Be careful not to come into direct contact with the injected spray. The spray destroys any cells it
touches. It may also cause blood poisoning, etc. Check the injection nozzle after confirming that
nobody is standing in the direction of the spray.
Fuel Tightness of Delivery Valve
1. In the same way as to check the pump element fuel tightness,
turn the engine ten times or more with the starter so that the
pressure is increased to specified pressure.
2. Set the plunger at the bottom dead center to reduce the
delivery chamber pressure to zero.
3. Measure the fall time for the pressure to drop to the reference
pressure from the specified initial pressure.
4. If the measurement is less than the allowable limit, replace the
pump with new one or repair with a Kubota-authorized pump
service shop.
