4.9 Overheat protection

This machine is equipped with an all-time electronic temperature protection. If the temperature of
the motor unit runs up to 70° C (158 °F) the motor unit will stop. After a few minutes it can be started
again. When it is possible to start the motor again, let the motor run idle at full speed for a couple of
minutes to let the motor cool down more in an efficient way.

4.10 Carbon brushes

This machine is equipped with carbon brushes with two protection features. The purpose of both
features is to schedule timely service and avoid additional costs by unexpected downtime or
unnecessary part replacement.
Carbon brush wear indicator
On top of the motor housing you will find an integrated LED light. Under normal circumstances this
light is off. The LED light will start burning red when the carbon brushes are worn to a level where it
is advised to replace them. Actual remaining operating time depends on the use of the machine, but
can be at least twelve operating hours. This makes it possible to schedule service of the machine and
avoid unexpected downtime.
Automatic shut-off
As additional protection, when the carbon brushes are actually worn to a level where replacement is
needed, the motor will be shut-off automatically. This prevents the armature from being damaged.
During automatic shut-off, the carbon brush wear indicator is not lit.
For replacement of carbon brushes, see chapter 6. Maintenance.
