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 con-
tact 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 inac-
cessible internal parts.
