Maintenance
WARNING!
NEVER REMOVE OR LOOSEN (1)
OR MORE GUY CABLES WITHOUT
PROVIDING OTHER MEANS OF SUPPORT
TO THE ELEVATOR LEG!
Regularly scheduled maintenance can greatly
increase the life of your equipment and reduce
downtime. A good maintenance program
includes general housekeeping, adequate
periodic lubrication, and periodic inspection.
Remember to check the elevator immediately if
any unusual noise or vibration is detected.
Following is a list of some things you should
check periodically at the given specified
intervals.
1) Check the belt frequently to make certain it is
running in the center of the leg. Check the belt
alignment every hour for the first 10 hours and
daily thereafter. A rubbing belt could quickly cut a
hole in the side of the leg or cause sparks.
2) Check the bucket bolts for tightness after 10,
30, and 100 hours or operation and every 200
hours thereafter.
3) Bearings are greased at the factory and
do not need to be greased before start-up.
Grease all bearings every 800 - 1,000 hours
after start-up. While the unit is running use
only enough grease until you can see the fresh
grease at the seals. If you cannot lubricate
the bearings while the unit is running, do it
immediately upon shut down while the bearing
is still warm. Do not grease a cold bearing.
4) Be certain to maintain the reducer as
specified by the manufacturer. Follow the
manufacturer's recommendations for periodic
oil level inspection and oil changes.

5) Check the head pulley and drive belt after
10, 30, 100, and every 300 hours, or twice
yearly thereafter. Refer to
next page for correct belt tension. The best belt
tension for a V-belt drive is the lowest tension
at which the belts will not slip under the highest
load condition.
6) Oil the motor every 1,000 hours or once
yearly if equipped with oil holes or grease unit
if zerks are available.
7) Check guy cables, turnbuckles, and cable
clips every 3 months for damage or loosening.
If any cable needs to be tightened, use the
procedure given on
i
IMPORTANT NOTE: Any change in the cable
tension may cause the leg to go out of plumb,
resulting in the belt not running straight or even in
structural damage to the leg.
8) Check for deterioration or looseness of
any bolts or fasteners and continued secure
attachment of all ladders.
9) Check for damaged or missing cups.
10) Check the pulley hub bolts and set screws
after the first 8 - 10 hours of operation.
11) Check for worn holes in spouting.
