Preventive Maintenance Schedule

IMPORTANT! The following are MINIMUM maintenance requirements:

Daily (assuming 24-hour-per-day operation during drying season)

• Clean foreign material from the Fan Inlet Guards.
• Sweep off the top exhaust slope where fines have accumulated on outer perforated skins.
• Visually check for uniform grain movement along all perforated panels of the lower outer grain column slope. Pay particular attention to the area directly under the Wet Grain Hopper where excessive amounts of fines and foreign material can accumulate.
• Check the grain supply for chunks of frozen material in cold weather which may wedge a conveyor, causing a Belt burnout, chain breakage, or a Motor overload shutdown.

Semi-Weekly: Shut down for cleaning

• Check inner perforated skin panels for dust and chaff accumulation (especially if grain has excessive foreign material). Sweep down if necessary and remove mate- rial from inside the Dryer.
• Through an open panel, sweep fines and chaff accumulated on top of the Unload Cover, down into the Unload. Check Drag Cover Access Panels, to be sure a proper seal is maintained.
• Replace all Covers and Guards.

Weekly

Inspect the Plumbing Train. Drain the drip-leg on LP-gas model Dryers. Use pipe joint compound on pipe threads when replacing the plug or cap. It may be necessary to clean these each week or more often, as fuel quality in some areas is poor. Check for and correct gas leaks around plumbing fittings, especially on high-pressure Vaporizer lines.
