Toro S-620 38162 Operator's Manual

Ensure the power cord is connected and the fuel tank is filled. Set the choke to the START position, press the primer bulb a few times, and pull the starter handle. Once it starts, move the choke to the RUN position.
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol-blended fuels above E10.
Change the oil after the first 5 hours of use, and then every 25 hours of operation or once per season.
Check the fuel level and ensure the fuel is fresh. Verify that the spark plug is clean and connected properly. Ensure the choke is in the correct position and try priming the engine.
Turn off the engine and disconnect the spark plug. Use a clean-out tool or stick, never your hands, to remove the snow or debris from the chute.
Drain the fuel tank, change the oil, clean the exterior, and check for any loose or damaged parts. Store in a dry place and cover to protect from dust.
Disconnect the spark plug wire, use a spark plug wrench to remove the old plug, and install a new one with the correct gap. Reattach the spark plug wire.
Check for loose or damaged parts, particularly the auger and impeller. Tighten any loose bolts and replace any damaged components.
Ensure the skid shoes and scraper blade are properly adjusted to the correct height for the snow conditions. Consider using a snow thrower spray to reduce chute clogging.
After each use, remove snow and moisture from the snow thrower. Apply a thin layer of oil or a rust-preventative spray to metal parts before storage.
