PRECAUTIONS
When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
Keep the antenna as far as possible from the electronic
control units.
Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
Adjust the antenna and feeder line so that the standingwave
radio can be kept smaller.
Be sure to ground the radio to vehicle body.

CLEANLINESS INSTRUCTIONS WHICH MUST BE FOLLOWED WHEN WORKING ON THE
HIGH PRESSURE DIRECT INJECTION SYSTEM
Risks Relating to Contamination
The system is very sensitive to contamination. The risks caused by the introduction of contamination are:
Damage or destruction of the high pressure injection system and the engine
Seizing or leaking of a component
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) get into the system during dismantling or into the circuits via the fuel unions.
The cleanliness principle must be applied from the filter to the fuel injectors.
WHAT ARE THE SOURCES OF CONTAMINATION?
Contamination is caused by:
Metal or plastic chips
Paint
fibres:
Boxes
Brushes
Paper
Clothing
Cloths
Foreign bodies such as hair
Ambient air
etc
IMPORTANT: It is not possible to clean the engine using a high pressure washer because of the risk of dam-
aging connections. In addition, moisture may collect in the connectors and create electrical connection mal-
functions.
INSTRUCTIONS TO BE FOLLOWED BEFORE ANY WORK IS CARRIED OUT ON THE INJEC-
TION SYSTEM
Ensure that you have the plugs for the unions to be opened (bag of plugs sold at the Parts Store - Nissan
part No.: 16830 BN700, Renault part No.: 77 01 206 804). Plugs are to be used once only. After use, they
must be thrown away (once used they are soiled and cleaning is not sufficient to make them reusable).
Unused plugs must be thrown away.
Ensure that you have hermetically resealable plastic bags for storing removed parts. Stored parts will
therefore be less subject to the risk of impurities. The bags must be used only once, and after use they
must be thrown away.
Lint-free towelettes to be used for injection pump related service purpose. The use of a normal cloth or
paper for cleaning purposes is forbidden. These are not lint-free and may contaminate the fuel circuit of
the system. Each lint-free cloth should only be used once.
INSTRUCTIONS TO BE FOLLOWED BEFORE OPENING THE FUEL CIRCUIT
For each operation, use new thinner (used thinner contains impurities). Pour it into a clean receptacle.
For each operation, use a clean brush which is in good condition (the brush must not shed its bristles).
