13 Disposal, recycling of used devices
In your own interest and for the benefit of the
environment, please always dispose of any machine
components at designated and approved facilities.
13.1 Decommissioning
Immediately decommission used machines in order to
avoid later misuse and endangering of the environment
or of persons.
Step 1: Eliminate all environmentally hazardous
operating materials from the used device.
Step 2: If required, disassemble the machine into easy-
to-handle and usable components and parts.
Step 3: Supply the machine components and operating
materials to the provided disposal routes.
13.2 Disposing of electrical devices
Please note that electrical devices contain a large
number of recyclable materials as well as
environmentally hazardous components.
Please ensure that these components are disposed of
separately and professionally. In case of doubt, please
contact your local municipal waste management
authority.
For the recycling process, please request the assistance
of a specialized waste disposal centre if required.
13.3 Disposal of lubricants
The manufacturer of the lubricant makes the disposal
instructions for the used lubricants available. If
necessary, request the product-specific data sheets.
Failures Possible cause Elimination
Machine does not
switch on.
1. No mains voltage,
Connection cable is defective.
2. Motor protection switch has
triggered.
3. Carbon brushes worn.
1. Have the power connection checked by
qualified personnel.
2. Leave the motor to cool and then
attempt to start it again.
3. Take the machine to a customer
service workshop.
The machine switches off
automatically during
operation.
Power failure. 1. Check the fuse.
2. The integral undervoltage protection
prevents the machine from restarting
automatically, so it must be switched
on again manually when the voltage
returns.
The machine stops while
machining the workpiece.
Safety device has triggered due to a
blunt blade or excessive feed rate.
Before continuing work, replace the cutter
or wait for the motor to cool down.
The speed decreases while
the workpiece is being
machined.
1. Excessive chip removal rate.
2. Excessive feed rate.
3. Blunt cutter.
4. Power failure, faulty fuses.
1. Reduce the chip removal volume.
2. Decrease the feed rate.
3. Replace the cutter.
4. Check the fuses. Have qualified
personnel replace the faulty fuses.
Milling pattern is not clean. 1. Blunt cutter.
2. Workpiece fed in erratically.
1. Replace the cutter.
2. Machine the workpiece with a constant
pressure and at a reduced feed rate.
Chip discharge point clogged
(no extraction).
1. Excessive chip removal rate.
2. Blunt cutter. Wood is too wet.
1. Reduce the chip removal volume.
2. Replace the cutter.
