Martin Sprocket & Gear Drag Conveyor Safety - Manual (Page 10)

Before any maintenance or inspection is performed, refer to ANSI Standard ANSI Z244.1 for minimum
safety requirements covering LOCK OUT/TAG OUT ALL POWER or energy sources for personal safety.
Practice good housekeeping. Keep the area around the conveyor and drive clean and free of
obstacles to provide any 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 or shorten conveyor chain section, proceed as follows:
1.) Locate the cotter pin section of chain and rotate the chain until it is on the top ( LOCK
OUT/TAG OUT ALL POWER ).
2.) Loosen take-up fully and remove cotter pin and remove desired length.
3.) To reassemble, follow the above steps in reverse order.
Replacement parts can be identified from a copy of the original packing list, invoice or drawing.
Periodic inspections should be made of the following:
1.) Trough. Check for wear and alignment. Tighten all bolts.
2.) Shafts. Check for wear.
3.) Flights. Check edges for wear or damage.
4.) Bolts and nuts. Check all for wear and tightness.
5.) Seals. Check for leakage, adjustment and wear.
6.) Guards. Check for oil level (if applicable). Check nuts and bolts for tightness.
7.) Bearings. Check for lubrication.
8.) Sprockets. Check for wear and alignment.
9.) Chain. Check for worn pins and damaged side bar.
10.) Take-up. If take-up fully adjusted, a link of chain will need to be removed.
Extended Shutdown / Storage

should be performed:
1) Insure all foreign material is removed from the conveyor and surface coatings are in good
order.
2) All bearings and drives are lubricated and protected per manufacturer’s instructions.
3) The conveyor is protected from weather, moisture and extreme temperatures. Do not use
plastic or other coverings which promote condensation under the covering.
4) All exposed metal surfaces are coated with a rust preventative oil that is applied per
instructions.
5) Prior to start-up, installation and operation instructions contained in this manual must be
