⚠ Be sure to stop the engine and remove the key before checking the belt tension.
⚠ Be sure to reinstall the detached safety shield after maintenance or checking.
⚠ Valve clearance must be checked and adjusted when engine is cold.
Tools: Feeler gauge
Tools: Belt tension gauge
⚠ Check after making sure nobody stands in the direction the fume goes.
Tools: Nozzle tester
⚠ Connect or disconnect load only when engine is stopped
⚠ Do not bleed a hot engine as this could cause fuel to spill onto a hot exhaust manifold creating a danger of fire.
⚠ DO NOT use or charge the battery if fluid level is below the LOWER mark.
⚠ Keep sparks and flames away from the battery.
Tools: Battery charger, Hydrometer or voltmeter
⚠ DO NOT remove the radiator cap while coolant is hot.
⚠ Work only after letting the engine and radiator cool off completely (more than 30 minutes after stopped).
⚠ Do not remove the radiator cap when the engine is hot.
⚠ Be sure to stop the engine before draining engine oil.
⚠ DO NOT drain oil from a hot engine. Allow engine to cool down sufficiently to avoid being burned.
⚠ Over-tightening may cause deformation of the rubber gasket.
⚠ Use only a KUBOTA genuine filter or its equivalent.
Tools: Filter wrench
⚠ Stop the engine when checking the fuel line; leaking fuel may cause a fire.
