THANK YOU FOR PURCHASING AN STERLING BP2400 SERIES GRANULATOR.

READ THIS MANUAL to learn how to operate and service your granulator safely. It covers the family of granulators called the BP2400. This series of Sterling Granulators is designed for the big jobs in reclamation of large blow-molded and thin walled, injection molded plastic parts as well as film.

This revision of the manual covers the improvements made since the introduction of the BP2400 Series Machines in 1993.

NOTE: This manual covers light maintenance only. No further maintenance should be performed without first contacting the Sterling Service Department at the mailing address and phone number shown on page 2.
