Blade Sharpening
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL
BLADE DOES NOT CUT GRASSCLEANLY.

WARNING: Use gloves and proper eye protection while
removing, sharpening, and installing blade. Ensure that
safety key and battery pack are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:
• Make sure blade remainsbalanced.
• Sharpen blade at the original cuttingangle.
