4. Regular inspection

3. Check the nozzle spray status. If it is defective, replace

the nozzle.

DV2213165A

Removal of nozzle

1. Remove fuel injection pipe between nozzle holder and

injection pump.

2. Remove fuel return pipe.
3. loosen the Union screw(A) of nozzle holder with Nozzle

plug socket (EI.03004-0225)

4. Remove nozzle holder with sealing from the cylinder

head.

DV2213166B

CAUTION

• As the nozzle injection nozzle is designed to operate

under high pressure, you should handle it with
special care.

• Do not hold your hands under the fuel jet, as there

is a rise of injury. Do not inhale the atomized oil fuel.
If possible, work under an extraction system.
