Working According To Tracings With Kss-Guiding Device; 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 - Mafell NFU 50 Originalbetriebsanleitung

5.10 Working according to tracings with KSS-
guiding device

Secure the workpiece against movement.

Hold the machine by the handle and push the
two stop cams against the workpiece. Place the
front part of the KSS-guiding device onto the
workpiece.

Set the milling depth and switch on the cross-cut
milling system (See 5.2 Switching on and off,
page 26).

Slide the machine evenly forward in milling
direction.

At the end of milling, switch off the cross-cut
milling system by releasing the shift lever 8 (Fig.
1).

Wait until the milling tool is completely
stationary, then pull the machine back to its
starting position while it rests on the workpiece
and remove it from the workpiece in this
position. This guarantees that the mobile guard
28 (Fig. 3) is completely closed.
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. Now you can
pull the machine back into the
starting position. As long as the
signal glows, you may not lift the
machine off the workpiece or pull it
back.
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.

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
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.
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.
