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.
• Sharpen cutting edges on both ends of blade, removing
equal amounts of material from bothends.
