1-5-3 Lubrication of Tape Mechanism
The tape transport mechanism is properly lubricated
at the factory. In normal use cycles, and with average
environmental conditions, additional lubrication
should not be required during the first year of
operation.
Depending on the frequency of use and environmen-
tal conditions, periodic lubrication may be required.
When lubricating, first remove the old lubricant, then
sparingly apply new lubricant. Excessive lubricant is
transferred to other assemblies, malfunction will
result.
