5.4.1 Optical display of the remaining runtime
Triggering of the overload protection during operation leads to breakage of the milling tool, damage to the
workpiece or even damage to the portal system. You can prevent this by paying attention to the visual output
signals at the setting wheel X (Fig. 2).
As long as the power tool is not overloaded in terms of performance, the setting wheel lights up permanently in
blue (BU).
If the power tool is overloaded, the calculated remaining runtime is displayed flashing in red (RD). On page 6
(Fig. 7) you can see the temporal arrangement of the pulses in overload mode. The correlation between the
flashing behaviour and the associated remaining runtime is shown in the bottom table 4 on page 29.
If the remaining runtime is not sufficient for your application, reduce the load or feed rate to be able to switch
back to continuous operation.
5.4.2 Display of the remaining runtime in the PV design
If the power tool is in "portal mode", the remaining runtime can be queried via the PV interface in addition to the
visual display.
The bottom table shows the correlation between the remaining runtime and the associated output variables.

Service and maintenance

MAFELL machines are designed to be low in maintenance.
Replace the carbon brushes at the latest after 125 - 150 operating hours. The spare parts can be referenced in
chapter 9.
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.

6.1 Storage

If the power tool is not used for a longer period of time, it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor. Close the portal connector with the supplied covering cap Z (Fig. 4).
