TM 5-3895-374-24-2OperationLubricate all bearings and drives per service instructions. Gear reducers are normally shipped without lubricant. Refer toservice instructions for lubrication.Check conveyor to insure all tools and foreign materials have been removed.Check conveyor to insure all covers, guards, safety devices or controls, and any interlock to other equipment is installedand operating properly.In start-up of the conveyor, operate several hours empty as a break in period. Observe for bearing heat up, unusualnoises or drive misalignment. Should any of these occur, check the following and take necessary corrective steps. (non-lubricated hanger bearings may cause some noise)1) When anti-friction bearings are used, check for proper lubrication. Insufficient or excess lubricant will cause highoperating temperatures.2) Misalignment of trough ends, screws, hangers and trough end can require excessive maintenance and cause poorlife expectancy.3) Check assembly and mounting bolts; tighten if necessary.After the conveyor has been run per the above instructions, stop the conveyor. Lock out all power, and check discharge toinsure it is clear and material flow through the discharge will not be impeded in any way.Restart the conveyor and gradually begin to feed material. The feed rate should be gradually increased until the designcapacity is reached.Do not overload conveyor. Do not exceed conveyor speed, capacity, material density, or rate of flow for whichthe conveyor and drive were designed.Cut off feed and allow the conveyor to empty. Lock out all power supply. Check all bolts and all alignments. Realign asnecessary and tighten all bolts.If the conveyor is to be inoperative for a prolonged period of time, operate conveyor until cleared of all material. This isparticularly important when the material conveyed tends to harden or become more viscous, or sticky if allowed to standfor a period of time.It may be necessary to recenter hanger bearings after running material in conveyor.Check motor amperage frequently.It Is extremely Important the following precautions be followed to prevent personal or property damage:1 ) Only persons properly trained and familiar with screw conveyors be permitted to operate or maintain the unit.2) LOCK OFF ALL POWER prior to any inspection or maintenance.3) Periodically run the conveyor empty for a few minutes to check for excessive vibration, loose fasteners, security ofcovers and guards, noise, and bearing and drive temperature.4) ALWAYS operate the conveyor with covers, guards, safety labels in place.5) NEVER walk on or cross conveyor covers, guards, or grating.6) DO NOT place hands, feet, or clothing in conveyor openings.7) DO NOT poke or prod the conveyor or material in the conveyor.8) ALWAYS practice good housekeeping and keep a clear view of the conveyor loading, discharges, and all safetydevices.page 3 - 750
