Toro Z Master 6000 Series 78922 Operator's Manual

The recommended maintenance schedule includes checking the engine oil and air filter before each use, cleaning the air filter every 25 hours, changing the engine oil every 100 hours, and sharpening the blades every 8 to 10 hours of use.
If the mower won't start, check the battery charge, ensure the fuel tank is filled with fresh gasoline, verify the spark plug connection, and inspect the air filter for clogs.
To improve cutting performance, regularly sharpen the blades, adjust the cutting height to suit your lawn conditions, and ensure the deck is clean and free of debris.
To change the blades, first disconnect the spark plug for safety, then use a wrench to remove the blade bolts. Replace with new blades and tighten the bolts securely.
Adjust the cutting height by using the lever located on the side of the mower deck. Make sure the mower is on a level surface and set the height to your desired level.
Check for debris or buildup under the deck, ensure the blades are balanced and securely fastened, and inspect the spindle assemblies for damage.
Regular maintenance such as timely oil changes, air filter cleaning, blade sharpening, and storing the mower in a dry, sheltered place will help ensure longevity.
Use unleaded gasoline with a minimum octane rating of 87 and ensure it contains no more than 10% ethanol.
To winterize, clean the mower thoroughly, drain the fuel system or use a fuel stabilizer, change the oil, and store the mower in a dry place.
Ensure the tire pressure is equal on all wheels, check that the blades are sharp and balanced, and verify that the deck is level.
