Setting / Adjustment; Mains Connection; Chip Extraction - Mafell NFU 50 Manual De Instrucciones Original

Danger
The warning light 25 (Fig. 1)
indicates the rotation of the tool by
means of an "orange" signal. The
warning light 25 switches off when
the tool is stationary. As long as the
signal glows, you may not lift the
machine off the workpiece or pull it
back in the workpiece.
- Switch off the machine and let the milling head
come to a standstill before making various angle
and height adjustments on the machine.
- Do not place the machine onto the workbench
or floor without the mobile lower guard
covering the tool. An unguarded, coasting tool
moves the machine opposite to the milling
direction and may injure you. Keep in mind the
tool's coasting time (warning light).
- Do not clamp the mobile lower guard or remove
any protective parts. Please note that the mobile
lower guard consists of two parts - the lower guard
and the side access protection.
- Prior to every use, check whether the mobile
lower guard is closing properly. Do not use the
machine if the mobile lower guard is not freely
movable and does not close immediately. If the
machine is dropped inadvertently, the mobile lower
guard can get bent. Open the mobile lower guard
with the pre-feed lever 1 (Fig. 3) and ensure that it
moves freely and touches neither the tool nor other
parts irrespective of the milling angle and depth.
- Check the function of the spring for the mobile
lower guard. Have the machine serviced prior
to use if the mobile lower guard and spring do
not work properly. Damaged parts, sticky
deposits or accumulated chips will cause the
mobile lower guard to operate with a delay.
- Only open the mobile lower guard with the pre-
feed lever for special types of milling, such as
angled milling. Open the mobile lower guard
using the pre-feed lever and release the lever
as soon as the tool has penetrated the
workpiece. During all other milling work, the
mobile lower guard opens automatically.
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

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 air velocity must be at least 20
m/s (65.6 ft / sec.).
The inside diameter of the hose connector 3 (Fig. 1)
is 58 mm (2 9/32 in.).
The extraction nozzle can be rotated through 360°. It
can thus be brought into the most favourable position
for extraction. If you operate the machine without
extraction, bring the extraction nozzle into a position
where the chips are guided away from your working
position.
