4. Important notes and information
4.1 Cleaning and maintenance
The maintenance periods given here are based on a d aily use of approx. 4 hours. If the system is in operation longer,
you will need to maintenance it more frequently.
For example:
If used for four hours a day for DIN A4 format with two cuts, this adds up to approx. 60,000 machine cycles (mod.
6611) and approx. 120,000 cutting cycles. Over a period of one month (20 working days), this is equal to over two
million cutting cycles.
The following maintenance plan is appropriate for this amount of use:
Every month: replace or turn around the blades (cross cutter and edge cutter).
Approx. every 4 months: replace the rear cutter guide bar.
Approx. every 12 months (approx. 20 millionen cuts): replace motors.
To ensure trouble-free operation, replace parts subjected to high loads before they fail!
We recommend that the operator perform the following
maintenance work after every 500,000 cuts.
1. Clean all areas accessible from outside with a vacuum
cleaner. Do not use compressed air.
2. Apply two drops of oil to each edge cutter unit and to the
centre cutter 6875 (if present) .
The following maintenance work should be performed by a service
technician every 2 million cutting cycles:
If necessary, replace or turn around the edge and cross cutter blades
(see Service Instructions). Clean the sliding surfaces of the cross blade,
inspect for wear and grease lightly (if necessary, replace the rear cutter
guide bar). Apply one drop of oil to the upper pivot pins
of the
connecting rod on the cross cutter drive. Wipe away any excess oil
which drips onto the connecting rod.
The following maintenance work should be performed by a service
technician every 3 months (every 5-6 million cutting cycles):
1. All maintenance work peformed by the operator.
2. Use a vacuum cleaner to clean the machine inside and outside. Do
not use compressed air.
3. Clean both encoder disks and the scanning heads on the cross
cutter and tractor (see Service Instructions).
4. Inspect the flat belts and make sure they are still centered.
Remove any dirt which may have accumulated on the running
surfaces.
5. Begin service routine 10 and adjust the machine automatically.
If service routine 10 is finished, the display chan ges into service no
9 level 3 and shows the DA values. The DA-values should not be
over 200. (for further information see pt. 4.4, S.52). Press the
"Prog"-button two times and start service routine n o 000 to return to
the program.
6. Check that the tractors and edge cutter units stop correctly. Adjust
them if necessary.
7. Grease hexagonal shafts and both shafts .
