Mechanical Equipment

Shutdown for less than 3 months.

Each month, drain water condensate from the lowest point of the Geareduc- er and its oil system. Check oil level and add oil if necessary. Operate Geareducer briefly to recoat all interior surfaces with oil. At start-up, drain water condensate and check oil level. Add oil if necessary.
