OPERATING THE CONVEYOR
Since the Conveyor has been previously
operated without material, it may now be
tested under load. It is suggested the fl ow
systems be checked next. Allow only a small
amount of grain to enter the Conveyor. Check
that the material can fl ow through the system,
connections, valves, distributors, etc. Once all
fl ow paths have been checked, the Conveyor
may be loaded to capacity.
CHECK THE CONVEYOR FOR:
A) Electrical current draw on the motor.
A CONVEYOR INSPECTION IS
SUGGESTED AFTER OPERATING
THE FIRST 8 - 10 HOURS.
Inspection
should include:
B) Inspect motor drive pulleys, sprockets, belts,
chains, or torque arm for any looseness.
C) Check for oil leakage or gear reducer
overheating.
D) Check head and tail sprocket hub bolts and
set screws.
