Problem Possible Cause Remedy
None of the motors can be
started.
1. The cover is not entirely closed.
2. The emergency stop button is
pressed down.
3. No power is supplied to the
machine.
4. One of the motors is overheated.
5. Fault in the electrical system of
the machine.
6. A fuse has blown in the electric
box of the machine.
7. Wood debris has accumulated in
the cover’s safety switch.
1. Firmly tighten the locking knob on the
cover. You can hear a soft click when
the safety switch is activated.
2. Reset the emergency stop button by
pulling it outwards.
3. Check the residual circuit breaker and
the fuses in the building. Also check the
connecting cable.
4. Wait until the overheating protection
of the motor automatically resets (see
the point, “The motor gets overheated.
”).
5. The electrical system may only be
opened by a qualified electrician: First of
all, check the safety hold circuit. This cir-
cuit includes, among other things, the
emergency stop button and the over-
heating protections in the connection
block on each motor.
6. The machine has one or two auto-
matic fuses. Reset the fuse that has
blown. If the problem recurs, let a quali-
fied electrician find the cause of the
problem and, if necessary, replace the
fuse.
7. The electrical system may only be
opened by a qualified electrician: Open
and clean the safety switch from wood
debris.
