10.2 General maintenance
The equipment should be cleaned periodically and any excess accumulation of product should
be removed to minimize potential damage to the mechanical components and scale accuracy.
Abrasions, cuts, or ragged edges on the belt will create performance problems. Replace the belt
if it becomes ragged or torn.
10.3 Lubrication
All head and tail pulley bearings are pre-greased at the factory. These bearings should be field
greased periodically. Lubrication frequency may vary; dry, dusty applications may warrant
weekly greasing, while less harsh applications may need greasing only once or twice a year. Do
not exceed 10,000 hours of operation between re-greasing.
If there is a gear reducer supplied with your weighfeeder, it has an initial break-in period. After
the first 250 hours of operation, the gear box(es) should be drained and refilled to the proper
level(s). Subsequent oil changes should be done every 2500 hours. See the gear reducer
manual provided for further details.
If there is a gear motor (motor and reducer all in one housing) supplied with your unit, it is
permanently lubricated. No lubrication is necessary.
