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.
Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at
the lower b end more than a 1/2” DEEP (due to running in gravel and/or the ground),
REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to replace such
abnormally worn blades may lead to catastrophic failure of the blade and ejection of the
broken part with tremendous force which may cause bodily injury or death.
NOTE: Replace Blades in pairs after no more than 1/2” notch wear!
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen blade to
a razor edge. Do not sharpen blade to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of
blade.
IMPORTANT: When sharpening blades, grind each blade the same amount to maintain balance. The
difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause excessive vibration
which can damage gear box bearings. Vibration may also cause structural cracks in cutter housing.
Never work under equipment supported by a hydraulic device because it may drop if the
control is actuated (even with the engine stopped) or in the event of hose failure, etc. Always
use a secure support for equipment which must be serviced while in the raised position.
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY
CAUSE SERIOUS INJURY FROM THROWN BLADES.
