WARNING! Always replace bent or cracked blades. Never weld or straighten a damaged blade.

Engine Maintenance

Refer to the separate engine owner's manual for detailed procedures.

• Oil Change: Use SAE 30 or 10W-30 detergent oil (check manual for exact spec). Run engine to warm oil, then drain via dipstick tube or drain plug. Refill to proper level on dipstick.
• Air Filter: Service paper filter by tapping clean. Replace if dirty or annually. Clean foam pre-filter with soapy water if equipped.
• Fuel System: Use clean, fresh unleaded gasoline. Add fuel stabilizer for storage. Replace fuel filter annually.
• Spark Plug: Gap and replace per engine manual specifications.
• Battery: Keep terminals clean and tight. Charge if not used regularly. Store in a cool, dry place off concrete in winter.

Storage & Winterization

Proper storage prevents fuel system damage and corrosion.

1. Add fuel stabilizer to a full tank and run engine for 5 minutes to circulate.
2. Change engine oil (dirty oil contains acids that can damage engine).
3. Remove battery, clean terminals, and store fully charged in a cool, dry place.
4. Clean entire mower thoroughly, especially the underside of the deck.
5. Store in a clean, dry place, preferably covered.

Tip: Consider fogging the engine cylinder through the spark plug hole for long-term storage (see engine manual).
