Initial Operation, Setting; Adjusting The Cutting Depth; Setting Speed - Metabo OFE 738 Manual Original

en ENGLISH
Observe the relevant guidelines and national
regulations for your material, staff, application and
place of application (e.g. occupational health and
safety regulations, disposal).
Collect the particles generated at the source, avoid
deposits in the surrounding area.
Use suitable accessories for special work. In this
way, fewer particles enter the environment in an
uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
- do not direct the escaping particles and the
exhaust air stream towards yourself or nearby
persons or towards dust deposits,
- use an extraction unit and/or an air purifier,
- ensure good ventilation of the workplace and keep
it clean using a vacuum cleaner. Sweeping or
blowing stirs up dust.
- Vacuum or wash protective clothing. Do not blow,
beat or brush protective gear.

6. Initial Operation, Setting

Before commissioning, check that the rated
mains voltage and mains frequency stated on
the type plate match your power supply.
Always install an RCD with a maximum trip
current of 30 mA upstream.
Pull the plug out of the plug socket before any
adjustments or servicing are performed.
6.1 Inserting the accessory
The high speed of the router requires high-
quality tools (HSS or carbide).
Only use accessories that are suited for a
speed of 34000 1/min.
Only use accessories the shaft diameter of
which matches the collet bore of the collet
chuck. Collet chucks see Chapter on Accessories.
12
The collet chuck nut may only be tightened by
hand if no accessories are used.
1. Unplug power cable;
2. Locking the milling spindle: Push spindle locking
button (12) and keep pressed.
3. Turn the collet chuck nut (11) until the slider with
the recess sits on the flats of the spindle.
4. Insert the tool with the full length of the shank in
the collet chuck (9).
5. Firmly tighten the collet chuck nut (11) using a 19
mm open-end wrench.
6. Release the spindle locking button (12).
6.2

Adjusting the cutting depth

Clean and safe cutting is achieved with a
maximum cutting depth of 6 mm.
When working with hard wood, regularly
release the machine when idle to cool the
motor sufficiently.
1. Loosen the knob handle (3) (in anti-clockwise
direction) and guide the motor part downwards
until the milling cutter sits on the workpiece.
2. Subsequently tighten the knob handle (3) again
(turn in clockwise direction).
3. Release the wing (4) screw.
4. Guide the pin (5) downwards until it rests on the
knurled screw (6) .
5. Pay attention to the scale (2), push the pin (5)
upwards and roughly set the desired cutting
depth at the scale (2).
6. Retighten the wing screw (4).
7. Fine adjustment using the knurled screw (6):
1 turn of the knurled screw corresponds to a
change in cutting depth of about 1 mm.
6.3

Setting speed

The speed can be set via the thumb-wheel (1) and
is infinitely variable.
The VC electronics keep the speed almost constant
between idle and nominal load. This eliminates the
need for manual readjustment.
Speeds when idle:
Stage 1..............................13000 1/min
Stage 2..............................18000 1/min
Stage 3..............................23000 1/min
Stage 4..............................27000 1/min
Stage 5..............................30500 1/min
Stage 6..............................34000 1/min
6.4 Attach the chip extraction
See page 2, fig. A+B.
1. When using an extraction unit, the connection
piece (8) is inserted from the front or rear into the
base plate of the router.
2. Slide the recess in the plate of the connection
piece below the nose of the base plate (front or
rear).
3. Press the connection piece with a little pressure
against the base plate.
4. Lock the fixing lever (15) below the extraction
nozzle in 90° position to the base plate.
5. To extract the saw chips, connect a suitable
extraction unit with suction hose to the
connection piece.
