The recommended oil type for the Toro Z Master Z528 74237 Mower is SAE 10W-30 or SAE 30 for temperatures above freezing.
The air filter should be checked and cleaned every 25 operating hours and replaced every 100 hours or annually, whichever comes first.
To adjust the cutting height, use the height adjustment lever located on the right side of the mower. Move the lever to the desired cutting height position.
Check the battery charge, ensure the fuel valve is open, verify the choke position, and inspect the spark plug for fouling. If issues persist, consult the user manual or a professional technician.
After each mowing session, clean the mower deck to prevent grass buildup, inspect the blades for damage, and check the oil level.
Regularly inspect the blades for dullness or damage. Sharpen or replace them as needed, typically every 25 hours of use or seasonally.
Check for debris stuck in the blades, inspect for bent or unbalanced blades, and ensure all bolts and fasteners are tight.
Maintain regular engine tune-ups, keep the air filter clean, and ensure the tire pressure is at the recommended level.
Drain the fuel tank, change the oil, clean the mower thoroughly, and store it in a dry place. Disconnect the battery to prevent discharge.
To replace the drive belt, remove the mower deck, release the tension on the belt, and carefully remove the old belt. Install the new belt by following the same path and ensure proper tension is applied.
