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 removed by sharpen-
ing.
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 CATA-
STROPHICALLY AND CAUSE BODILY INJURY OR DEATH.
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR OTH-
ERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY CAUSE
SERIOUS INJURY FROM THROWN BLADES. (SGM-10)
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
(due to running in gravel and/or contact with the
ground),
REPLACE BLADES ON THAT CARRIER IMMEDIATELY.
Failure to replace such
abnormally worn blades may lead to catastrophic failure of the blade and ejection of the bro-
ken part with tremendous force which may cause bodily injury or death!
NOTE: Replace Blades after no more than 1/2" notch wear!
BLADE SHARPENING
Always sharpen both cutting edges of each blade at the same time, the same amount, to maintain balance. Follow
original sharpening pattern as shown. Do not sharpen blade to a razor edge, but leave a 1/32” blunt edge. Do not
sharpen back side of blade. Figure Mnt-R-0303.
When sharpening blades, grind each blade the same amount to maintain balance. 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.
