To start the Toro 521 38052C Snow Thrower, first ensure that the fuel shut-off valve is open. Set the choke to the full position, and move the throttle to the 'fast' position. Pull the starter rope or use the electric start if available. Once the engine starts, gradually move the choke to the off position.
Regular maintenance for the Toro 521 38052C includes checking and changing the oil, inspecting and replacing the spark plug, checking fuel lines, and cleaning or replacing the air filter. Additionally, ensure the auger and impeller are clear of debris and lubricate moving parts as specified in the user manual.
If the Toro 521 38052C won't start, check for fuel availability and ensure the fuel is fresh. Verify that the spark plug is clean and properly connected. Ensure the choke is set correctly and the throttle is in the 'start' position. If these steps fail, inspect the ignition system and fuel lines for issues.
To replace the drive belt, first disconnect the spark plug wire. Remove the belt cover and then the belt guide. Slide the belt off the engine pulley and the drive pulley. Install the new belt by reversing these steps, ensuring it is properly seated on both pulleys.
If the snow thrower isn't throwing snow far enough, check the auger and impeller for blockages. Ensure the chute is clear and positioned correctly. Inspect the drive belt for wear or slipping, and adjust or replace it if necessary.
To adjust the skid shoes, loosen the mounting nuts on each side of the skid shoe. Adjust the skid shoes to your desired height, ensuring both sides are even, then retighten the nuts securely. This adjustment helps to control the clearance between the scraper blade and the ground.
The recommended oil type for the Toro 521 38052C is SAE 5W-30 for winter conditions. This type of oil helps ensure proper lubrication at lower temperatures. Always check the user manual for any specific recommendations based on your local climate.
For off-season storage, drain the fuel or add a fuel stabilizer to prevent gum deposits. Clean the machine thoroughly, lubricate moving parts, and store it in a dry place. Disconnect the spark plug wire to prevent accidental starting.
To resolve a clogged chute, first, turn off the engine and wait for all moving parts to stop. Use a clean-out tool or stick to remove the packed snow from the chute. Avoid using your hands to prevent injury.
Excessive vibration can be caused by a damaged impeller or auger, loose parts, or an unbalanced drive system. Inspect these components for damage or wear and tighten any loose bolts or nuts. If the problem persists, consult a professional technician.
