4-5-3 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
environmental 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.
Use grease on the following parts every 1,000
hours. (See exploded view for location) :
1. Between base pole assembly (L, R) and main
base
2. Gear Loading L, R
3. Slide Main
4. Lever Shift
5. Gear Master

2. Shaft Reel Disk L, R
3. Shaft Gear Relay S, T
4. Shaft Idler
