To start the Toro Z Master Z253, ensure the parking brake is engaged, the PTO switch is off, move the throttle to the choke position if the engine is cold, turn the ignition key to start, and release it once the engine starts.
The recommended maintenance schedule includes checking the engine oil daily, cleaning the air filter every 25 hours, sharpening the blades every 25 hours, and inspecting belts annually. Consult the manual for detailed intervals.
If the mower won't start, check the fuel level, ensure the battery is charged, inspect the spark plug for wear, and verify that the safety interlocks are engaged.
To change the oil, run the engine for a few minutes, stop it, and allow it to cool. Remove the drain plug, let the oil drain completely, replace the plug, and refill with fresh oil. Check the level with the dipstick.
Check the PTO switch and wiring, inspect the belts for wear or damage, and ensure the battery is properly charged. If issues persist, consult a professional technician.
Remove the air filter cover, take out the filter, and gently tap it to remove debris. If it's excessively dirty, wash with soap and water, allow it to dry, and lightly oil it before reinstallation.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using ethanol blends higher than 10% to prevent engine damage.
Remove the blades from the mower, use a grinder or file to sharpen the cutting edge, maintain the original angle, and ensure blades are balanced before reinstallation.
Clean the mower thoroughly, change the oil, add fuel stabilizer, remove the battery, and store in a dry, sheltered area. Cover the mower to protect it from dust and moisture.
Check the belts for cracks, fraying, or wear. To replace, remove the deck cover, release belt tension, and replace with a new belt following the diagram in the manual.
