Switching On And Off - Metabo MFE 40 Mode D'emploi

- Press the spindle locking button (7), (with the
other hand) rotate the front diamond cut-off wheel
(18) slowly until the spindle locking button
engages perceptibly and
- with the pressed spindle locking button (7)
unscrew the clamping nut (17) with the supplied 2-
hole spanner (anti-clockwise).
The clamping flange (19) must always be fitted onto
the spindle with the sheath facing out (as shown in
the pictures (A) – (F). Pay attention that the
clamping flange (19), in relation to the spindle,
cannot be turned.
Fit the diamond cut-off wheels and pay
attention to the correct direction of
rotation. The direction of rotation is specified by
arrows (16) on the diamond cut-off wheels and on
the guard (15).
Arrangement of the spacer rings (20) and the
diamond cut-off wheels (according to desired
groove width) as in the pictures (A) – (E).
Note: Using the machine with only one diamond
cut-off wheel:
If you remove the front diamond cut-off wheel and
leave only the rear wheel on the machine, the wall
chaser is then suited for cutting through materials
(e.g. tiles).
(See page 3, fig. F.).
Note: (see page 3, fig. G.) Use of the machine with
a diamond cutting disc (see chapter 10.
accessories):
To be able to attach the diamond cutting disc, you
must remove the clamping flange (19) from the
spindle and remove from the guard (15). Now put
the diamond cutting disc on the clamping flange
(19), insert from below into the guard and put onto
the spindle. Pay attention that the clamping flange
(19), in relation to the spindle, cannot be turned. Put
on spacer rings (20) as shown in image (G).
Lock the spindle by pressing the spindle locking
button (7) and tighten the clamping nut (17) with the
two-hole wrench (14) (clock-wise direction).
Carry out a test run: Set min. cutting depth
(see chapter5.3). Position yourself and
bystanders away from the plane of the rotating
wheel and run the power tool at maximum no-load
speed for one minute. Damaged wheels will
normally break apart during this test time. Stop
immediately if significant vibrations occur or if other
defects are noted. If such a situation occurs, check
the machine to determine the cause.
5.3 Setting cutting depth
After undoing the clamping lever (4) you can set the
desired cutting depth using the scale (3).
Retighten the clamping lever (4).
Note: If required, the position / the clamping force of
the clamping lever (4) must be changed. To do this,
pull out the lever a bit, turn the lever and lower again
(see fig. A, page 2).
5.4 Attaching the dust extraction
Caution! Never work without a dust extraction
device. Dusts can be harmful to health!
Never work without a dust extraction device.
The motor can quickly choke on stone dust.
Use a suitable Metabo vacuum cleaner.
Use only anti-static suction hoses.
To extract the stone dust generated when working
with the wall chaser, put the suction hose
631370000 (4 m) onto the extraction nozzle (8).
6. Use
6.1

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.
Torque activation:
Switching on: Slide the lock (1) in the direction of the
arrow and press the trigger switch (2).
Switching off: release the trigger switch (2).
Continuous operation:
Switching on: Slide the lock (1) in the direction of the
arrow, press the trigger switch (2) and keep
it pressed. The machine is now switched on.
Now slide the lock (1) in the direction of the
arrow once more to lock the trigger switch (2)
(continuous operation).
Switching off: Press the trigger switch (2) and
release.
6.2 Working With the Wall Chaser
Always guide the machine with both hands on
the handles (12) and (13).
On the guard there are markings (6). The markings
are in the extension of the rear diamond cutting disc
and serve - when cutting grooves - as cutting
indicator.
Place the wall chaser (with the motor switched on)
with the support wheels (9) on the surface into
which a groove is to be cut, and slowly guide down
until the set cutting depth has been reached.
Then push the machine in cutting direction
