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.
WARNING Use only original equipment blades on this cutter. They are made of special heat-treated
alloy steel. WILL-FIT BLADES MAY NOT MEET SPECIFICATIONS AND MAY FAIL
CATASTROPHICALLY AND CAUSE BODILY INJURY OR DEATH.
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as
shown in FIGURE 11. Always sharpen blades by grinding. DO NOT heat and pound out 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.
WARNING 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.

DANGER Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge
at the lower bend more than a 1/2" DEEP (FIGURE 12) (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!
FOLLOW ORIGINAL
PATTERN
DANGER!
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.
