BLADE SHARPENING
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL BLADE DOES NOT CUT GRASS CLEANLY.
USE PROPER EYE PROTECTION WHILE REMOVING, SHARPENING, AND INSTALLING BLADE. ENSURE THAT SAFETY KEY and battery pack 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.
3. Sharpen cutting edges on both ends of blade, removing equal amounts of material from both ends.
TO SHARPEN BLADE IN A VISE: (Figure Z)
1. Be sure the bail handle is released, the blade has stopped and safety key and battery pack removed before removing the blade.
2. Remove blade from mower. See instructions for removing and installing blade.
3. Secure blade (35) in a vise (38).
4. Wear proper eye protection and gloves and be careful not to cut yourself.
5. Carefully file the cutting edges of the blade with a fine tooth file (39) or sharpening stone, maintaining the angle of the original cutting edge.
6. Check balance of blade. See instructions for blade balancing.
7. Replace blade on mower and tighten securely.
