Toro ProLine Recycler 21-inch 22145 Operator's Manual

To start the mower, ensure the fuel valve is open, engage the blade control lever, and pull the recoil starter handle.
Use SAE 30 oil for optimal performance in temperatures above 32°F, and 10W-30 for colder temperatures.
Sharpen the mower blade after every 25 hours of use or at least once a mowing season for the best results.
Check the fuel level, ensure the spark plug is connected, and inspect the air filter. Clean or replace parts if necessary.
Adjust the cutting height by repositioning the height adjustment levers located on each wheel of the mower.
Check the air filter every 25 hours of use. Clean it with soapy water and ensure it's dry before reinstalling. Replace if damaged.
Drain the fuel tank, run the engine until it stops, change the oil, and clean the mower before storing it.
It is not recommended to use the mower on wet grass as it may lead to clogging and uneven trimming.
Turn off the mower and disconnect the spark plug. Use a hose to rinse the undercarriage and remove grass clippings.
Check for debris lodged in the blade or undercarriage, ensure the blade is balanced, and tighten any loose parts.
