3. Do not mow on slopes greater than 15 degrees. Mow up and down slopes, not across.
4. Engage parking brake, disengage PTO, and turn off engine before leaving operator's position.
5. Keep hands and feet away from moving parts and the discharge chute.

DANGER! Gasoline is highly flammable. Refuel outdoors in a well-ventilated area with the engine off and cool. Do not smoke near fuel.

Assembly & Setup

2. Attach the seat by aligning and bolting to the seat plate.
3. Connect the battery cables (red to positive, black to negative).
4. Check tire pressure and inflate to recommended PSI (listed in Specifications).
5. Perform initial engine oil check and add oil if necessary (see Engine Care).
6. Add fresh, unleaded gasoline with a minimum octane rating of 87.

NOTE: Retain all packaging until assembly is complete to ensure no parts are missing.

Maintenance Schedule

Regular maintenance is crucial for safety and performance. Refer to engine manual for specific engine service.

Engine Care

Use only recommended oil type and viscosity (SAE 10W-30 is typical).

1. Oil Change: Run engine to warm oil. Disconnect spark plug wire. Drain oil via drain plug into pan. Refill with correct amount.
2. Air Filter: Replace paper element or clean foam pre-cleaner regularly. Service more often in dusty conditions.
3. Spark Plug: Check gap and condition every 100 hours. Replace if electrodes are worn.
4. Fuel System: Use fuel stabilizer if storing over 30 days. Replace fuel filter annually.

WARNING! Engine components become extremely hot during operation. Allow engine to cool completely before performing any maintenance.

Deck Adjustment & Blade Care

A level deck is essential for an even cut.

1. Park on a level surface. Set cutting height lever to desired position.
2. Measure distance from blade tip to ground at all four corners of the deck.
3. Adjust deck hanger links to level the deck (front slightly lower than rear by 1/8" to 1/4" is recommended for proper discharge).
4. Blade Sharpening/Replacement: Disconnect spark plug wire. Safely block deck. Remove blade bolt (note orientation). Sharpen blade evenly, maintaining balance. Replace if cracked or excessively worn.
5. Use the deck wash port after each mowing to prevent grass buildup.

Storage & Off-Season Care

Proper storage prevents fuel system issues and corrosion.

1. Add fuel stabilizer to gas tank and run engine for 5 minutes to circulate.
2. Change engine oil and filter at the end of the season.
3. Remove battery, clean terminals, and store in a cool, dry place on a trickle charger.
4. Thoroughly clean the mower deck and underside. Lubricate all grease points.
5. Store in a clean, dry place, preferably covered.

CAUTION! Never store the mower with fuel in the tank indoors or in an enclosed area without proper ventilation.

Troubleshooting

Reset: For electrical issues, check and reset circuit breakers near battery.
