A
Figure A: Normal wear: turn / replace indexable
insert.
Figure B: Wear after working on hard materials: turn
/ replace turning plate. In the event of heavier wear,
do not use the indexable insert plate and instead
replace.
1. Loosen the screws (10) and slide one chip
protection plate (11) upwards.
2. Turn the indexable insert holder (16) manually if
necessary.
3. Unscrew the fastening screw (14) and remove
the indexable insert (15).
4. Clean indexable insert (15) and clamping
surfaces on the indexable insert holder (16).
5. Turn the indexable insert or replace the
indexable insert if all blades are blunt.
6. Fix again the indexable insert (15) with a
fastening screw (14). Torque: 3.5 Nm.
7. Slide the chip protection plate (11) all the way
down. Tighten the screws (10).
Note: Causes for indexable inserts with broken
corners or, in extreme cases, for broken indexable
inserts, can include:
- Impacts on the indexable insert due to incorrect
use: See chapter 8.3.
- Workpiece vibrations: Fix workpiece without
vibrations using clamping devices.
- Indexable insert not correctly fastened: Always
clean clamping surfaces and note torque.
- Indexable insert not correctly fastened: Strongly
worn Indexable inserts do not have sufficient
contact surfaces and therefore may not be
fastened sufficiently. Replace the strongly worn
indexable inserts.
10. Cleaning
Pull the mains plug out of the socket.
Chips and particles can deposit at the milling head
(16). This can lead to blockage of the milling head.
Regularly clean the milling head and its
surroundings and remove chips and particles.
Particles may become deposited inside the power
tool during operation. This impairs the cooling of the
power tool. Conductive build-up can impair the
protective insulation of the power tool and create an
electrical hazard.
16
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner. Prior to this operation,
separate the power tool from the power source and
wear protective goggles and a dust mask.

protection is active. If the mains plug is inserted with
the machine switched on or if the power supply is
restored following an interruption, the machine
does not start up. Switch the machine off and back
on again.
- Restart protection: if the mains plug is inserted
with the machine switched on or if the power
supply is restored following an interruption, the
machine does not start up. Switch the machine off
and back on again.
- Overload protection: there is a reduction in
load speed. The coil temperature is too high!
Allow the machine to run at idle speed until it has
cooled down.
- Switching on the machine briefly reduces the
voltage. Unfavourable mains power conditions
may have a detrimental effect on other machines.
Power impedances less than 0.4 ohm should not
cause malfunctions.
