Engine Care

Proper engine maintenance is critical.

Oil Change: Run engine to warm oil. Drain via drain plug into pan. Refill with 2 quarts of SAE 30 or 10W-30.
Air Filter: Replace paper element every 50 hours; clean foam pre-filter if equipped.
Spark Plug: Gap at 0.030 inches; replace annually or every 100 hours.
Fuel System: Use fuel stabilizer if storing over 30 days. Replace fuel filter annually.
Cooling: Keep cooling fins and engine shrouds clean of debris.

Tip: Always disconnect spark plug wire before performing any engine maintenance.

Deck Adjustment & Blade Care

For an even cut, deck must be level.

Park on level surface; set cutting height to middle position.
Measure blade tip height from ground at all four corners of deck.
Adjust deck hanger rods to level (front-to-back and side-to-side within 1/4 inch).
Blade Sharpening: Disconnect spark plug. Remove blade bolt (left-hand thread). Sharpen at original angle (balance blade after sharpening). Torque blade bolt to 45-55 ft-lbs.
Belt Inspection: Check deck drive belt for cracks or fraying. Replace if worn.

WARNING! Wear heavy gloves when handling blades. Ensure blade is properly balanced to prevent vibration.

Storage & Winterization

Prepare mower for extended storage (over 30 days).

Clean entire mower, especially underside of deck.
Change engine oil and filter.
Add fuel stabilizer to tank; run engine 5 minutes to circulate.
Disconnect battery negative cable; store battery in cool, dry place (charge monthly).
Store in a dry, covered location; block up tires to reduce flat spots.

CAUTION! Do not store with gasoline in carburetor without stabilizer; it can cause gumming.
