Riblet Service Bulletins The Riblet Tramway Company issues Service Bulletins from time to time, to assist Riblet customers in the safe and efficient operation of their Riblet Chairlifts and other products. Riblet's first Service Bulletin, at the time called a "service letter", was issued in 1963. In October of 1979, the National Ski Areas Association distributed a recommended format for the preparation and issuance of service bulletins. Since October of 1979, Riblet Service Bulletins have followed that format, with one exception: Riblet Service Bulletins are issued by the company, not by an individual, and as such they are generally not signed by an individual. Riblet Service Bulletins are dated with the issuance date, and are identified by the heading "Service Bulletin #YYYY-NNN", where YYYY is the year of issue and NNN is a sequential number, which started with Service Bulletin #1963-1. Following the issuance date, heading, and Service Bulletin number are: Applicability: This is the Riblet product to which the Service Bulletin applies. Subject: The subject of the Service Bulletin, which may be a specific part, procedure, etc. Compliance: There are three classifications of required compliance:
As an aid to help identify the action required, Service Bulletins, when originally issued, and their mailing envelopes are stamped with the compliance classification, in Red, Orange, or Green, respectively. Where necessary, Service Bulletins are sent by Certified Mail. Service Bulletins, when copied, faxed or e-mailed, or when sent on request, are not identified by the colored stamp. A few Service Bulletins are Applicable to "All Riblet and other chairlifts using....", or similar wording. Most, however, are applicable only to "...Riblet chairlifts..." A Riblet Chairlift is a chairlift that was originally engineered and furnished by the Riblet Tramway Company, is in the location where it was originally installed, and which has not been modified, relocated, or altered by others without the authorization and written approval of the Riblet Tramway Company. There are many chairlifts which, though they may consist entirely or partially of components originally supplied by the Riblet Tramway Company, are not "Riblet" chairlifts. Such chairlifts may have been relocated, with engineering services furnished by others, they may be chairlifts originally designed and furnished by Riblet but modified or altered by others (with or without engineering services furnished by others), or they may be chairlifts designed by others using collections of components including some components originally sold by Riblet. The Riblet Tramway Company has no way of knowing whether Riblet Service Bulletins apply to such lifts. Indeed, we may not know of the existence of such lifts. Notes:
