5. Make sure maintenance personnel look over the conveyor belt at least weekly and check on the following:
Belt is tracking properly and is not slipping on drive pulley.
Pulleys, rollers, deck, etc. are free from foreign material that could fall in or stick to the belt
and cause damage.
Belt is not being frayed or cut by siderails, chutes, hoppers, etc.
That belt lacing is not being damaged and belt connector pin is staying in the lacing.
MOTORS
1. CLEANING - All motors should be kept free of dirt and grease accumulations. Open motors should be
periodically vacuumed to remove dust and dirt from the windings.
2. VENTILATION - For best results motors should be operated in an area where adequate ventilation is
available.
3. TEMPERATURE - Most of todays smooth body T.E.N.V. and T.E.F.C. Motors run hot to the touch. As long
as maximum ambient temperatures are not exceeded, and more importantly, ampere draw is within the
allowable range, there should be no need to worry. (Both of these limits are found on the motor nameplate.)
4. LUBRICATION - Most electric motors are lubricated for life and under normal conditions require no more
lubrication. Under severe conditions where additional lubrication is required, use the following chart
as a guide.
