Cleaning The Silicone Covered Rollers; Preventive Maintenance; Auto-Grip Shafts - SEAL 65 EL Handbuch

6.1 Cleaning the silicone covered rollers

The rollers must be cleaned regularly to prevent a build-up of residue. This may eventually damage
the rollers.
Use a damp lint-free cloth to remove dust and other dirt.
Difficult stains can be removed with the aid of isopropyl alcohol (IPA) and a clean lint-free cloth.
Do not pour isopropyl alcohol directly on the machine.
WARNING:
ISOPROPYL ALCOHOL IS VERY FLAMMABLE! THE FLASH POINT OF IPA IS
11°C (51.8°F). THE SELF-IGNITION TEMPERATURE IS 400°C (752°F).

6.2 Preventive maintenance

SEAL® machines are designed so they need little (preventive) maintenance in addition to the
cleaning.
The following checks have to be performed:
•
Auto-grip shafts with blocking cords.

6.2.1 Auto-grip shafts

Check the auto-grip mechanism on each shaft.
•
The distance (d) between the rubber cord and flat edge should be 8 ± 2.5 mm minimum.

•
Put the end of the cord back underneath the clamp (2).
•
Secure it by tightening the screw (1).
