Introduction

Thank you for selecting the Martin Yale Model 959AF Air-Feed AutoFolder. All components have been thoroughly inspected and
performance tested to provide you with the best folder value in its class. Before each machine is packed for shipment, it must
pass a critical performance test, including folding, scoring, and perforating. This folder can execute Half, Double Half, Zee,
French, Baronial, and custom folds within its paper size capacity, as well as Letter Folds (up to 17” paper).  The machine can also
score, slit, and perforate separately, or while folding. 

Please review this publication in its entirety before attempting to operate your folder. Thorough understanding of this information
will help eliminate most operator-associated errors and ensure years of trouble-free performance.

WARNING!  Never connect power to the machine until you are ready to set up and operate the folder. This
machine contains moving parts. During setup, operation, and maintenance keep hands, hair, loose clothing, and
jewelry away from all moving parts. Serious bodily injury could result. Service, or disassembly of side covers
should only be attempted with the power disconnected and locked out.  The AC outlet for this machine must be
near by and not blocked.
