Regular maintenance for the Kubota RTV-520 involves checking and changing the engine oil, inspecting the air filter, checking tire pressure, and ensuring the coolant level is adequate. Refer to the owner's manual for specific intervals and procedures.
If the RTV-520 won't start, first check the battery connections and charge the battery if necessary. Ensure the fuel level is sufficient and inspect the spark plug for any signs of wear or damage.
Transmission issues may arise from low hydraulic fluid or improper adjustment of the gear shift. Check the fluid levels and consult the service manual for adjustment procedures.
The recommended engine oil for the Kubota RTV-520 is SAE 10W-30 or 15W-40, depending on the ambient temperature. Always use oil that meets or exceeds API service classification.
To adjust the throttle, locate the throttle cable adjustment screw near the carburetor. Loosen the lock nut, adjust the screw to the desired tension, and then retighten the lock nut.
The recommended tire pressure for the Kubota RTV-520 is typically around 22 psi for both front and rear tires. Refer to the tire sidewall or the owner’s manual for specific recommendations.
To replace the air filter, locate the air filter housing, remove the cover, and take out the old air filter. Insert the new filter and replace the cover securely. Ensure the filter is seated properly to prevent debris from entering the engine.
If the RTV-520 is overheating, check the coolant level and radiator for any blockages. Ensure the fan is functioning properly and inspect the thermostat for proper operation.
To engage the differential lock, come to a complete stop, and then move the differential lock lever to the engaged position. The vehicle may need to move slightly to fully engage the lock.
Regularly inspect the brake fluid level and check for any signs of leaks. Examine the brake pads and rotors for wear, and ensure that the brake pedal feels firm and responsive.
