7. MAINTENANCE
The Mini Servo Roll Feed needs very little maintenance to keep the system operating at its optimum performance.
• This precision equipment must be kept as clean as possible. This is especially important if large amounts of
air suspended oil mists in combination with “dirty metals” are used. The resulting abrasive dust can attach itself to the
feed rolls and other surfaces, leading to premature wear on many parts.
• The roll release system requires a clean, dry air supply.
• Some bearings used on the feeder are fully sealed and maintenance-free roller ball bearings. The exceptions
are provided with standard “zerk” type grease fittings. They should be lubricated with a good grade of high pressure
bearing grease. The frequency of lubrication will depend on the overall usage of the system. A small “shot” once a
day is a good starting point. The cluster gear set should be coated with a small amount of open gear grease.
• The main drive belt should be checked periodically for tightness. It can be adjusted by loosening the three
fasteners on the motor adjuster plate, applying downward pressure on the plate, and retightening. ERRATIC MOTOR
BEHAVIOR WILL BE EXPERIENCED IF THE DRIVE BELT IS LOOSE!
• All fasteners should be checked for tightness at regular intervals. The electrical system also requires very little
maintenance. Keep the enclosure clean and replace any burned indicator bulbs. Do not expose the electrical enclosure
to constant high temperatures. Possible system failure could result.
• The Feeder’s electrical enclosure door is sealed to prevent oil and contaminants from entering inside.
However, small gaps can be found around some sealing surfaces and faceplates. It is a good idea, therefore, to keep the
console free of stamping oils and fluids, which could "seep into" the enclosure. Most often these oils are carried by the
operator’s hands or by air mist lubrication etc.
• All of the above guidelines should be added to your existing pressroom Preventive Maintenance
(PM) Program.
