Toro TimeMaster 76-cm 21810 Operator's Manual

To start the Toro TimeMaster 76-cm 21810 mower, ensure the fuel valve is open, the mower is on a flat surface, and the blade control bar is disengaged. Pull the recoil starter handle firmly to start the engine.
If the mower does not start, check the fuel level, ensure the spark plug is connected, and verify that the air filter is clean. If the problem persists, consult the user manual for further troubleshooting steps.
It is recommended to change the oil after the first 5 hours of use and then every 50 hours of operation or once per season, whichever comes first.
To adjust the cutting height, move the height adjustment levers located on each wheel to the desired position. Ensure all wheels are set to the same height for an even cut.
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol blends higher than 10%.
To clean the mower deck, ensure the engine is off and cool. Use a garden hose to wash away grass clippings and debris. Dry the deck thoroughly to prevent rusting.
At the start of the mowing season, change the oil, sharpen or replace the blade, check the air filter, and inspect the spark plug. Also, ensure that all nuts and bolts are tightened and the wheels are properly aligned.
To replace the drive belt, first disconnect the spark plug and remove the mower's rear baffle. Remove the belt guard and the old belt, then install the new belt ensuring it is properly aligned with the pulleys. Reattach the belt guard and rear baffle.
Excessive vibration could be caused by a damaged blade or loose components. Inspect the blade for damage and ensure all nuts and bolts are secure. If the problem continues, consult a professional technician.
For off-season storage, clean the mower thoroughly, drain the fuel or add a fuel stabilizer, remove the spark plug and add a few drops of oil into the cylinder, then pull the starter rope to distribute the oil. Store in a dry, cool place.
