10.4 Weighfeeder storage recommendations
If a weighfeeder will be stored for a period of three months or more, follow the guidelines below:
10.4.1 Load cell care
The load cell shipping bolts should be installed whenever the feeder is moved as an extra safety
measure during the storage period. Do not forget to remove the shipping bolts upon re-
installation.
10.4.2 Gear reducer/Gear motor
Uncouple the gear reducer from the feeder drive shaft and the motor and grease all shaft
surfaces liberally with an appropriate lubricant to help with reassembly.
In addition, fill the gear reducer with an appropriate gear oil to prevent oxidation. When the
equipment is re-installed, completely drain this gear oil and then refill the reducer to the
appropriate level.
10.4.3 Electrical
To prevent oxidation, place a desiccant or moisture removal material in all electrical junction
boxes and component cabinets. This includes the load cell junction box, the integrator cabinet,
and the motor speed controller enclosure (if present).
10.4.4 Lubrication
Grease all greasable points.
10.4.5 Belt care
Reduce belt tension to a minimum to prevent belt damage and re-adjust belt tension at re-
installation.
Note
Do NOT store the weighfeeder in direct sunlight, as this will cause premature breakdown of
the belt.
