MAINTENANCE
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 (if applicable) around
the holes.
3.
Lube threads with anti-seize. Install bolts through knife and disk from bottom side of disk/blade bar.
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 800 LUBRICATED FT. LBS.
REPLACEMENT OF ROTARY DISK/BLADE BAR
Failure to follow the following warnings and instructions may result in serious injury or
damage to the equipment or property!
1.
The bolts that attach the disk to the spindle must be grade 8. These 5/8 inch bolts are to be torqued to
204 dry or 184 ft. lbs lubricated with Loctite 271.
2.
A thread locking agent may be applied to threads of all mounting bolts before they are installed.
3.
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.
4.
Inspect the disk mounting bolts daily when checking tightness of knife 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.
5.
If a knife mounting bolt is loose, the self locking nut must be replaced as a safety precaution. Lubricate
threads with anti-seize. Install bolts through knife and disk/blade bar from bottom side. Install self
locking nuts and torque them to 800 ft. lbs.
