15. Maintenance and care
WARNING
Danger due to hot surfaces!
After frequent operation parts of the
motor carriage or the control unit may
become hot. If the cover is removed and
hot parts are touched, they may cause
burns.
► Allow the operator to cool down before
removing the cover.
NOTE
The motor carriage is supplied with safety
low voltage via the chain and the track.
The use of oil or grease will greatly reduce
the conductivity of the chain, track and
motor carriage. This may result in faults
due to inadequate electrical contact.
The chain and track are maintenance-free
and must not be oiled or greased.
NOTE
The use of unsuitable cleaning agents may
damage the surface of the operator.
Clean the operator with a dry lint-free cloth
only.
