4.8. General Maintenance
The charger requires a minimum of maintenance. Connections and terminals should be kept clean and
tight. The charger should be periodically cleaned with an air hose to prevent any excessive dirt build up
on components. Care should be taken not to bump or move any adjustments during cleaning. Make sure
that both the AC lines and the battery are disconnected before cleaning. The frequency of this type of
maintenance depends on the environment in which this unit is installed. If any cabinet sheet metal panels
are removed for cleaning, be certain they are properly reinstalled upon completion.
