cautions for operating vehicles and vehicle engines.

•  The use of this product requires technical knowledge about the mode of opera-

tion and the superstructure of respective vehicle or vehicle engine. The product 
is connected to particular points. These are in different places for each vehicle 
and observe vehicle-specifi c rules while connecting.

•  Before all activities, get information about the necessary rules and instructions

•  Beware of hot engine parts while using the product. Always keep the product 

away from hot engine parts.

•  Never leave vehicle unattended while using the product.
•  When working on running vehicle engine, risk of being injured by hot, moving 

or electrically charged parts exists. The fan wheel, V-Belts, exhaust manifold 
and the parts of ignition system leading high voltage are particularly dangerous. 
Electrical ventilators can start unexpectedly and quickly without pre-warning!

•  Avoid the direct contact with live components.

•  Take particular care when dealing with the high voltage of ignition system. Not 

only the electrical shocks itself is dangerous, but this may also cause frequent 
resulting injuries due to arbitrary evasive movement. The high voltage (up to 
15.000 Volt and more) may skip quite large distances, in particular damaged or 
worn components, fragile insulations can be dangerous.

•  Fuel  and  fuel  vapours  are  easily  fl ammable.  Smoking  and  naked  fl ames  are 

prohibited while handling fuels.

•  Fuel injection systems are under pressure. Loosen the connections and hoses 

slowly and carefully only when the motor is stationary and ignition is switched 
off. 

•  Always collect escaping fuel. Never allow escaping fuel to come in contact with 

hot engine parts. Danger of Fire! Always keep fi re extinguisher easy to reach.

•  Always check this for tightness after completing the working on the fuel system.
•  It is necessary to avoid skin and eye contact while dealing with fuels. If fuel gets

6.  T-Connector
7.  Outlet hose
8.  Pressure relief valve

 

Fuel reaching the outlet hose (7) during depressurisation must be always collected in 
suitable container. Necessarily pay attention to the applicable rules and instructions 
for dealing with fuels.
If the fuel injection system do not have any test connection, it is possible to fi t a tem-
porary connection for the product for the test using the provided auxiliary hoses (1),
