Working With Position Indicator (For Kss-Guiding Device And F-Rail); Working With The Lateral Stop 625 In Combination With Kss-Guiding Device; Service And Maintenance; Storage - Mafell NFU 50 Traduction De La Notice D'emploi Originale

5.11 Working with position indicator (for KSS-
guiding device and F-rail)
Use position indicator 29 (Fig. 3) to
align the KSS-guiding device. The
position indicator shows the right
side of the milling cutter, set the
position indicator to the same angle
as the machine. The position
indicator is enclosed with the
machine.
Follow the procedure below:

Fasten the position indicator 29 with the wing
bolts 9 (Fig. 3).

Set the position indicator 29 to the same angle
as the machine tilt. You can also determine the
position of position indicator 29 by means of an
auxiliary milling groove in the tool.

The angle scaling refers to the right side of the
milling head.

Set the required milling depth and machine the
workpiece.
5.12 Working with the lateral stop 625 in
combination with KSS-guiding device
The lateral stop 50 (Fig. 4) is used to work parallel to
an already existing groove. Lock the stop in the guide
groove of the KSS-rail. The lateral stop is preset to
approximately 625 mm, fine adjustment at the stop is
possible.
Follow the procedure below:

Unfasten the locking screw 53 with the wrench
AF 5 that is kept on the position indicator.

Turn the adjusting
corresponding direction.

Retighten the locking screw 53.

Service and maintenance

Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.
screw 54 in the
-32-
The ball bearings used are greased for life. When the
machine has been in operation for a longer period of
time, we recommend to hand the machine in at an
authorised MAFELL customer service shop for
inspection.
Only use our special grease, order No. 049040 (1 kg
tin) for all greasing points.
Check the braking effect of your machine at regular
intervals. If the braking effect worsens, always
contact your MAFELL after-sales service to have the
braking system serviced.
In order to check the safety functions, the machine
must be handed in at a MAFELL service workshop for
inspection at the latest after 3 years of use.

6.1 Storage

If the machine is not used for a longer period of time,
it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
Store the machine only in dry rooms and protect it
from the effects of weather.

6.2 Tools

The milling heads used on the machine should be
regularly deresinified, as clean tools improve the
cutting quality.
Deresinify them by placing them in petroleum or a
commercially available deresinification agent for 24
hours.
Aluminium tools may only be
deresinified with solvents which do
not corrode the aluminium.
Promptly replace damaged clamping screws and
cutting elements.
The design of progressive tools must not be modified
during maintenance.

6.3 Tools of older machine types

Please request the installation instructions adjustable
groove cutter, Art.-No. 170650, if you intend to use
the adjustable groove cutter of the NFU 32 (Art.-No.
091418) in the NFU 50.
