Maintenance Schedule

Regular maintenance is crucial for safety, performance, and warranty compliance.

Engine Care

Refer to separate engine manual for detailed specifications.

1. Oil Change: Run engine to warm oil. Drain via plug into pan. Refill with SAE 10W-30 (or as specified for temperature) to proper level on dipstick.
2. Air Filter: Remove cover, clean foam pre-filter (if equipped) with soapy water, dry. Replace paper element if dirty. Never run engine without filter.
3. Spark Plug: Disconnect wire, clean area, remove plug. Check gap (0.030" typical). Replace if electrodes are worn or cracked.
4. Fuel System: Use fresh, clean gasoline. Add fuel stabilizer for storage. Replace in-line fuel filter annually.

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

Cutting Deck Maintenance

A clean, balanced deck and sharp blades are essential for a quality cut.

1. Blade Removal/Sharpening: Disconnect spark plug. Block deck up safely. Remove bolt securing blade. Sharpen blade evenly to maintain balance. Replace if cracked or badly worn.
2. Deck Cleaning: After each use, scrape off accumulated grass. Hose down (avoid electrical components) and let dry to prevent rust.
3. Belt Inspection: Check V-belts for cracks, fraying, or glazing. Adjust tension if loose (refer to manual for specific procedure).
4. Deck Leveling: Park on level surface. Measure blade tip height at all four corners. Adjust deck hanger links to achieve even height (typically 1/8" lower in front).

WARNING! Blades are extremely sharp. Wear heavy gloves when handling.

Storage & Winterization

Proper storage prevents fuel system issues and corrosion.

1. Add fuel stabilizer to nearly full gas tank. Run engine for 5 minutes to circulate treated fuel.
2. Change engine oil and filter (if equipped) while engine is warm.
3. Remove spark plug, add a teaspoon of oil into cylinder, and pull starter cord slowly to coat cylinder walls. Reinstall plug.
4. Clean entire mower thoroughly, especially underside of deck. Apply light oil to exposed metal parts to prevent rust.
5. Disconnect battery negative cable. Store battery in a cool, dry place on a wood surface, and charge periodically.
6. Store in a clean, dry place, preferably covered.

CAUTION! Do not store near open flame, water heater, or other ignition sources.
