Blade Care & Sharpening

Sharp blades provide a clean cut and reduce strain on the engine.

Disconnect spark plug wire for safety.
Raise deck to highest position and block securely.
Remove blade bolt (may require breaker bar; note rotation direction for reinstallation).
Sharpen blade with a file or grinder to maintain original cutting angle. Balance blade using a balancer.
Reinstall blade with bolt tightened to 70-90 ft-lbs. Torque properly.
Check blade condition regularly for excessive wear, cracks, or damage. Replace if damaged.

WARNING! Always wear heavy gloves when handling blades.

Storage & Winterization

Add fuel stabilizer to gas tank and run engine for 5 minutes to circulate.
Change engine oil and filter at end of season.
Clean mower thoroughly, especially under the deck.
Remove battery, clean terminals, and store in a cool, dry place on a trickle charger.
Store in a clean, dry place, preferably covered.

CAUTION! Do not store with fuel in tank for more than 30 days without stabilizer.
