Setting / Adjustment; Mains Connection; Chip Extraction; Clamping Of Milling Cutters - Mafell LO 65 Ec Originalbetriebsanleitung

Instructions on operation:
- Never reach into the working range of the milling
cutter or underneath the base plate while the
machine is running.
- Firmly hold onto the machine with both hands
already before switching it on.
- Whenever possible, secure the workpiece against
slipping, e.g. with screw clamps.
- Milling cutters must be replaced in good time, as
blunt milling cutters do not only increase the
danger of backlash, but also place an unnecessary
strain on the motor. The milling cutters must be
clamped in accordance with 4.3.
- Examine the workpiece for foreign objects. Do not
mill into metal parts, e.g. nails (danger of
backlash).
- The power plug must be pulled before replacing
tools, making adjustments
malfunctions (this also comprises removing
jammed chips).
Instructions on service and maintenance:
- Regularly cleaning the machine, especially the
adjusting devices and guides, constitutes an
important safety factor.
- Only original MAFELL spare parts and accessories
may be used. Otherwise the manufacturer will not
accept any warranty claims and cannot be held
liable.

Setting / Adjustment

4.1 Mains connection

Prior to commissioning make sure that the mains
voltage complies with the operating voltage stated on
the machine's rating plate.
4.2 Chip extraction (see Fig. 6)
Connect the machine to a suitable external dust
extractor during all work generating a considerable
amount of dust. The air velocity must be at least 20
m/s (65.6 ft / sec.).
The internal diameter of hose connector is 35 mm ( 1
3/8 in.).
4.2.1 Assembly of the extraction hood
Place extraction hood 505 onto base plate 3 and turn
it clockwise until it engages.
4.2.2
Press ratchet lever 4 and turn extraction hood 505
anticlockwise.
4.3 Clamping of milling cutters (see Fig. 1 and 2)
The machine can be placed onto the motor cover to
make replacing the milling cutter easier. The router is
equipped with a precision collet Ø 8 mm (Ø 1/2" on
model GB). It is possible to fasten milling cutters with
corresponding shaft diameter in this collet. The
adapter that is included in the supply facilitates the
fastening of milling cutters with female thread M 12 x
1.

4.4 Collet change (see Fig. 3)
Turn cap nut 37 from cutter spindle 27 to replace the
collet. The collet 510 hangs in the cap nut. You can
release the collet from the cap nut by forceful tilting
and pulling. Forceful pushing causes the collet to
engage audibly in the cap nut.

Disassembly of the extraction hood
Never tighten the cap nut without
fitted tool as this may damage the
collet.
Push the clean milling cutter shaft A as far as
possible into the open collet 510.
Push the index bolt 31 to lock the cutter spindle
27.
Tighten cap nut 37 by first turning it clockwise
by hand and afterwards by means of a flat
spanner of wrench size 22. It is not necessary to
regrip with the flat spanner. Simply turn back the
cutter spindle by 90° after you have unscrewed
the index bolt and relock it with the index bolt.
Reverse order as for clamping.
Before installing it, clean the cutter
spindle cone and the collet. Only
mount collets in the cutter spindle
that have engaged correctly in the
cap nut.
