7. If cutter is being returned to service from storage, evenly tighten six lock nuts (A) on slip clutch to apply spring load to clutch disks.

IMPORTANT: Slip clutch components must be free to rotate when necessary. Clutch disks will seize if left unused for a period of time, especially in humid or damp conditions. Linings may bond to metal parts causing slip clutch to be ineffective, resulting in machine damage.

8. If cutter has not been used for a while, free slip clutch disks and adjust spring load. (See Freeing Slip Clutch procedure in AS REQUIRED in Lubrication and Maintenance section.)
