To change the oil, first ensure the mower is on a level surface. Remove the spark plug wire to prevent accidental starting. Drain the old oil by removing the oil drain plug. Replace the plug and refill with fresh oil recommended in the user manual.
Check the fuel level and ensure fresh fuel is in the tank. Inspect the spark plug for wear and replace if necessary. Verify that the air filter is clean and not clogged. Ensure all safety switches are engaged.
Sharpen the blades regularly and ensure they are balanced. Clean the deck to prevent grass build-up. Adjust the cutting height to suit the grass type and conditions.
Regular maintenance includes checking and changing the oil, inspecting and replacing the air filter, sharpening the blades, and checking tire pressure. Inspect belts and hoses for wear and replace as necessary.
Locate the height adjustment lever on each wheel. Move the lever to the desired position to adjust the cutting height. Ensure all wheels are set to the same height for an even cut.
Use clean, fresh unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content.
Check if the deck is level and adjust if necessary. Inspect the blades for sharpness and replace if dull or damaged. Ensure tire pressure is consistent on all wheels.
Refer to the owner's manual for the recommended tire pressure. Typically, it ranges from 12 to 15 psi, but always verify with the specific model guidelines.
Keep the battery terminals clean and free of corrosion. Check the electrolyte level if applicable, and charge the battery periodically during off-seasons. Store the battery in a cool, dry place.
Check the hydraulic fluid level and refill if necessary. Inspect for leaks in the hydraulic lines. If the issue persists, consult a professional technician as further diagnostics may be required.
