Toro CR-20 38110C Operator's Manual

To start the Toro CR-20 38110C Snow Thrower, ensure the machine is on a flat surface, set the choke to the full position, push the primer bulb twice, and then pull the starter handle briskly.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol.
Check if there is fresh fuel in the tank, the spark plug is not fouled, and the choke is in the correct position. Ensure the primer bulb is functioning and the fuel line is clear.
Drain the fuel tank, run the engine until it stops, change the oil, clean the machine, and store it in a dry place. Consider adding a fuel stabilizer to prevent any residual fuel from degrading.
First, disconnect the spark plug wire, remove the old spark plug with a socket wrench, install a new spark plug, and reconnect the spark plug wire. Ensure the new spark plug is gapped correctly.
Use SAE 5W-30 oil for optimal performance in cold weather. The engine capacity is approximately 20 ounces (0.6 liters).
Make sure the auger and impeller are clear of debris, adjust the skid shoes to increase the clearance, and operate at a slower pace to allow the machine to process the snow more efficiently.
Check for any loose or damaged parts, especially the auger and impeller. Tighten any loose bolts and replace damaged components as necessary.
Loosen the skid shoe bolts, adjust the height to your desired level, and then retighten the bolts. Ensure both sides are adjusted equally to maintain balance.
Turn off the engine and wait for all moving parts to stop. Use a clean-out tool or stick to remove the blockage. Never use your hands to clear the chute.
