Check the oil level and condition in the gearbox. The gearbox should be approximately
half full (28 ounces). Add oil if low. If the oil appears excessively contaminated, change
the oil. Use SAE 80W-90 grade gear oil.
Inspect the entire area around and under the gearbox for any oil leakage. If a leak is dis-
covered, repair it and refill the gearbox before operating the Articulator.
