What maintenance needs to be performed on the belt sander motor.
Baldor recommends greasing the motor bearings about every two years with either Chevron SRI#2 or Exxon PolyRex-EM or equivilent grease. If you work in a dusty and wet environment or the sander is being used more than 12 hours a day, then grease the motor bearings once a year.
