Maintenance
Troubleshooting
For corrections requiring repair or replacement or compo-
nents, refer to the appropriate section for your specific
model.
Cleaning
The outside surface of the load should be wiped free of
dust and dirt when necessary. The principal maintenance
required by the operator will be to periodically wipe off
the accumulated dust and lint from the radiator fins. Ex-
cessive collection of dust and lint on the cooling fins will
interfere with the efficient dissipation of heat. If the tef-
lon insulator or metallic contact surfaces of the connector
should become dirty, wipe them off with a soft cloth. Use
a contact cleaner that is self-drying and leaves no residue
on the inaccessible internal parts.
