Martin Sprocket & Gear Bucket Elevator Safety - Manual (Page 12)

Operation
START UP (All Types)
Check to insure elevator is free of foreign materials before connecting power.
Check to insure all guards, covers, safety devices and controls are in place and operating correctly.
Initial start up of elevator should commence with several short jogs gradually lengthening in duration without material.
Check take-up adjustment after 8 hours.Retighten all fasteners. Check and realign sprockets/pulleys as necessary.
Gradually begin feeding material to the elevator. Increase feed rate slowly until reaching design capacity. Empty
elevator. LOCK OUT/TAG OUT ALL POWER. Check for loose fasteners. Check alignment of sprockets/pulleys.
Elevator should be checked for loose fasteners and alignment at least once a month.
OPERATION (Chain Type)
When elevator is new it is common to have an occasional tight chain joint. This will cause some vibration but will eventually
loosen.
If plastic buckets are used in conjunction with metal breaker buckets, it is normal to experience some pulsation.
Characteristics of the material will affect the degree of pulsation. Pulsation is caused by the difference in bucket projection.
Do not intermix old chain and new chain in parallel strands. Always order matched lengths.
Primary to satisfactory elevator operation is uniform material feed rates—not surge loading and excessive boot flooding.
When consulting the factory regarding a specific elevator, refer to the purchase order number, year of manufacture if known,
and equipment number if appropriate.
Regular inspection and maintenance will insure uninterrupted and satisfactory elevator performance.
