SERVICE TIP

Operation

Lubricate all bearings and drives per service instructions. Gear reducers are normally shipped without lubricant. Refer to service instructions for lubrication.

In start-up of the conveyor, operate several hours empty as a break-in period. Observe for bearing heat up, unusual noises 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 high operating temperatures. 
   
   
2. Misalignment of trough ends, screws, hangers and trough end can cause excessive maintenance and poor life expectancy.
   
   
3. Check assembly and mounting bolts; tighten if necessary.

Do not overload conveyor. Do not exceed conveyor speed, capacity, material density, or rate of flow for which the conveyor and drive were designed.

If the conveyor is to be inoperative for a prolonged period of time, operate conveyor until cleared of all material. This is particularly important, when the material conveyed tends to harden or become more viscous, or sticky, if allowed to stand for a period of time.

It may be necessary to re-center hanger bearings after running material in conveyor.

Maintenance

Practice good housekeeping. Keep the area around the conveyor and drive clean and free of obstacles to provide easy access and to avoid interference with the function of the conveyor and drive.

Establish routine periodic inspections of the entire conveyor to insure continuous maximum operating performance.

To replace conveyor screw section, proceed as follows:

1. Removal of a section, or sections, usually must proceed from the end opposite the drive. Make sure drive and electrical power are disconnected before starting to disassemble.
   
   
2. Remove the trough end, sections of screws, couplings shafts, and hangers until all sections have been removed, or until the damaged or worn section is reached and removed.
   
   
3. To reassemble, follow the above steps in reverse order.
   
   
4. Quick-removable conveyor screws can be removed at intermediate locations without first removing adjacent sections.

Replacement parts can be identified from a copy of the original packing list or invoice.

The coupling bolt contains a lock nut that may become damaged when removed. It is recommended practice to replace lock nuts rather than re-use them when changing conveyor screw sections.
