Grind or replace the knives.
3. The electrical system may only be
opened by a qualified electrician:
Check that you have the correct voltage
on all phases.
4. The electrical system may only be
opened by a qualified electrician: First of
all, check that the connecting cable has
the correct current and voltage during
operation. Also check that all wires are
correctly connected in the electrical sys-
tem and motors of the machine.
5. If the workpiece is to wide, of a hard
sort of wood or of varying oversizes:
plane it into size before the final machin-
ing.
6. Decrease the feeding speed.
Play in the adjusting crank of
the movable side cutter.
1. The bronze bearing in the bearing
housing of the crank is defect. One
reason for this can be that the crank
has been turned when the locking
handle of the carriage is tightened.
1. Replace the bronze bearing and
remember to open the locking handle
under the table before adjusting the side
cutter.
