9.0 MAINTENANCE INSTRUCTIONS.
9.1 PREFACE.
The Steenbeck ST2520 film rewinder / film inspection table is manufactured and
tested with the greatest care possible. That is why it only requires a minimum of
maintenance to stay in good working order.
This doesn’t mean that the ST2520 doesn’t need maintenance at all.
It needs from time to time some maintenance and we would like to draw your
attention to some details you will find to be of importance.
The main part that needs attention are the two frictions.
These are special frictions with switchable clutches.
When winding forward / to the right, the left friction is a real friction with an adjustable
tension. The clutch of the right frictions is engaged (you hear a click) and becomes a
1 : 1 axle with maximum motor torque.
When you wind reverse / to the left, the system works visa versa.
For adjusting the frictions, see section 9.3.
One of the reason we installed a time elapsed counter (see fig. 4) is to read the hours
the ST2520 was in use.
We strongly advise to dismantle the friction core, clean the friction ring / core and
apply special grease on the friction ring every 150 hours.
For this maintenance, see section 9.4.
CAUTION:
Always make sure to disconnect the mains cable before opening the ST2520
housing. Take the film of the film plates.
In case of running test, just take a small diameter roll of 16mm film when possible.
(approx. max. of 300 meter)
BE CAREFULL:
While opening, take care that the rear roller castors are locked. (fig. 6)
Lift the table top (where the motor and frictions are mounted) slowly.
You can fix the table top by a mounting rod left side frame in the upright
position and insert the mounting rod properly into deck plate.
All works inside the housing must be carried out by skilled and trained
staff only.
9.2 TOOLS
For first line maintenance you only needs two pieces of tools (see fig.14 page 18)
delivered with the ST25250:
- hexagon 2,5 mm for friction ring maintenance.
- wrench 8 mm for friction ring maintenance and checking bolts / nuts.
