2. setting process).
3. Carry out a trial cut.
4. Proceed as follows if the milling height should be
set very accurately for the last milling operation:
Carry out a trial cut. Measure the cut milling
height and adjust it by one scale mark if
necessary by turning the adjusting ring (6):
clockwise rotation = larger milling height. Anti-
clockwise rotation = lower milling height. Carry
out another trial cut. Repeat this step if
necessary.
8. Use
8.1 Switching on and off
Always guide the machine with both hands.
Switch on first, then guide the accessory
towards the workpiece.
Avoid inadvertent starts: always switch the
tool off when the plug is removed from the
mains socket or if there has been a power cut.
In continuous operation, the machine
continues running if it is forced out of your
hands. Therefore, always hold the machine with
both hands using the handles provided, stand
securely and concentrate.
Avoid the machine swirling up or taking in dust
and chips. After switching off the machine,
only place it down when the motor has come to a
standstill.
Switching on: slide the paddle switch (17) in the
direction of the arrow and then press the
paddle switch (17) (see p. 3 Fig. E).
Switching off: release the paddle switch (17).
8.2 Setting speed
The speed can be preset via the thumb-wheel (13)
and is infinitely variable.
Positions 1-6 correspond approximately to the
following no-load speeds:
1......... 8000 / min
2......... 8900 / min
3......... 9900 / min
The VTC electronics make material-compatible
work possible and an almost constant speed, even
under load.
Speed recommendations for different materials:
Aluminium, copper, brass ..............................4-6
Steel up to 400 N/mm
Steel up to 600 N/mm
Steel up to 900 N/mm
Stainless steel................................................1-3
The best way to determine the ideal setting is
through a practical trial.
8.3 General working instructions
1. Check the indexable inserts (15). Change
damaged or worn indexable inserts.
2. Fix workpiece without vibrations using clamping
devices.
4 ....... 10800 / min
5 ....... 11700 / min
6 ....... 12600 / min

3. Always hold the machine with both hands on the
designated handles, take a secure stance and
concentrate on the work.
4. The indexable inserts (15) do not touch the
workpiece. First switch on, then place the
machine with the guide rail (18) onto the
workpiece and only then put the tool close to the
workpiece.
Guide the machine evenly at a speed suitable
for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
5. Guide the machine in such a way that the guide
rail (18) is in contact with the workpiece.
6. Finishing the work: remove the tool from the
workpiece, switch off machine. Let motor come
to a stop, put down machine.
8.4 Working with the solenoid guide rail
- Fix the solenoid guide rail (18) to the left of the
metal weld bead remover.
- Using the clamping lever (21) the guide rail can be
levelled.
- Fix the magnets using the solenoid bolts (20) to fix
the solenoid guide rail.
- Work alongside the guide rail.
- After working with the guide rail, loosen the rail
using the solenoid bolts (20) by pressing and
turning in anti-clockwise direction.
- The connections (19) can be used to install further
rails to extend the ripping fence.

9. Maintenance

9.1 Changing indexable inserts
Pull the plug out of the socket before making
any adjustments, changing tools, carrying out
maintenance or cleaning.
Indexable inserts, holders for indexable
inserts, the workpiece and chips can be hot
after work. Wear protective gloves.
Regularly check the indexable insert holder (16).
Repair/replace damaged or worn indexable insert
holders.
Regularly check all indexable inserts (15). Change
damaged or worn indexable inserts.
Turn/replace blunt indexable inserts or inserts
where the coating is worn in due time. Blunt
indexable inserts increase the risk that the machine
will catch and breaks loose or that the indexable
insert plate holder (16) is damaged.
Do not use heavily worn or defective indexable
insert plates.
Always turn or replace all indexable inserts.
Use only indexable inserts approved by
Metabo. See the Accessories chapter.
