Check the oil level and condition in the gearbox. The gearbox should be approximately
half full (16 ounces). Add oil if low. If the oil appears excessively contaminated, change
the oil. Use Exxon-Spartan Synthetic EP 100 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.
Grease the gearbox every two hundred hours or 6 months for maximum life expectancy.
Be sure to use the correct fluid in the gearbox! Check fluid level and
quality daily! Incorrect fluid, inadequate fluid level, or contaminated
fluid will cause gearbox damage!
