To start the Toro 521, first ensure the fuel valve is open and the choke is set to 'full'. Then, pull the starter handle firmly until the engine starts. Gradually adjust the choke to 'run' as the engine warms up.
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 or other ethanol blends above 10%.
Change the oil after the first 2 hours of operation, and then every 25 operating hours or annually, whichever comes first.
To adjust the skid shoes, place the snow thrower on a flat surface, loosen the skid shoe bolts, adjust them to the desired height, and then retighten the bolts. Ensure both shoes are adjusted equally to maintain balance.
Check the fuel level and quality, ensure the spark plug is clean and properly connected, verify the choke and throttle settings, and inspect the fuel line for clogs or damage.
Regular maintenance includes checking and changing the oil, inspecting and replacing the spark plug if necessary, checking the fuel system, and lubricating moving parts.
To replace the drive belt, remove the belt cover, disengage the old belt from the pulleys, position the new belt in place, and reattach the belt cover. Refer to the manual for pulley alignment instructions.
First, check if the auger cable is properly connected and tensioned. Inspect the auger drive belt for wear or damage and replace it if necessary.
Ensure the chute is clear of obstructions, the engine is running at full throttle, and the auger blades are sharp. Adjust the chute deflector to achieve the desired throwing distance.
Always wear appropriate winter clothing and eye protection, keep hands and feet away from moving parts, operate the machine only in well-lit conditions, and never point the discharge chute at people or pets.
