Husqvarna RZ5424 9966659301 Parts Manual

To start the Husqvarna RZ5424, ensure the parking brake is engaged, the PTO switch is in the "Off" position, and the choke is engaged if the engine is cold. Then, turn the ignition key to the "Start" position until the engine fires, and release the key.
Check if the PTO switch is in the "On" position. Inspect the drive belt for wear or damage and replace if necessary. Ensure the battery is fully charged and the electrical connections are secure.
The oil should be changed after the first 5 hours of use and then every 50 hours of operation or once a season, whichever comes first. Always use SAE 30 or 10W-30 oil for optimal performance.
The recommended tire pressure for the Husqvarna RZ5424 is 15 psi for the front tires and 10 psi for the rear tires. Regularly check and maintain the tire pressure for optimal performance.
Excessive vibration could be due to unbalanced or damaged blades, loose hardware, or worn drive components. Inspect the blades for damage and balance them if necessary. Tighten any loose parts and replace worn components.
Ensure the blades are sharp and properly balanced. Adjust the deck level to the recommended height and maintain the engine's RPM at the optimal level. Regularly clean the deck to prevent grass build-up.
Check the air filter for blockages and clean or replace it if necessary. Ensure the engine oil level is correct and the cooling fins are clean and unobstructed. Avoid mowing in extreme heat or with excessive loads.
Ensure there is sufficient fuel and the fuel valve is open. Check the spark plug for fouling and replace if needed. Verify the battery is charged and the connections are tight. Inspect the ignition system for faults.
First, ensure the engine is off and the spark plug wire is disconnected. Remove the deck from the mower and then remove the belt guards. Replace the old belt with the new one, following the belt routing diagram, and reassemble.
Regular maintenance includes checking the oil level, inspecting the air filter, cleaning the mower deck, sharpening the blades, checking tire pressures, and inspecting belts and hardware. Perform these checks monthly or as specified in the manual.
