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 unintentional start-up of the machine:
always switch off the machine, if the plug is
pulled from the mains socket or if there was a power
cut / if the battery pack was removed from the
machine.
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.
Machines with slide switch:
Switching on: Push the sliding switch (5) forward.
For continuous activation, now tilt downwards until
it engages.
Switching off: Press the rear end of the slide
switch (5) and release it.
8.2 Working Directions
The speed can be preset via the thumb-wheel (7)
and is infinitely variable.
Positions 1-6 correspond approximately to the
following no-load speeds:
1 ........ 4500 / min
2 ........ 6200 / min
3 ........ 8100 / min
The VC 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/mm2 .................................. 4-6
Steel up to 600 N/mm2 .................................. 3-5
Steel up to 900 N/mm2 .................................. 2-4
Stainless steel ............................................... 1-3
The best way to determine the ideal setting is
through a practical trial.
8.3 Working Directions
Note: When machining thin sheet metal (>=0.7mm)
attach the butting ring (depending on design
variant, order no.: 3.16.06.608.0). Read the
operating instructions supplied with the butting ring.
1. Check indexable inserts (22). Change damaged
or worn indexable inserts.

6....... 11500 / min
2. Set the chamfer height (see section 7.2).
3. Always hold the machine with both hands on the
intended handles, take a secure stance and
concentrate on the work.
4. First switch on, then place the machine with the
support surface (19) onto the workpiece and
only then put the tool close to the workpiece. 5. When cutting, always work against the run of the
disc (see illustration). Otherwise there is the risk
of kickback. Cut with moderate material feed
adapted to the material to be processed or
selected speed. If the selected speed is too low
and / or if the material feed is too high, strong
vibrations can be caused (at the machine). Do
not tilt, apply excessive force or sway from side
to side.
6. Guide the machine in such a way that the parallel
guide (18) is in contact with the workpiece. If you
work without parallel guide: Guide the machine
in such a way that the ball-bearing stationary
seal ring (21) is in contact with the workpiece.
7. To finish work: Remove the tool from the
workpiece, switch off machine. Let motor come
to a stop, put down machine.
9. Maintenance
9.1 Change indexable inserts
Regularly check the holder for the indexable inserts
(24). Repair/replace damaged or worn holders for
the indexable inserts.
Regularly check all indexable inserts (22). Change
damaged or worn indexable inserts.
Remove the battery pack from the machine /
pull the plug out of the socket before making
any adjustments, changing tools, carrying out
maintenance or cleaning.
Indexable inserts, holders for indexable
inserts, workpiece and chips can be hot after
work. Wear protective gloves.
Turn/replace blunt indexable inserts or inserts
where the coating is worn in due time. Blunt
indexable inserts increase the risk of the machine
getting jammed and climb out.
Always turn or replace all indexable inserts.
Use only indexable inserts approved by
Metabo. See the Accessories Section.
1. By turning the adjustment ring (15) to the stop,
unscrew the holder for the indexable inserts (24)
as much as possible - this provides good access
to the indexable inserts.
2. Press in the spindle locking button (2) and turn
the holder for the indexable inserts (15) by hand
until the spindle locking button (2) engages.
Keep the spindle locking button (2) pressed.
3. Unscrew the fastening screw (23) and remove
the indexable insert (22).
