Maintenance
This chapter contains operator maintenance instructions,
troubleshooting, and parts information.
Troubleshooting
Cleaning The principle maintenance required by the operator will
be the cleaning of the radiator fins. Periodically wipe
away the accumulated dust and lint. If the insulator or
metallic contact surfaces of the connector should become
dirty or grimy, wipe them off with a soft cloth and use a
contact cleaner that is self drying and leaves no residue
to clean the inaccessible internal parts.
