MANUAL INSERT
PRODUCT: 5” CHIPPERS
MODEL: 74520 & 74554
SUBJECT: PTO LOFA CONTROL REVISION & TORQUE BOLT SPECIFICATIONS
The information for programming the LOFA control (page #16) is incomplete in the manual #12666, revision 11/01. The
programming information for engine models is correct, however the information for the PTO models is not. Refer to the table
below for all correct LOFA control settings.
Also, the chipper blade torque specification was omitted from the Service and Maintenance section of the owners manual
(page #19). When replacing chipper blades (P/N 70739), torque the retaining bolts (P/N 15565) to 20 ft/lbs.
