Regular maintenance includes checking and changing the oil, replacing air filters, checking tire pressure, and inspecting belts and blades for wear. Follow the maintenance schedule in the user manual for detailed guidance.
Use SAE 30 oil for temperatures above 32°F and 10W-30 for temperatures below 32°F. Check the owner's manual for any updates or specific recommendations.
Check the battery connections, ensure the fuel is fresh, and inspect the spark plug for wear. If problems persist, consult the service manual or a professional technician.
Inspect the blades for dullness or damage. Sharpen or replace them as needed. Also, check the deck height and ensure it's set correctly for an even cut.
First, disconnect the spark plug. Remove the mower deck and any obstacles to access the belt. Release tension, remove the old belt, and install the new one following the belt routing diagram.
Excessive vibration may be caused by unbalanced or damaged blades, loose components, or worn bearings. Inspect and address each area to resolve the issue.
Replace the air filter every 100 hours of operation or annually, whichever comes first. In dusty conditions, check and replace it more frequently.
The recommended tire pressure is typically around 14 PSI for the rear tires and 12 PSI for the front tires. Refer to the manual for any specific adjustments.
Check for worn or loose steering components, ensure proper tire alignment, and inspect the steering linkage. Tighten or replace parts as necessary.
Inspect the engine and transmission for signs of wear or damage. Check seals and gaskets, and replace them if necessary. Clean any oil spills to prevent further issues.
