Toro TimeCutter Z5040 74374 Operator's Manual

To change the oil, first run the engine for a few minutes to warm it up, then turn it off. Place an oil pan beneath the engine, remove the oil drain plug, and let the old oil drain completely. Replace the drain plug and fill the engine with new oil, following the specifications in your owner's manual.
If your mower won't start, check the battery connections, fuel level, and make sure the spark plug is clean and properly connected. Also, ensure that the safety switches are engaged and that the mower blades are not engaged.
It is recommended to check and clean the air filter every 25 hours of operation and replace it annually or more frequently if it's damaged or excessively dirty.
Uneven cutting may be due to dull blades, uneven tire pressure, or a misleveled deck. Ensure the blades are sharp, check tire pressure, and level the deck according to the user manual.
Adjust the cutting height by using the deck lift lever located on the mower. Move the lever to the desired position to set your preferred cutting height.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol to prevent engine damage.
To store your mower for the winter, clean it thoroughly, change the oil, add a fuel stabilizer to the gas tank, and remove the battery. Store it in a dry, sheltered place.
If the blades won't engage, check the PTO switch, belt tension, and ensure the engine is running at full throttle. Inspect the blade engagement system for any damage or disconnection.
To improve fuel efficiency, perform regular maintenance such as changing the oil, replacing the air filter, and keeping the blades sharp. Additionally, avoid mowing at full throttle unless necessary.
Regular maintenance includes checking the oil level, cleaning or replacing the air filter, inspecting the blades, checking tire pressure, and ensuring all bolts and connections are secure.
