To start the Toro 30103 mower, ensure the fuel tank is filled and the oil level is correct. Turn the fuel valve to the 'ON' position, engage the parking brake, pull the choke lever to the 'ON' position, and turn the ignition key to start the engine.
It is recommended to use SAE 30 oil for temperatures above 40°F (4°C) and 10W-30 for temperatures below 40°F (4°C). Always check the owner’s manual for specific oil recommendations.
Change the oil after the first 5 hours of use, and then every 50 hours of operation or annually, whichever comes first.
Check if there is fuel in the tank, ensure the fuel valve is open, inspect the spark plug for damage, and check the air filter for clogs. Ensure the safety switch is engaged and the battery is charged.
Regular maintenance includes checking and changing the oil, replacing the air filter, inspecting and cleaning the spark plug, sharpening the blades, and lubricating the moving parts.
Before storing, clean the mower thoroughly, change the oil, remove or stabilize the fuel, disconnect the battery, and cover the mower to protect it from dust and moisture.
Locate the height adjustment levers on each wheel. To raise or lower the deck, move all four levers to the same height setting.
This could be due to dull blades, incorrect cutting height, or mowing too quickly. Sharpen the blades, check the height settings, and mow at a slower pace.
Disconnect the spark plug, tilt the mower safely, and use a wrench to remove the blade bolt. Replace with a new blade and secure it firmly. Reconnect the spark plug before use.
Excessive vibration can be caused by loose or unbalanced blades. Check the blades for damage and ensure they are properly tightened. If the issue persists, consult a professional.
