MAINTENANCE/INSPECTION PROCEDURE 1. Check before starting repairs The following faults can be remedied by cleaning and oil- ing. Check the needed lubrication and the conditions of cleanliness in the unit. Check with the customer to find out how often the unit is used, and then determine that the unit is ready for inspec- tion and maintenance.
MAINTENANCE/INSPECTION PROCEDURE 2. Required Maintenance The recording density of a VCR(VCP) is much higher than that of an audio tape recorder. VCR(VCP) components must be very precise, at tolerances of 1/1000mm, to ensure com- patibility with the other VCRs. If any of these components are worn or dirty, the symptoms will be the same as if the part is defective.
MAINTENANCE/INSPECTION PROCEDURE 5-2) Greasing (1) Greasing guidelines Apply grease, with a cleaning patch. Do not use exces- sive grease. It may come into contact with the tape transport or drive system. Wipe excessive grease and clean with cleaning patch wetted in Isopropyl Alcohol. NOTE:Greasing Points 1) Loading Path Inside &...
