The entire handle heating system is
maintenance-free and subject to
practically no wear. Faults in the
generator, heating elements and
wiring are generally caused by
mechanical damage.
Important:
The heating element in the rear
handle (arrow) may overheat and
fail if it is not bonded firmly in
position, i.e. completely flat without
creases.
