Setting / Adjustment; Mains Connection; Chip Extraction; Installation Of Double-Toothed Belt - Mafell 919620 Originalbetriebsanleitung

- The machine is a one-man tool and may only be
used for work during which the base plate 3 serves
as workplate.
- Keep a firm hold on the machine already before
switching it on and support it. At the same time, the
saw wire must be unobstructed. Start cutting the
workpiece only once the wire has reached its full
speed. Pay attention to a secure footing.
- The switch may not be wedged in ON position.
- Never reach below the base plate or into the chip
ejector during sawing.
- Never transport the machine with running saw wire
and pay attention that, except for the workpiece,
the running saw wire does not come in contact with
any adjacent objects.
- Never remove the cover 5 (Fig. 2) that covers the
drive wheel while the machine is running; only
remove the cover for a tool change and refit it
immediately afterwards.
- The machine must be guided so that the pressure
exercised during cutting does not cause the speed
to drop.
- If possible, use a limit stop or a straight edge guide
for cutting.
- Examine the workpiece for foreign objects. Never
attempt to cut into metal objects (e.g. nails) or
adhering sand.
- Always lead the connecting cable away from the
machine to the rear while sawing.
- Immediately pull the power plug in case of
damaged or severed connecting cables.
- Match the feed speed during sawing to the
material thickness. Pushing forward too quickly
leads to motor overload, irregular saw cuts and
quick dulling of the saw wire.
- Remove the machine from the workpiece only after
the saw wire has come to a standstill. Thanks to
the built-in brake, this happens very quickly.
Instructions on service and maintenance:
- Regular cleaning of the machine, in particular the
setting mechanisms for swivelling the guides for
the supplementary support plate and the enclosure
of the top and bottom wire deflection, constitutes
an important safety factor. Pull the plug before
starting this work.
- 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

Danger
Substances that are harmful to
health must be taken up with an M-
suction device.
Connect the machine to a suitable external dust
extractor during all work generating a considerable
amount of dust. The high volume vacuum cleaner S
200 M (see chapter optional accessories) is optimally
suited for this. The air velocity must be at least 20 m/s
(65.6 ft/sec.).
The inside diameter of the hose connector 6 (Fig. 2)
is 35 mm (1.377 in.).

4.3 Installation of double-toothed belt

Danger
Pull the machine's power plug
before installing the double-toothed
belt.
The double-toothed belt should be
fitted when working with insulation
material of a density > 160 kg/m³.

Hook the double-toothed belt with the fine
serration into the pinion 7 (Fig. 3).

Pull up the clamping lever 8 (Fig. 4) from its
parking position and turn it by 90° inwards.
Hook the double-toothed belt into the deflection
roller 30 (Fig. 6) and slowly slide the clamping
lever down.
