ROTARY KNIFE REPLACEMENT
1. Be sure you have a complete matching set of new knives for replacement.
2. Remove knives and inspect holes for damage. Also watch for cracks in the disk around the holes.
3. Lube threads with anti-seize, motor oil or grease. Install bolts through knife and disk from bottom side of
disk. Install new self-locking nuts and torque them to 800 ft. lbs.
4. The knives should swing freely to absorb shocks from impact when striking objects.
WHEN CUTTING HEAVY BRUSH, KNIFE BOLTS SHOULD BE INSPECTED HOURLY AND
RETORQUED TO 1070 DRY OR 800 OILED FT./LBS.
REPLACEMENT OF ROTARY DISK
Failure to follow the following warnings and instructions may result in serious injury or
damage to the equipment or property!
The bolts that attach the knife mo unting disk to th e spindle must be grade 8. These 5/8 inch bolts are to be
torqued according to the chart in this section.
A thread locking agent may be applied to threads of all mounting bolts before they are installed.
Disks must be inspected daily for hairline cracks between spindle mounting bolts or around the knife
mounting bolts. These cracks indicate metal fatigue caused by severe abuse. If cracks are present. the
disk must be replaced.
Inspect the disk mounting bolts daily when checking tightness of blade mounting bolts. If a disk mounting bolt is
loose, it must be removed, threads cleaned, fresh thread locking agent applied, and tightened to proper torque
value.
If a knife mounting bolt is loose, the self locking nut must be replaced as a safety precaution. Lubricate threads
with anti-seize, grease or motor oil. Place bo lts through knife and disk from bottom side of disk. Install self
locking nuts and torque them to 800 ft. lbs.
