10 MOST FREQUENT PROBLEMS
From conversations with processors over a period of years, we have compiled a list
of the ten problems most generally encountered when setting up a new machine. We
list these problems below along with some suggested solutions.
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 that you have a problem with
insufficient air, we suggest you check this, as silly as it seems. When viewed from
the side where the motor is located, the fans and shafts should run counter-
clockwise.
2.
Blinded decks. If you think you have insufficient air and the fans are running
correctly, remove the deck and clean it. The deck can be cleaned best by blowing
the dirt and chaff out from the top down.
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 fans cannot pull enough air through them to provide a proper separation.
They can be cleaned by removing them from the machine and gently tapping
them on the floor. A more effective cleaning may be obtained by removing the
filters and using compressed air to blow the dirt out.
4.
Inadequate foundations. Although Oliver Stoners are counterbalanced, they must
be attached to a secure foundation. A six-inch concrete slab is best but is not
essential. Many processors run Oliver Stoners on wooden floors with no problems.
If you can feel any vibration in the floor while the machine is running, you probably
have too weak a foundation. Weak foundations lower the quality of separation,
because the foundation absorbs some of the oscillating action intended for
separation.
5.
Operating at too much capacity. Often merely lowering the operating capacity
slightly will greatly improve the separation. Capacity is usually dependent on the
