To perform a basic maintenance check, ensure the engine is off and cool. Check the oil level and condition, inspect air filters, examine blades for wear, and ensure tire pressure is adequate. Regularly clean the mower deck to prevent grass build-up.
If the mower won't start, check the battery connections and charge if necessary. Ensure the fuel tank is filled with fresh fuel and inspect the spark plug for damage or wear. Additionally, verify the safety switches are engaged.
The oil should be changed after the first 5 hours of use, and then every 100 hours of operation or annually, whichever comes first. Always use the oil type recommended in the owner's manual.
The recommended tire pressure for the Toro Z Master Z255 is typically around 13 psi for drive tires and 15 psi for caster tires. Always refer to the operator's manual for precise specifications.
To adjust the cutting height, use the height of cut lever located on the mower deck. Move the lever up or down to set the desired cutting height. Ensure both sides are adjusted equally for an even cut.
To winterize, remove all fuel from the tank or add a fuel stabilizer. Clean the mower deck and blades, and change the oil. Disconnect the battery and store it in a cool, dry place. Cover the mower to protect it from dust and moisture.
To sharpen the blades, first disconnect the spark plug. Remove the blades using a wrench, then use a grinder or file to sharpen them, maintaining the original angle. Rebalance the blade before reinstalling.
Excessive vibration can result from unbalanced blades, loose components, or worn bearings. Check and rebalance the blades, tighten all nuts and bolts, and inspect bearings for wear. Replace any damaged parts.
To replace the air filter, locate the air filter cover, remove it, and take out the old filter. Insert the new filter, ensuring it is seated properly, and replace the cover. Refer to the manual for specific instructions.
Uneven cutting can be caused by dull blades, incorrect tire pressure, or an unlevel deck. Sharpen the blades, check and adjust the tire pressure, and level the deck as needed.
