Maintenance
WARNING!
DISCONNECT AND LOCK-OUT ALL
ELECTRICAL POWER BEFORE DOING
MAINTENANCE.
Regularly scheduled maintenance can greatly
increase the life of the equipment and reduce
downtime. A good maintenance program
includes general housekeeping, adequate
regular lubrication, chain tension adjustment,
and periodic inspection. Remember to check
the Drag Conveyor immediately if any unusual
noise or vibration is observed.
Following is a list of some things you
should check regularly at the given
specifi ed intervals.
1) Bearings are greased at the factory and
do not need to be greased before start-up.
Grease all bearings every 800 - 1000 hours
after start-up. When the unit is running use
only enough grease until you can see the fresh
grease at the seals. If you cannot lubricate
the bearings when the unit is running, do it
immediately after shut down when the bearing
is still warm. Do not grease a cold bearing.
2) Make certain to maintain the reducer as
specifi ed by the manufacturer. Follow the
manufacturer's recommendations for periodic
oil level inspection and oil changes.
3) Check the Drag Conveyor chain frequently
for "buckling" or "kinking" while under load.
Adjust the chain tension as required. Once
the maximum take-up position is reached it
will be necessary to remove some chain links.
Establish a schedule for checking the chain
tension. MFS/YORK/STORMOR recommends
checking the tension at least once a quarter
following the initial break-in period.

4) Oil motor every 1000 hours or once yearly if
equipped with oil holes or grease unit if zerks
are available.
5) Check the V-belt drive after 10, 30, 100, and
every 300 hours, or twice yearly thereafter.
Refer to the previous page for correct belt
tension. The best tension for a V-belt drive is
the lowest tension at which the belts will not
slip under the highest load condition.
6) Check for deterioration or looseness of any
bolts or fasteners.
7) Check for worn, damaged, or missing
UHMW paddles.
8) Check the sprocket hub bolts and set screws
after 8 - 10 hours of operation and on regular
intervals thereafter.
9) Check that all guards are properly located
and installed.
