10. Common Problems
From conversation with customers over a period of years, we have complied a list of the ten problems most generally encountered when setting up a new machine.
1. Fans Running Backwards – At least half of the problems with new machines can be traced to backwards rotation of the fans. If it seems insufficient air is the problem, check fan rotation. When viewed from the discharge end, a Left Hand Maxi-cap’s shafts should turn counter clockwise, Right Hand models should run clockwise.
2. Blinded Decks – If there is insufficient air and the fans are running correctly, clean the deck. The deck can be cleaned best by blowing the dirt and chaff out from the top downward, while the gravity separator is running.
3. Dirty Air Filters - The air filters on the side of the machine are designed to screen dirt out of the air before it enters the machine. If they become plugged, the fan cannot pull enough air through them to provide proper separation. The air filters can be cleaned by removing the filters and using compressed air to blow out the dirt. If you must clean filters while the machine is running use an industrial vacuum cleaner and vacuum the dirt from the filter surface.
4.Inadequate Foundations – Although Oliver Maxi-cap Gravities are counterbalanced, they must be attached to a secure foundation. If any vibration can be felt in the floor while the machine is running, the foundation is probably too weak. Weak foundations lower the quality of separation because the foundation absorbs some of the oscillating action intended for separation. Call the factory if you feel that you have an installation problem.
