BLADE SHARPENING

 

 

 

KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL BLADE DOES

 

 

 

NOT CUT GRASS CLEANLY OR MULCH PROPERLY.

 

 

 

USE PROPER EYE PROTECTION WHILE REMOVING, SHARPENING, AND

 

 

 

INSTALLING BLADE. ENSURE THAT SAFETY KEY IS REMOVED.

 

 

 

Sharpening the blade twice during a mowing season is usually sufficient under normal

 

 

 

circumstances. Sand causes the blade to dull quickly. If your lawn has sandy soil, more

 

 

 

frequent sharpening may be required.

 

 

 

REPLACE BENT OR DAMAGED BLADE IMMEDIATELY.

 

 

 

WHEN SHARPENING THE BLADE:

 

 

 

1.

Make sure blade remains balanced.

 

 

 

2.

Sharpen blade at the original cutting angle.
