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.
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 the mower.
Use only original equipment blades on this mower. 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.
When changing Blades always replace the Blade Bolt & Blade Nut at the same time. Reuse of Blade Bolts or Nuts could fail in a hazardous manner that could cause injury.
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in Figure 4. 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.
Avoid personal injury. Always block the mower up to prevent if from falling when the blades and/ or carrier are being serviced.
Avoid Personal injury. Always wear safety glasses and face protection when grinding blades.
Do Not heat, weld, or hard surface blades as this can alter material strength causing blades to fail in a hazardous manner that could cause injury.
