9.5 FURTHER MAINTENANCE INSTRUCTIONS.
- When the ST2520 is in open position:
- always check the inside of the housing / frame for any dust.
- always check the nuts of the frictions left and right and motor support.
(see fig. 21 – 22 page 21)
- When the table has the counter system, check the sprockets for dirt or
splicing tape remains. Remove dirt with a dental wood stick ,
cleaning solvent and cotton tissue. ( do not use metal tools)
- Also check the guide rollers and clean them regular.
- Keep the film plates clean.
Please handle film plates with care otherwise they can bend.
- Film plate alignment: in cases a none factory installed film plate is put on
the ST2520, there is a possibility you have to re-align the friction base.
In fig. 13 page 21 you see the 3 x 2 nuts to align the friction base.
