ASSEMBLY INSTRUCTIONS
STEP 9. Install the knife using 2) ½” x 2” GR. 8 bolts and ½” lock nuts to the L.H. and R.H. knife mounts.
STEP 10. Tighten all bolts to recommended torques from table on page 8 of this manual unless the torque
is specified.
Note: Do not over tighten the spindle bolt and castle nut. Torque the spindle bolt to 13-15 ft. lbs. or until
the hub/blade assembly has a slight drag when turned by hand. Back off the nut one slot position on the
castle nut to line up the cotter pin hole. Secure the nut with the 1/8” x 1” cotter pin provided.
Recheck the torque on these bolts after 10 hours of operation and then every 50 hours after that. Do a
routine inspection of the opener at this time for best performance and less down time.
