motors may have grease fittings and grease outlet plugs. Use the
lubricating instructions provided on the motor nameplate or in
accompanying documents. If no instructions are available, then until

a) use Shell Dolium R or Chevron SRI grease, and
b) once per year use the following instructions:
1. Be sure the electric power to the unit is OFF, locked out, and
tagged out.
2. Clean all grease fittings or plugs to remove any paint, dirt, or dust.
3. Clean any dirt or old grease from around a grease outlet plug.
4. Remove and retain the grease outlet plug. Do not allow it to
become dirty.
