To start the Toro Power Clear 621ZE, ensure the fuel valve is open, the choke is in the ON position, and the ignition key is inserted. Pull the starter rope or use the electric start button if equipped. Once the engine starts, gradually move the choke to the OFF position.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol content to prevent engine damage.
It's recommended to change the oil after the first 2 hours of operation and then annually or after every 25 hours of use, whichever comes first.
Check if there is fresh fuel in the tank, the ignition key is properly inserted, and the choke is set to ON. Also, inspect the spark plug for wear or damage and replace if necessary.
Regularly inspect the auger for debris and clean it after each use. Check the shear pins and replace them if broken. Lubricate the auger bearings annually for optimal performance.
Ensure the chute is not clogged with snow. Check if the auger and impeller are functioning properly. Inspect the belts for wear and adjust or replace if necessary.
Drain the fuel or add a fuel stabilizer to prevent clogging. Clean the snow thrower thoroughly and store it in a dry area. Disconnect the spark plug to avoid accidental starting.
To adjust the skid shoes, loosen the mounting nuts and set the desired height between the scraper blade and the ground. Retighten the nuts to secure the position.
Yes, but make sure to adjust the skid shoes to raise the scraper blade above the gravel. This prevents the machine from picking up and throwing gravel.
Excessive vibration may indicate a damaged or imbalanced auger. Inspect the auger and impeller for damage and ensure all mounting hardware is secure. Replace any damaged components.
