MAINTENANCE
BLADE SERVICING
Inspect blades before each use to determine that they are properly installed and in good condition. Replace
any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out
when sharpening.
Use only original equipment blades on this cutter. They are made of special heat-treated
alloy steel. Substitute blades may not meet specifications and may fail in a hazardous
manner that could cause injury.
Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR
WELD ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE
BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM
THROWN BLADES.

•
Manually wiggle the blade carriers to check for any looseness.

Recheck torque every 50 hours.
Operating with loose blade hardware will damage the blade holder and blades. Whenever
the blades have been removed or replaced, the hardware must be retightened after the first
eight hours of operation. On new units check blade hardware and the blade nut torque after
first 8 hours.
Operating with loose blade holder will damage the blade holder and output shaft, two initial
tightenings are required. Retighten after one hour and again after the day of operation. In
severe cutting conditions or commercial use, a daily inspection is required.
To help prevent structural damage caused by loose hardware, tighten gear case hardware
as specified. Check torque after first 8 hours of use and every 50 hours thereafter.
