To change the blades, first ensure the mower is turned off and disconnect the spark plug. Tilt the mower safely, use a wrench to remove the blade bolt, replace the blade, and tighten the bolt securely. Reconnect the spark plug before use.
Use SAE 30 oil for temperatures above 32°F and SAE 5W-30 for temperatures below 32°F. Always check the user manual for specific recommendations.
It is recommended to sharpen the mower blades after every 25 hours of use or at the start of the mowing season to ensure optimal performance.
After use, with the engine off and cool, use a garden hose to rinse off grass clippings and debris from the deck. Avoid using a pressure washer as it may damage components.
Check the fuel level, ensure the spark plug is connected, inspect the air filter, and verify the battery charge. If issues persist, consult the user manual or a professional technician.
Locate the height adjustment lever on the mower deck. Move the lever to the desired position to raise or lower the cutting height. Ensure the mower is turned off before making adjustments.
Uneven cutting may be caused by dull blades, incorrect tire pressure, or an improperly leveled deck. Check and address these areas for optimal performance.
To replace the drive belt, disconnect the spark plug, remove the deck, and locate the belt. Remove the old belt and install the new one, ensuring it is properly seated on the pulleys. Reattach the deck and reconnect the spark plug.
Excessive vibration can be caused by unbalanced blades, loose parts, or debris buildup. Inspect and tighten any loose parts, remove debris, and balance or replace blades as needed.
To winterize, clean the mower, drain the fuel or add a stabilizer, change the oil, remove the battery, and store in a dry, protected area. Cover the mower to protect it from dust and debris.
