Do not: store fuel injector, fuel rail or engine that has
been loaded into fuel injector in an unprotected
environment.
External environment may damage the electronic and
mechanical parts of fuel injector.
Do not: take fuel injector as a handle when lifting
assebly parts.
It may damage fuel injector.
Do not: parts are in contact with each other during
storage.
It may damage fuel injector.
Do not: parts are in contact with each other during
transportation.
Collision may be caused and thus fuel injector may be
damaged.
Do not: knock fuel injector for troubleshooting when an
fault occurs.
It may damage fuel injector.
Do not: repalce the original fuel injector with one with
the part number not recommended.
It may seriously affect the performance of nozzle.
Please: pay special attention to protect sealing ring from
being cut by the installing seal during the installation of
fuel injector
Please: Use correct lubricant for installation, and
immediately it into the installing hole after applying
lubricating oil.
Protect sealing ring, to reduce pollution.
Please: add tests for the fuel injector whose needle
valve is stuck or cannot be mounted.
fuel injector for less than 5 seconds using 9-
Confirm the fault form of fuel injector
Please: before assembling fuel injector, make an oil-free
leak test to confirm that the needle valve of fuel injector
has been mounted.
It may prevent the needle valve of fuel injector froming
returning to the original position during the
transporation and transfer proces
s, thus resulting in fuel
leakage.
Please: prevent liquid from damaging fuel injector.
It may casue short circuit of solenoid coil.
Please: be careful to disassemble harness.
It may cause damage of terminal.
Please: use recommended lubricant when installing
connector.
It may cause corrosion to terminal.
Please: do not use fthe components that are dropped,
damaged or whose materials have problem, and describe
the problem using label.
Ensure to quickly find the root cause of fault.
Requirements for Installation of Fuel Injector
During the i
nstallation and removal process, please
strictly observe the following methods to avoid damage
to thefuel injector body and electronic components.
 Lubrication: Apply a small amount of lubricant
to the underside
of the sealing ring. ISO 10
light mineral oil or equivalent product is
recommended.

When conditions allow, apply lubricant to the
fuel injector seat, which is better than the effect
of being applied the seal ring. So that the fuel
injector contamination p
reduced to minimum.

Do not allow the spray plate to come into
contact with the lubricant, which may affect
the injection quantity. Do not dip the top of the
fuel injector to into the lubricant.
 All fuel injector sealing rings are factory
assembled. In principle, the sealing seals
