The recommended maintenance schedule includes checking the engine oil level before each use, cleaning the air filter every 25 hours, sharpening the blades every 25 hours, and changing the engine oil every 50 hours. Refer to the owner's manual for a complete schedule.
If the mower does not start, check the fuel level and ensure the fuel valve is open. Verify the battery connections and charge the battery if necessary. Ensure the parking brake is engaged and the blade control switch is off.
To change the blades, first disconnect the spark plug wire and ensure the mower is on a flat surface. Use a block to prevent blade rotation, then remove the blade bolt and blade. Install the new blade, ensuring it is properly aligned, and tighten the bolt securely.
To adjust the cutting height, locate the deck lift lever on the mower. Move the lever to the desired height position, which ranges from 1.5 inches to 4.5 inches. Ensure both sides are set to the same height for an even cut.
Excessive vibration could be caused by unbalanced blades, loose hardware, or debris lodged in the deck. Check and balance the blades, tighten any loose bolts, and clean out any debris from the deck area.
To store the mower, clean it thoroughly and remove any grass clippings. Stabilize the fuel or drain it completely. Disconnect the battery and store it in a cool, dry place. Cover the mower with a breathable cover to protect it from dust.
The recommended oil type for the Toro Z Master Z350 engine is SAE 10W-30, which provides optimal performance across a wide range of temperatures. Always check the owner’s manual for specific oil recommendations.
To improve fuel efficiency, regularly maintain the engine by changing the oil and air filters, keep the blades sharp, and avoid running the engine at full throttle when not necessary. Also, mow during cooler parts of the day to reduce engine strain.
Common signs of a worn-out belt include squealing noises, visible cracks or fraying on the belt, and inconsistent cutting performance. Regularly inspect the belt and replace it if any of these symptoms are present.
To calibrate the steering, ensure the mower is on a flat surface. Adjust the tracking by evenly adjusting the control rod nuts on both sides until the mower travels straight when both steering levers are pushed forward.
